What You Need to Know About Indoor Air Quality08/08/2016 Many people are aware of 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 classified 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, excellent indoor air quality is vital for decent 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 are required to understand some vernacular consistently 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 confine 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 significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are trapped. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With rankings ranging from 1–16, you should pursue a higher rating that specifies 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.
