The constant development of industries and increase in manufacturing are some of the factors that contribute to deteriorating air quality, both inside and outside our homes. It doesn’t matter how often you clean, your house still has some level of air pollution, including dust, pollen, mold, cleaning chemicals, to mention a few. And with the wildfires that occur every year, the smoke easily makes its way through doors and windows, negatively impacting your lungs. If you’re worried about the air you breathe at home, an indoor air quality monitor can help you detect the various pollutants. It also tells you if your air purifier or HVAC filter is working as expected. You can then take the necessary steps to clean up your air. Whether you’re looking to upgrade your indoor air quality sensor or looking for a new one, here are the top five indoor air quality monitors in the market.
