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—reliant on actual conditions, it can be up to five times more. Things have become so dangerous, 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 around 90% of their time indoors, excellent indoor air quality is a necessity for good health, regardless if it’s in our homes or our workplaces. To help handle this pollution and increase our indoor air quality, we can take different measures. But first, we are required to understand some lingo consistently 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 created—and certified—to trap at least 99.97% of .3-micron particles (less 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 destroyed. MERV Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With rankings ranging from 1–16, you should find a max rating that specifies the filter will destroy 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.
