Home Air Check is an advanced analysis of an air sample taken in a home that provides a report on the total concentration of Volatile Organic Compounds (VOCs) and the total concentration of Mold Volatile Organic Compounds (MVOCs) present in the home.
About the Home Air Check test
Each Home Air Check™ test can sample up to a 2,000 sq. ft. area. Therefore, if the area you wish to test is 2,000 sq. ft. or under, we recommend ordering a single Home Air Check™ test kit. For testing areas greater than 2,000 sq. ft., or for testing a completely separate/closed-off area of the home such as a basement, we recommend ordering multiple Home Air Check tests. Special package pricing is available for multiple test kit orders.
Home Air Check is extremely affordable and is available with different pricing options depending on whether the kit is ordered with or without a Formaldehyde test.
Once the sample is received by Prism, it will be analyzed within 5 business days and an easy-to-read report that details the levels of VOCs and MVOCs (actively growing mold) plus a list of the predicted sources of the VOCs will be emailed to you.
Home Air Check tests for the Volatile Organic Compounds (VOCs) in your home air. VOCs are also referred to as airborne, or gaseous, chemicals. Home Air Check looks for over 400 chemical compounds that can be present in the air, and then reports the total level of VOCs in your home. In addition, Home Air Check looks for any actively growing mold in your home, since when mold is in its active growth phase it releases chemicals into the air, called Mold Volatile Organic Compounds (MVOCs). Then, instead of reporting chemical compound names, we report the most likely sources of the chemical contamination in your home so you can take action to improve your home air quality.
No, currently Home Air Check cannot monitor for dust, pollen, pet dander, and mold spores because these contaminants are airborne particles, not airborne gases. Home Air Check detects gaseous air contaminants that can’t be seen with the naked eye. However, we do partner closely with other laboratories that perform these types of analyses and can recommend one if you are interested.
The price you pay covers all costs associated with the test. We provide you with the sampling kit to use to collect the air sample, the pre-paid postage to return the sampling equipment to us, the analysis of the results, and any telephone or chat line support after the results are emailed you, to help resolve any issues that may have been found.
The only additional cost is the shipping fee to send the sampling kit to you.
No, Home Air Check does not currently monitor for Radon.
Home Air Check can detect the solvents used in illegal drug production. However, it cannot detect the drug itself because most drugs are not volatile. The chemicals that off-gas into the air are mostly volatile and the test could pick those up if they were entering an adjoining space.
No, the Home Air Check test is a single-use air sample collected by you and returned to the lab for analysis. If you wish to retest after you have made changes in your home to improve the air quality, you would need to purchase another test.
No. Asbestos is a fiber and Home Air Check does not monitor for fibrous materials.
Home Air Check can detect the chemical compounds associated with decaying animal flesh. However, currently, the test cannot detect for animal infestations, e.g., rodent droppings.
Home Air Check can detect many chemical compounds in the air (more than 400); however, the test results won't name the specific chemicals found and their exact concentrations. The Home Air Check test is designed to be a lower-cost screening test that uses an air sample to scan for hundreds of chemical compounds, and takes that chemical profile and puts it into source categories so that the non-chemist, i.e., average consumer, can understand. Those categories are classified as lifestyle or building-related, and include many common sources like personal care, odorants/fragrances, paints/varnishes, and other adhesives and solvents. You can view a sample report here, to see exactly what the report will look like and what type of information is reported.
Each category is given a value of Normal, Moderate, Elevated, or Severe, and guidelines are given as to what types of products could be included in that category so that the homeowner can locate them and contain them or remove them from the home completely. From this report, you should be able to ascertain whether or not a specific chemical that you may be concerned about could be in your home air, and what types of products may be contributing to the air pollution.
Our laboratory can perform a much more comprehensive analysis that will give detailed information about specific chemicals, but those tests are usually performed by professionals because of their much higher cost and the need for interpretation by a chemist.
VOCs, or Volatile Organic Compounds, are invisible gases that are emitted from solids and liquids found in the home, such as building materials, cooking sources, gasoline and fuel, air fresheners, paints/varnishes, dry-cleaning, laser printers, carpeting, adhesives, cleaning solutions, and many other sources. These chemicals can build up in houses, especially in the winter and summer months when homes are generally closed up. Repeated exposure to VOCs can cause blurred vision, headaches, nausea, dizziness, coughing, lethargy, burning eyes, respiratory irritation, skin rashes, reduced lung function, respiratory illness, concentration difficulties, depression, and, in extreme cases, loss of consciousness and suffocation. Higher exposure can lead to liver damage, kidney and central nervous system irregularities. Some VOCs can cause cancer.
