Here are a few ways you can check the air quality in your home.
Purchase an indoor air quality monitor – An indoor air quality monitor or IAQ is a device that tests for particulate matter (pollen and dust), chemical pollutants, humidity, temperature, carbon monoxide (CO), carbon dioxide (CO2), and formaldehyde levels.
Call a professional to test your home for mold – At-home mold test kits are cheap and unreliable. Call a professional if you think you have mold in your home.
Install carbon monoxide alarms – Anything that burns gas creates CO, including woodburning and gas fireplaces. CO alarms are just a few dollars and can save your life.
Conduct a radon test – Radon, like carbon monoxide, is odorless, colorless, tasteless, and is completely undetectable without a purpose-built detective device. Short-term radon test kits can be bought online or at any home improvement store. Long-term tests can be bought as well, remaining in your home from 90 days to a whole year.
