Did you know that indoor air can be more polluted than outdoor air? According to the United States Environmental Protection Agency (EPA), indoor air may be 2-5 times more polluted than outside air.
Indoor air pollutants can cause asthma attacks, itchy eyes, sneezing, and runny nose. According to the American Lung Association, radon and tobacco smoke can cause even more dangerous health effects, including lung cancer.
The good news is that using an air purifier can make your indoor air healthier by filtering out your space’s allergens, odors, and other pollutants. Also, the EPA recommends using an air purifier.