MVOCs are gases (chemicals) produced by actively growing mold. Just as humans expire gases, so do molds. These chemicals can be monitored to determine the level of actively growing mold in the house. A Home Air Check™ measurement is an excellent way to determine the level of mold growing in a house — even behind walls. This is possible because Home Air Check is a chemical analysis of the air, and chemicals move more freely through a house than mold spores (particulates) which can be trapped by walls and thereby go undetected. When mold levels are elevated and there is chronic exposure in the home, some individuals can experience negative health effects, or worsening of existing illnesses, that could run the gamut from mild to serious. These health effects could include allergies, skin irritations, asthma, respiratory infection, and toxic poisoning. In addition, individuals with suppressed immune systems may be particularly vulnerable to illnesses caused by mold contamination.
Yes, these materials will stay in the house until they are removed. The house is full of VOC sources as mentioned in the above question “What are VOCs,” and the amount in the air will eventually reach a constant level within a few days to a week in a closed house. MVOCs, since they are generated by growing organisms, can increase in concentration if mold growth is expanding in the house. This can lead to unsafe levels.
The best way to maintain a low level, and thus, safe level of volatile chemicals in the house is to remove sources of VOCs and MVOCs from the house, if they can be identified. VOCs and MVOCs can be reduced, but not eliminated, by circulating fresh air from an open window or ceiling/attic exhaust fans.
If a house is opened up through windows and exhaust fans, the VOCs should be at their lowest level, assuming you are not living in heavy industrial chemical areas with chemical plants or fuel refining plants. If you live in a heavily industrialized area, you should probably have your air quality checked since it could be significantly above recommended standards.
The level of MVOCs will be the lowest in a dry home. If windows are open and the house becomes damp, then higher levels of microbial activity will be present and higher levels of MVOCs can be produced. In this case, turning on dehumidifiers and/or air conditioners and keeping the house closed will produce lower MVOCs.
The length of time that it takes for VOCs or MVOCs to leave the home depends upon their source. Gasoline cans and kerosene lamps kept in an attached garage or in the home can generate significant VOCs, since they are generally stored in larger containers. VOCs from these sources can only be reduced by removing them from the home. If the VOC source can not be removed from the home, replacing the home air with fresh air on a regular basis will keep the VOCs at their lowest levels and will reduce your exposure.
If the VOCs are from furnishings like wood and plastic, they will be at their highest levels when they are new, but will continue to emit VOCs for many years. In addition, VOCs from water-based paints can be present for up to 18 months after application.
MVOCs will continue to be emitted from areas that have mold. The only way to remove this source is to have the existing mold removed and then prevent building materials like wood and drywall from getting wet, either from excessive humidity, leaky plumbing, or water intrusion from rain or ground water.
Because Home Air Check uses state-of-the-art technology, an entire chemical fingerprint of the home is produced which allows us to predict the primary and secondary sources of air contamination. Along with the analysis reports, we provide a Contamination Index™ Report that lists these potential contamination sources, along with recommendations on how to remove or reduce them. If, however, the VOC or MVOC levels exceed acceptable standards, Prism can assist with the necessary next steps to improve the home's air quality with a consultation, further testing, or referral to a knowledgeable industrial hygienist or other professional specializing in indoor air quality issues.
Why test your air
The United States Green Building Council (USGBC) and the European Union (EU) suggest that levels greater than 500 ng/L of VOCs could pose a health hazard in homes. High levels of VOCs can lead to respiratory irritation, mental confusion, headaches, lethargy, or worse, and can exacerbate existing medical conditions such as asthma. The levels of these compounds tend to be higher in homes built after 1970 because fresh air infiltration has been reduced to conserve heat with improved insulation, tighter door and window seals, and better construction technology in general. MVOCs detected above 30 ng/L indicate significant actively growing mold. Even this slightly elevated level could produce health concerns for some people.
