What You Need to Know About Indoor Air Quality08/08/2016 Many people realize how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual home might be more polluted—depending on actual situations, it can be up to five times more. Things have become so dangerous, the EPA has indoor air pollution ranked as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found inside. Since Americans spend about 90% of their time indoors, excellent indoor air quality is vital for great health, no matter if it’s in our homes or our workplaces. To help contain this pollution and improve our indoor air quality, we can take different measures. But first, we must to grasp some terms often used to discuss indoor air quality. HEPA HEPA is a term a lot of 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 moves through the system. This significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped. MERV Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With metrics ranging from 1–16, you should look for a higher rating that specifies the filter will destroy more contaminants and allergens from your air without confining the airflow of your home comfort system.
