What You Need to Know About Indoor Air Quality08/08/2016 Most people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual home can be more polluted—contingent on actual circumstances, 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 about 90% of their time indoors, good indoor air quality is a necessity for good 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 several measures. But first, we are required to absorb some lingo often used to discuss indoor air quality. HEPA HEPA is a term many 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 capture 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 significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped. MERV Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With ratings ranging from 1–16, you should find a max rating that reveals 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.