What you don’t know about the air in your home could hurt you and your family. Many of the things we are exposed to every day in our homes, including products and materials we use on a routine basis, are considered harmful chemicals. In addition, many areas of the country have problems with humidity, and mold is often found actively growing in homes, silently causing more health concerns. There are serious health risks with repeated and prolonged exposure to VOCs and mold. These risks are elevated for individuals already suffering from chronic respiratory illnesses such as asthma, allergies, chronic bronchitis and emphysema. Some VOCs are considered Hazardous Air Pollutants (HAPs) and have been linked to cancer. Our homes are supposed to be our safe-havens – not places where we are put at risk. With such a comprehensive, inexpensive test available, why wouldn’t you want to give yourself peace of mind that you’re doing everything you can to protect the well-being of the ones you love most?
Yes, absolutely. It is a wise decision to have a complete pre-inspection and indoor air quality assessment performed prior to putting your home on the market to make sure no hidden issues will be revealed after a potential buyer has made an offer to buy your home. In this case, you would need to have a Home Air Check Professional test (a more detailed analysis of the home air) conducted by a home inspector who participates in our Home Air Check Professional network. A Home Air Check Professional test gives you the ability to conduct a more detailed analysis of the top 10 chemical compounds found in your home’s air, should you need to have this information. Plus, the home inspector takes care of performing the test and handling all the paperwork and shipping. Having a certified report from a home inspector that the air quality in your home meets recommended or acceptable levels gives credibility to the overall value of your home. Please note that a Home Air Check Professional test will cost more than our online price since it is performed by a service professional and it is a more detailed analysis. You will need to contact the local provider for all pricing.
Many times we just can’t understand why we feel sick and tired on a daily basis, and why we develop symptoms that worsen over time. For instance, those who are living in homes contaminated by mold may not be able to smell any odor and may be unaware that a problem exists. The sudden onset of food allergies and digestive problems can go undiagnosed, or even misdiagnosed. And long after you’ve finished using a product containing VOCs, you could be feeling its effects. If you or a loved one has unexplained allergic reactions or illnesses occurring on
a continual basis, the source of the problem could be indoor air pollutants.
Breathing bad air can cause many health effects, from mildly irritating to extremely serious. Symptoms such as frequent headaches, dizziness, fatigue, nausea, confusion, coughing, wheezing, itchy eyes, nose and throat irritation can be indicators that the quality of air in the home is poor – especially if these symptoms subside once you leave the house. Other more serious health problems that can arise with poor indoor air quality are asthma exacerbation, digestive problems, and damage to the liver, kidneys and central nervous system. Some air contaminants are so harmful that they can even cause cancer.

The Home Air Check advantage
With a single test, Home Air Check provides a comprehensive picture of chemical levels that the home occupants are breathing in the home. It also indicates a level of actively growing mold present in the home. Since these chemicals are tested simultaneously, the sophisticated analysis becomes less expensive. Also, the samples are collected without the use of toxic chemicals, so there are no health risks using Home Air Check. No other home air test can match the level of completeness, sophistication, prediction, and value of Home Air Check.
Prism has spent the last 2 decades developing state-of-the-art testing methods that are effective for the collection and analysis of ambient air samples at a very low cost. For even the most expensive tests, the cost is still half of what other laboratories charge due to the level of automation utilized at the Prism laboratory.
Your analysis report will describe the levels of VOCs and actively growing mold in the home, as well as provide a Contamination Index™ that lists the predicted sources of air contaminants and suggestions for removal from the home. If extremely high levels of air contaminants are found, Prism will offer you assistance in finding an Indoor Air Quality Professional that can address your concerns and help you determine the next steps in improving your indoor air quality.
Home Air Check and Prism Analytical Technologies are significantly different from our competition in a number of ways:
1. Prism is the only laboratory to offer a prediction of the likely sources of chemicals in the home, so that an action plan can be created.
2. Prism is the only laboratory with enough sensitivity to pick up mold VOCs in the home.
3. Prism is the only laboratory that will perform a full GC-MS analysis (detailed chemical analysis) for under $300.
4. Prism is the only laboratory that you can easily get professional support after your analysis. That is we will talk to you about your report for no added fee and we are easy to reach.

6. Prism has been an innovator in developing tests that try to look at all the chemicals in your air, not a select set defined by regulatory groups.
