Learning how to test the air quality in your home involves using certain tools that spot specific pollutants. We’ll narrow down the most common offenders, then share solutions on how to keep them at bay year-round.

The Top 6 Most Common Indoor Air Pollutants

While your home may feel clean in other areas, indoor air tends to be stagnant and filled with all sorts of irritating pollutants. A 2021 study directly linked filthy indoor air with worsening asthma symptoms, more frequent sick days, and an increased risk for headaches.

Let’s take a look at your indoor air and see what could be causing worsening health.

Dust and Dirt

If you don’t make a regular habit of dusting and vacuuming your home, all this debris has to go somewhere…and it’s usually in the air! These indoor air pollutants are extremely common and irritating, often causing itchy eyes, dry throats, and clogged sinuses.

Chemicals

Learning how to test the air quality in your home can also help you spot the presence of excess chemicals. Everyday products or activities, such as burning coal or using over-the-counter cleaning products with bleach, can contribute significantly to worse indoor air.

Pollen

Do you live in a state that sees a regular pollen season in the spring or early summer? That pollen can sneak through open windows or doorways, eventually accumulating indoors and lingering for days.

Pet Dander and Odor

Even if you’re not allergic to pets, their dander, hair, and odor can gradually make your indoor air quality unpleasant. Dogs tend to be dirtier than indoor cats, and they often track in dirt that can make the air even worse.

Mold and Mildew

Mold isn’t just gross: with regular exposure, it’s very bad for your health. Mold spores can remain indoors indefinitely, building up until they start causing respiratory problems or mold spots.

Viruses and Bacteria

Did you know viruses and bacteria don’t just linger on surfaces, but can hang in stagnant indoor air for several hours? Clean indoor air not only smells fresher, it can reduce the risk of spreading airborne illness when someone in the home is sick.

3 DIY Methods for Testing Indoor Air Quality

You can learn how to test the air quality in your home with all kinds of tools. We recommend the following three indoor air quality testing tools for their higher levels of accuracy and ease of use.

CO2 Monitor

How do you test indoor air quality on a general level? Stagnant indoor air is more likely to have higher levels of pollutants, so CO2 monitors measure the amount of carbon dioxide. Carbon dioxide is a chemical compound that builds up with limited ventilation.

These monitors are easy to read: the lower the number, the fresher your indoor air. Ideal numbers are between 400 and 800 for occupied rooms.

Air Quality Monitor

This generalized monitor measures larger airborne particles like dust, dander, and pollen by tracking particulate matter levels in the air. Homeowners can mount these on the wall or use an air purifier with a monitor.

Mold Testing Kit

If you want to learn how to test indoor air quality, don’t skip out on mold spores. Mold testing kits involve putting out a dish that gradually gathers mold spores in the air, giving you a general idea of the next steps you need to take.

The Importance of Ventilation and Filtration

Figuring out how to check the air quality in your home should go hand in hand with proactive habits. Homes need daily ventilation and filtration to keep indoor air pollutants at low levels.

Ventilation works by bringing in fresh air to dilute and remove indoor pollutants such as dirt, dust, and airborne viruses or bacteria. Home air purifiers clean the air with fans that pull air through filters, where many pollutants are captured.

Improve Your Indoor Air Quality with Regular HVAC Maintenance

Have you ever turned on your HVAC and felt your sinuses kick into high gear? Runny eyes and a clogged nose shouldn’t be the price you pay for a cooler home, so improve your indoor air quality with yearly HVAC maintenance.

An experienced HVAC technician can replace old air filters, clear out dirty clogs, and spot potential leaks to make sure you’re not accidentally making your indoor air worse.
