What You Need to Know About Indoor Air Quality08/08/2016 Most people realize how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average living space might be more polluted—contingent on actual conditions, it can be up to five times more. Things have become so bad, the EPA has indoor air pollution classified as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found indoors. Since Americans spend about 90% of their time indoors, superior indoor air quality is vital for decent health, no matter if it’s in our homes or our workplaces. To help manage this pollution and improve our indoor air quality, we can take different measures. But first, we must to understand some terms often used to discuss indoor air quality. HEPA HEPA is a term many people have heard or seen, but did you recognize it stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”? HEPA filtration systems are designed—and certified—to confine at least 99.97% of .3-micron particles (less than the diameter of a human hair) from the air that passes through the system. This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With ratings ranging from 1–16, you should find a higher rating that specifies the filter will filter more contaminants and allergens from your air without restricting the airflow of your home comfort system.
