What You Need to Know About Indoor Air Quality08/08/2016 Many people realize how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average house can be more polluted—depending on actual conditions, it can be up to five times more. Things have become so dangerous, 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, superior indoor air quality is a necessity for good health, regardless if it’s in our homes or our workplaces. To help manage this pollution and better our indoor air quality, we can take several measures. But first, we need to understand some lingo consistently 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 created—and certified—to confine at least 99.97% of .3-micron particles (smaller 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 captured. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With metrics ranging from 1–16, you should find a max rating that specifies the filter will destroy more contaminants and allergens from your air without restricting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
