What You Need to Know About Indoor Air Quality08/08/2016 Most people realize how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual house might be more polluted—contingent on actual situations, it can be up to five times more. Things have become so damaging, 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 about 90% of their time indoors, superior indoor air quality is crucial for great health, regardless if it’s in our homes or our workplaces. To help contain this pollution and better our indoor air quality, we can take multiple measures. But first, we need to absorb some terms consistently 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 designed—and certified—to confine at least 99.97% of .3-micron particles (tinier 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 refers to the effectiveness of an air filter. With metrics ranging from 1–16, you should pursue a top rating that indicates 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.
