What You Need to Know About Indoor Air Quality08/08/2016 The majority of people understand how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual home can be more polluted—contingent on actual circumstances, it can be up to five times more. Things have become so bad, the EPA has indoor air pollution tiered 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, excellent indoor air quality is crucial for great health, no matter if it’s in our homes or our workplaces. To help handle this pollution and better our indoor air quality, we can take different measures. But first, we are required to understand some lingo often used to discuss indoor air quality. HEPA HEPA is a term most people have heard or seen, but did you know it stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”? HEPA filtration systems are engineered—and certified—to trap 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 describes the effectiveness of an air filter. With metrics ranging from 1–16, you should look for a max rating that specifies the filter will filter more contaminants and allergens from your air without limiting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
