What You Need to Know About Indoor Air Quality08/08/2016 Most people are aware of how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average living space might be more polluted—depending on actual circumstances, it can be up to five times more. Things have become so bad, 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 around 90% of their time indoors, superior indoor air quality is crucial for decent health, despite if it’s in our homes or our workplaces. To help contain this pollution and improve our indoor air quality, we can take multiple measures. But first, we are required to absorb some vernacular often used to discuss indoor air quality. HEPA HEPA is a term most people have heard or seen, but did you realize 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 passes through the system. This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With ratings ranging from 1–16, you should look for a top rating that reveals the filter will filter more contaminants and allergens from your air without confining the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
