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 typical house might be more polluted—depending on actual situations, 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 in homes. Since Americans spend an average of 90% of their time indoors, superior indoor air quality is a necessity for decent health, no matter if it’s in our homes or our workplaces. To help manage this pollution and increase 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 designed—and certified—to capture 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 greatly 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 metrics ranging from 1–16, you should pursue a top 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.
