How Hac Works


Collect a home air sample using a Home Air Check test kit and send it back to us in 14 days for the most accurate results (late return fees may apply)


We analyse your sample and send you a report detailing likely sources of VOCs in your home.


We identify the likely sources for you in an easy-to-read report with targeted advice for improving your air quality.

Using Our Indoor Air Quality Test

Get Your Air Tested

We offer an advanced, comprehensive method for measuring the presence of most major potentially harmful chemical compounds (VOCs), actively growing mould, formaldehyde and tobacco smoke.

Performing the test is simple. After placing your order, we will send you a kit that contains a sampling pump, a sampling tube for collecting the air samples, and detailed instructions. One test covers an area of up to 200 m2.

After collecting the air sample(s), simply return the entire kit to us using the provided pre-paid labels and packaging. Once your sample is received, a chemical analysis will be performed in the Prism laboratory by a degreed chemist using sophisticated, state-of-the-art analytical instrumentation – specifically, Gas Chromatography-Mass Spectrometry and Fluorescence Spectroscopy. The instrumentation is routinely calibrated and can be traced to National Institute of Standards and Technology (NIST) reference materials. Using proprietary air scanning methodologies and algorithms, we look for most major chemical compounds (VOCs) that can be found in home air, including 21 specific mould compounds that are produced when mould is actively growing. We also look for the presence of formaldehyde and tobacco smoke (depending on the tests you ordered).

From this analysis, comprehensive reports are generated. With the VOC test, you will receive information on the total amount of VOCs and the total concentration of mould VOCs present in your home air. The US Green Building Council recommends a total VOC level of less than 500 ug/m3 (microgrammes per cubic metre) to be considered a healthy environment (the average home is over 1,200 ug/m3). The total level of mould VOCs should be less than 8 ug/m3 to avoid a problem with active mould growth and possible allergic reactions. You will also receive a VOC Contamination Index which includes the prediction of the possible sources or materials in the home that could be producing the contaminating chemicals.

The Formaldehyde test report indicates the level of formaldehyde present in the air you breath and the Tobacco Smoke test report shows you the likelihood of second hand smoke present in your home. Both of these reports also offer advice on how to mitigate the presence of formaldehyde and tobacco smoke. The reports are emailed to you within 7-10 business days of receipt of your air sample(s).

Armed with all of this information, you will be well equipped to take appropriate steps to remove or reduce the sources of contamination and ultimately improve the quality of air your family breathes. If needed email support is available to answer any questions you may have.