7. There is no other product like Home Air Check on the market. With this product you receive the following:
a. The total level of VOCs in your home.
b. The total level of mold VOCs in your home.
c. The predicted sources of the VOCs in your home so you can improve your air quality.
d. Phone, email or chat with a professional about your report if you have any questions or concerns
e. You can get a $400 professional product for less than $100.
One of the main benefits of Home Air Check™ is that it can still see chemicals being emitted from growing mold even if the mold is behind a wall. Most mold tests require the mold to be almost obvious before they are able to detect it. Home Air Check can detect mold even when it is not visible.
Basically, they are tiny seeds, microscopic and invisible to the naked eye, that spawn from molds and float through outdoor and indoor air. When they land in an appropriate environment, they will grow into new mold.
Yes, mold spores travel through the air and by foot traffic and can make it into the home via the outdoor air and grounds. Although these spores are in the home and can end up on many surfaces, they do not grow and damage surfaces unless they have nutrients and a moisture source.
Potentially, yes. Potted plants have mold spores and active mold growth in the soil. Potting soils generally have plenty of nutrients and water that can produce mold growth which in turn can produce mold spores. Mold spores are also produced by some food products such as blue cheese.
Mold spores are everywhere outdoors and are being swept by winds into locations where there may not be any mold growth. These spores can be brought into the home through the air and by foot traffic. If an outdoor test is not performed, the home may be incorrectly assessed as having a mold problem.
Home Air Check is only measuring for the chemicals generated by active mold growth and not for mold spores. Therefore, the presence of mold spores does not influence the ability of Home Air Check to accurately identify active mold growth inside the home. The only instance where an outdoor Home Air Check sample is recommended is when the home is located in a forested area or other area where substantial, active mold growth outdoors, close to the home is expected.
Prism normally does not suggest monitoring for mold growth in crawl spaces that are highly vented. This is because the chemicals (mold VOCs) emitted by any mold growth are swept quickly out of the vents. In these cases, a visual inspection of the underside of the house is a preferred method for determining any mold growth. Where the crawl space is not vented nor has minimal venting, Home Air Check can be an effective tool for finding active mold growth.
If the crawl space is highly vented, the chemicals generated by the mold growth would be quickly swept out through the vents before they could get into the home and be detected using Home Air Check. Also, if a sealed, plastic membrane has been installed between where the mold growth is and the interior of the home, the mold would not be detected. However, if the crawl space is not vented nor has minimal venting, and there is no sealed, plastic membrane, the mold VOCs can usually be detected inside the home.
Where there is a moisture source such as a plumbing leak, condensation, or water intrusion, there most likely is mold. If you can’t see the mold, it doesn’t mean there isn’t mold growing behind walls or underneath flooring. When mold is in an active growth phase, it releases chemicals into the air, called Mold Volatile Organic Compounds (MVOCs). With Home Air Check, these MVOCs can be easily detected, thus indicating that mold, while it cannot be seen yet, is growing somewhere in the home. The benefit of performing the Home Air Check test to detect hidden mold is that no mold is disturbed and thus spread during the test. The drilling of holes in drywall or the removal of wall coverings and flooring to try and test for mold spores is not necessary, and thus eliminates the possibility of making the mold infestation worse and the expense of damaging walls and flooring.
If Home Air Check detects hidden mold in your home, it will be imperative to call a mold remediation specialist to locate the source, repair it, and safely remove the mold.
No, we are not a mold remediation company. Our Home Air Check test can detect the presence of actively growing mold. If it is determined that your home has a mold issue, you will need to consult a mold specialist to have it removed.
No, our test does not speciate molds. The Home Air Check test looks for the chemicals that are released into the air from actively growing mold, called Mold Volatile Organic Compounds or MVOCs, and reports on the total concentration of MVOCs found in the home. If you need a test that specifically identifies mold species and their individual concentrations, we partner with a few excellent biological laboratories that do this type of analysis, and would be happy to recommend one to you.
If your report lists the MVOC levels as being elevated, there is a water intrusion somewhere. It could be underneath the carpeting, if it has gotten wet in the past and has never dried out completely. In order for mold to grow, there must be a water source. This can include chronic condensation as well as an active leak or water intrusion. The first step is to identify any water source and then remove it or stop the water from collecting. You may want to check underneath the carpeting to see if there is any source of water that may be producing the mold VOCs.
