What You Need to Know About Indoor Air Quality08/08/2016 The majority of people are aware of how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the average living space can be more polluted—depending 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 in homes. Since Americans spend about 90% of their time indoors, excellent indoor air quality is a necessity for decent health, no matter if it’s in our homes or our workplaces. To help handle this pollution and better our indoor air quality, we can take multiple measures. But first, we need to grasp some terms 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 significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured. MERV Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With ratings ranging from 1–16, you should look for a top rating that indicates the filter will filter 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.
