What You Need to Know About Indoor Air Quality08/08/2016 The majority of people realize how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical home might be more polluted—depending on actual situations, it can be up to five times more. Things have become so damaging, the EPA has indoor air pollution tiered as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found inside. Since Americans spend an average of 90% of their time indoors, good indoor air quality is a necessity 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 multiple measures. But first, we need to understand some lingo commonly 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 capture at least 99.97% of .3-micron particles (tinier than the diameter of a human hair) from the air that passes through the system. This greatly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are destroyed. MERV Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With ratings ranging from 1–16, you should find a max rating that specifies the filter will remove more contaminants and allergens from your air without confining the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