How Home Air Check works
After you place an order for the Home Air Check test, Prism will ship a sampling kit to your home in order for you to collect an air sample. The kit will contain a sample tube that will capture the chemicals present in your home air, a small sample pump to pull the home air through the sample tube, some simple instructions, and a pre-addressed, pre-paid box to return the kit to our lab for analysis. Sampling time is approximately 3 hours. That’s it! The test is extremely simple and easy to perform – anyone can do it!
The sampling tube is a solid material that emits no chemicals while being utilized. In fact, the entire methodology from sampling to analysis has been developed as a “Green” Method.
Although the Home Air Check test is extremely simple to perform, we understand that some people may not want to do the test themselves, and would rather have the assessment done by a professional. In this case, we recommend our Home Air Check Professional test, a more detailed analysis of the home air, conducted by a home inspector, home service contractor, or industrial hygienist participating in our Home Air Check Professional network. Please note that a Home Air Check Professional test will cost more than our online price since it is performed by a service professional and it is a more detailed analysis. You will need to contact the local provider for all pricing.
Home Air Check was designed to be a do-it-yourself air quality assessment. When you purchase a Home Air Check test, we ship a small sampling device directly to your home for you to collect the air sample. After collecting the air sample, you then return the sampling device and sample to our lab where our chemists will perform an analysis of your air using Gas Chromatography-Mass Spectrometry and/or Fourier Transform Infrared Spectrometry analytical instrumentation. After the analysis is completed, we will then email you the results of your test. We then provide phone support if needed to help you understand the results. The price covers all of these steps, including the shipment of the air sample back to our lab.
After you place an order for a Home Air Check test kit, we send you a small sampling device to collect an air sample in your home. The sampling time takes about 3 hours. After the sample is collected, you then return the complete kit to our laboratory, where we will analyze the air sample using sophisticated state-of-the-art analytical instrumentation for over 400 Volatile Organic Compounds (VOCs) that can be found in home air. In addition, we will look for 21 specific mold compounds that can be generated when mold is actively growing in a home. A detailed report is then generated. In this report will be a Total VOC concentration level – a total of all the VOCs found in your home. The US Green Building Council recommends a level of less than 500 ng/L to be considered a healthy environment. (The median US home is about 1,200 ng/L.) A total concentration of Mold VOCs is also listed. Generally, this number should be less than 8 ng/L or you have active mold growth you need to find. The report also includes a Contamination Index. Instead of reporting individual chemical compound names and values, we give you a prediction from what sources or materials in home the contaminating chemicals are emanating, such as gasoline, paint, adhesives, odorants, personal care products, etc. This report is then emailed to you within 5 days of receipt of your air sample. We can provide phone or chat line support to answer any questions you have and to help you improve your air quality.
Formaldehyde is listed by the U.S. Environmental Protection Agency (EPA) as a Hazardous Air Pollutant (HAP) and is a known carcinogen (cancer-causing agent). Since Formaldehyde is frequently found in homes, particularly in homes that are newly constructed or have been recently remodeled, we recommend that you include a Formaldehyde test with your Home Air Check kit order. Special pricing is offered when a Home Air Check test is combined with a Formaldehyde test. We also offer a single test for Formaldehyde only.
There are a number of ways to reduce or eliminate the level of formaldehyde in your home, including:
1. Increase the amount of fresh air in the home by opening windows or getting an HVAC system that brings in outdoor air. Most HVAC systems just recirculate the home air and do not replace it with outdoor air. When detected, formaldehyde is normally low in most homes, but could be easily lowered further by increasing fresh air.
2. Air conditioning and dehumidifiers have been shown to help by condensing the formaldehyde with the water condensate that is generated on the cooling coils.
3. Some air cleaners have VOC reduction systems that can remove some of the formaldehyde. However, do not expect them to remove all or even a large portion of the formaldehyde unless they have been specifically tested and demonstrated to do so.
4. Cabinetry and prefabricated flooring are two large sources of formaldehyde. If these sources are removed, they can lower the formaldehyde level; however, they should be replaced with materials that are not constructed with formaldehyde glues.
