What You Need to Know About Indoor Air Quality08/08/2016 Many people are aware of how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average living space might 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 tiered 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, superior indoor air quality is vital for decent health, regardless if it’s in our homes or our workplaces. To help contain this pollution and improve our indoor air quality, we can take different measures. But first, we need to absorb some terms commonly used to discuss indoor air quality. HEPA HEPA is a term most 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 capture at least 99.97% of .3-micron particles (tinier than the diameter of a human hair) from the air that moves 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 expresses the effectiveness of an air filter. With metrics ranging from 1–16, you should find a max rating that reveals the filter will remove 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.
