What You Need to Know About Indoor Air Quality08/08/2016 Most people realize how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual home often is more polluted—depending on actual conditions, 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 in homes. Since Americans spend an average of 90% of their time indoors, superior indoor air quality is crucial for decent health, no matter if it’s in our homes or our workplaces. To help contain this pollution and better our indoor air quality, we can take different measures. But first, we need to grasp some lingo often used to discuss indoor air quality. HEPA HEPA is a term many people have heard or seen, but did you realize it stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”? HEPA filtration systems are designed—and certified—to trap at least 99.97% of .3-micron particles (tinier than the diameter of a human hair) from the air that filters 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 rankings ranging from 1–16, you should pursue a max rating that reveals the filter will remove more contaminants and allergens from your air without confining the airflow of your home comfort system.
