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 typical home can be more polluted—contingent on actual conditions, 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 indoors. Since Americans spend about 90% of their time indoors, superior indoor air quality is crucial for good health, regardless if it’s in our homes or our workplaces. To help handle this pollution and increase our indoor air quality, we can take different measures. But first, we must to understand some vernacular often used to discuss indoor air quality. HEPA HEPA is a term a lot of 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 (smaller 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 trapped. MERV Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With rankings ranging from 1–16, you should pursue a top rating that reveals the filter will remove more contaminants and allergens from your air without limiting the airflow of your home comfort system.