Formaldehyde is found in many products and processes, including some natural sources. Carpets typically do not contain significant amounts of formaldehyde anymore. However, carpets can trap formaldehyde within its fibers from other sources. And, there are other types of flooring that do contain formaldehyde. As with any chemical compound, locating and removing or containing sources is the first step to lowering the formaldehyde concentration. If sources cannot be located or it is not possible to remove the source, then increasing the amount of ventilation will dilute the amount of formaldehyde in the air and lower the concentration.
Home Air Check accuracy
Yes. Home Air Check was designed so anyone can easily use it in their own home. After you receive your results we provide telephone or chat line assistance to answer any questions you might have and to help you improve your air quality. Professionals would use a test like Home Air Check (and we have many Professionals who are actually using Home Air Check for their air quality assessments) to find the chemical sources in your home that might be causing you to have health issues. Professionals can provide a visual inspection of the home that we cannot provide, and they might be able to identify the source without testing. However, the cost of a having a Professional come to your home could be extremely expensive. If you wish to go in that direction, we could recommend someone in our network.
Home Air Check has been designed to identify the chemicals that are present in the home air so that a solution can be developed to reduce or remove them and improve your air quality. Home Air Check looks for over 400 chemical compounds (VOCs) and identifies hundreds of compounds in every air sample. The qualitative accuracy of monitoring these compounds is 95 - 100% since each has a very characteristic “fingerprint” that can be identified.
Chemical compound, or VOC, concentrations can vary throughout the home and change with time, so the absolute concentration is less important than which VOCs are present. The presence of each compound tells something about the home and how to potentially improve the air quality of the home. However, to get the most accurate quantitative result for each Home Air Check sample, calibration standards are added during the analysis to calibrate the instrument and to provide the most accurate concentration that can be obtained.
The Home Air Check test is analyzed by Prism Analytical Technologies, Inc. (Laboratory ID 166272), an air testing laboratory accredited by the AIHA Laboratory Accreditation Programs (AIHA-LAP), LLC in the Industrial Hygiene accreditation program for GC/MS Field of Testing as documented by the Scope of Accreditation Certificate and associated Scope.
In order to become accredited, a laboratory must undergo a rigorous application and review process every two years. This accreditation process takes months to complete and each laboratory must formally demonstrate its competence to conduct testing, thereby increasing the credibility of the testing results. This conformity assessment encompasses all operations of the lab, including management, technical competence of the lab personnel, the validity of the testing methodology, and the validity of the results. Technical competence of a lab depends upon its quality control systems, plus qualifications, training and experience of the lab staff, demonstration of proficiency in testing, appropriate handling of samples, suitable testing environment, properly calibrated and maintained equipment, traceability to national standards and accurate reporting.
Therefore, you can rely on the accuracy and validity of the Home Air Check test and its results because of Prism’s status as an AIHA accredited laboratory.
Our laboratory is AIHA accredited for analytical chemical analysis to identify chemicals in indoor air. On occasion we have been asked to provide further information for legal proceedings, and our results have not been challenged.
Home Air Check, however, was designed as a screening tool – to report the source of chemicals in the home, not the chemicals individually. Prism looks at all the chemicals our analytical instrumentation identifies, with a high degree of certainty, and predicts where they are coming from, e.g., paint, gasoline, personal care products, mold, etc. As with any prediction, however, there is some uncertainty and if a significant issue is predicted, more detailed follow-up testing is usually recommended.
Secondhand smoke / Thirdhand smoke
Home Air Check does not specifically detect for nicotine or tobacco. However, Prism has developed another test called Tobacco Smoke Check that does detect for the presence of certain chemical markers known to be present in tobacco smoke. The Tobacco Smoke Check test can be ordered from this site, either as a stand-alone test, or in conjunction with a Home Air Check test.
How to use Home Air Check
The objective of taking an air sample in the first place is to determine the quality of the indoor air. This may sound obvious, however, if changes are made in lifestyle or the building contents or if temporary steps are taken to improve indoor air quality, or IAQ, the sample will not be truly reflective of IAQ. Generally, temporary changes in lifestyle or in the building diminish the value of the results because the homeowners will change back as soon as the sampling is over and the impact of the changes will remain unknown. The only suggested change is to keep all interior doors open during sampling to facilitate air movement and to help uncover "hidden" sources.
