The majority of people understand how detrimental outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual home can be more polluted—reliant on actual conditions, it can be up to five times more. Things have become so bad, the EPA has indoor air pollution ranked as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found inside. Since Americans spend around 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 contain this pollution and increase our indoor air quality, we can take several measures. But first, we must to understand some terms often used to discuss indoor air quality.
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 capture at least 99.97% of .3-micron particles (smaller 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 trapped.
Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With rankings ranging from 1–16, you should look for a higher rating that reveals 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.
