How to Interpret the Results of a Home Air Quality Test
Posted in Air Quality, on July 30, 2026
Home air quality testing can provide answers to questions about health and safety at home, and help families get to the bottom of persistent allergies and questions about mold, allergens, or other pollutants. At SafeAir, we offer comprehensive air quality testing across Southern Ontario to help promote and maintain a healthy indoor life. After indoor air quality testing, we’ll create a detailed report about our findings. Unlike other DIY home air quality tests, however, we’ll also help you interpret the results so you know precisely what it means and how you can make meaningful improvements. Here’s what we think is important to know.
Understand What Is Being Measured
Air quality tests usually measure and look for a selection of common pollutants, like particulates, dust, mold spores, or volatile organic compounds. The results may be displayed as concentrations, as a comparison to a baseline level (such as if you have annual indoor air quality testing performed), or a certain category of risk. Just like the results from the doctor’s office, each measurement can be assessed for risk based on your concerns, needs, or goals.
Identifying What “Normal” vs “Elevated” Means
A “normal” home air quality test generally indicates that airborne particles are within acceptable ranges, based on industry and Health Canada guidelines. An “elevated” reading, on the other hand, suggests that we’ve discovered higher-than-expected pollutants and that more investigation or remediation may be recommended. Of course, results can be affected by many things, like weather, renovations, occupancy and ventilation, so repeated or regular testing may help even out the curve.
Determining the Source of Air Quality Issues
When your air quality testing returns elevated readings, the next step is to assess mitigating factors. If you have a high pollen count during spring, well, that’s to be expected! But other elevated test results can indicate problems like poor airflow, moisture issues, or VOC-emitting products. Mold spores without visible mold growth may indicate hidden infestations behind walls or inside HVAC systems, and further investigation can help you find and eliminate these issues.
Specialized Vs General Air Quality Testing
At SafeAir, we offer a range of services for homeowners to tackle common and uncommon air quality problems. General environmental assessments can look for common pollutants and look at the way air moves around your home. Often, it’s the small changes or minute improvements that can have a huge effect on your results, and our customized post-testing report will help direct you to the kinds of changes you might like to make.
If your air quality testing results show elevated levels in specific contaminants or in particular rooms, we may provide a more detailed remediation or recommendation plan to help you choose the best and most effective corrective action. Either way, our team’s personal touch and attention to detail will help you feel confident with your next steps.
