What You Need to Know About Indoor Air Quality08/08/2016 The majority of people are aware of how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual living space can 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 inside. Since Americans spend an average of 90% of their time indoors, excellent indoor air quality is vital for good health, despite if it’s in our homes or our workplaces. To help handle this pollution and improve our indoor air quality, we can take multiple measures. But first, we must to absorb some lingo often used to discuss indoor air quality. HEPA HEPA is a term a lot of 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 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 captured. MERV Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With rankings ranging from 1–16, you should look for 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.