The following is a list of things to consider to ensure that a sample is taken that truly reflects IAQ:
Eliminate potential interfering sources that produce high levels of volatile chemicals that may cloud or skew the results or hide actual problems
- No frying for 48 hours
- No cooking or baking for 24 hours
- No unusual activities such as painting or gluing
Do not change lifestyle
- Run the HVAC system normally
- Keep exterior doors/windows closed unless normal lifestyle includes leaving them open
- Do not turn on vent fans unless they are always left on
Do not alter the building or its contents
- Do not remove items from the home unless the items will not be returned to the home
- Do not remove cars or machinery from an attached garage
- Do not leave overhead garage doors open
After you receive your report
Gasoline and petroleum VOCs are surprisingly very common in homes. They come from a number of possible sources that are stored in attached garages, including: gasoline cans; lawn equipment (mowers, trimmers, leaf blowers); recreational vehicles (ATVs, mini-bikes, etc.); and gasoline-powered generators. In addition, petroleum products like gasoline, kerosene, and oil can spill onto the garage or basement floor and become trapped in the cracks or subflooring beneath. Also, even the smallest amount of gasoline on clothing, rags, or the hands can affect the levels of VOCs the Home Air Check test detects. It is very important that you remove any potential sources of petroleum products from the garage or basement, and store them in a detached shed or other structure, away from the home. These products are toxic and contain carcinogens (cancer-causing agents) such as benzene and toluene. For more information on the hidden sources of gasoline and petroleum in your home, watch our video.
Many fragrances, like citrus or pine, would show up in this category. While many chemical compounds can contribute to odorants and fragrances, a chemical class called terpenes is dominant in this case. Terpenes occur naturally in a variety of plants, although most are synthetically manufactured for fragrance and flavor purposes. Many essential oils contain relatively large amounts of this type of chemical compound. There are some additional sources for these compounds besides fragrance and flavor products, such as turpentine, pharmaceutical products, insect repellants, cosmetics, cleaners, and air fresheners.
Check the Odors and Fragrances section of your report. Was that section also marked as “elevated” or “severe”? Many products that contain odorants and fragrances also contain alcohols, so these are likely linked even though the source is not apparent. We suggest focusing on the odorants and fragrances category and searching for offending sources to remove from the home. We would advise being careful using “non-VOC” products. Just because something is marked “non-VOC” does not mean that no chemicals are getting into your air; it's just a different set of chemical compounds.
No, we’re sorry, but the specific chemical data are not available. Home Air Check is a low-cost air survey test that is designed to provide you with easy-to-understand general information regarding the primary sources of VOCs in your home. A complete chemical listing is not useful without an interpretation by a degreed chemist, which is very costly, and therefore, is not available with Home Air Check. If you feel that you need more extensive testing that will provide the detailed chemical information, we recommend that you contact an industrial hygienist who specializes in indoor air quality issues.
If you are referring to biological organisms living in carpet, like dust mites, the Home Air Check test does not test for those, with the exception of mold. However, it is true that carpet is often a sink for many things that could cause problems. We typically recommend hard surface floors with area rugs that can be removed and cleaned if at all possible.
Rented apartment units can be especially difficult to deal with regarding air quality because you usually do not have much control over the structure of the building, and VOC sources from your neighbors can easily enter your air. Also, previous tenants sometimes leave behind traces of themselves that are not immediately apparent, and the leasing company or agent may have performed renovations or other activities that can also leave traces of contamination. If you know your neighbors well enough, ask them if they have or use any of the products listed in those categories that came back as Elevated or Severe. We have encountered several instances where a neighbor's unit had a significant effect on air quality and they were not even aware there was a problem. After you have looked for any possible sources and removed or contained them (e.g., cleaning products can be stored in a container with a tight fitting lid when not in use, apply personal care products with the bathroom exhaust fan running, etc.), the next step is to reduce the amount of the remaining sources by increasing the amount of ventilation, either fresh or filtered re-circulated air. Most homes do not have adequate air changes per hour so this aspect should be addressed regardless of the air quality levels. In an apartment, this is more difficult, however, because you have only limited ability to control the air exchange rate. Another option for difficult air quality issues is to use an air purifier. This purifier must include a VOC filter or removal system as well as a particulate filter. Often, this type of purifier includes something to remove biological contaminants, too. When run continuously, one or more air purifier units can reduce the VOCs by as much as half.
