Many 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—depending on actual situations, 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 in homes. Since Americans spend an average of 90% of their time indoors, superior indoor air quality is vital for great health, regardless if it’s in our homes or our workplaces. To help manage this pollution and improve our indoor air quality, we can take different measures. But first, we must to understand some terms commonly used to discuss indoor air quality.
HEPA is a term many 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 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 filters through the system. This significantly increases your home’s indoor air quality when dust, pollen, mites and other contaminants are destroyed.
Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With metrics ranging from 1–16, you should look for a higher rating that specifies the filter will remove 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.
