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—depending on actual circumstances, it can be up to five times more. Things have become so bad, 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, good indoor air quality is crucial for decent health, despite if it’s in our homes or our workplaces. To help manage this pollution and improve our indoor air quality, we can take several measures. But first, we are required to absorb some terms consistently 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 designed—and certified—to capture at least 99.97% of .3-micron particles (less 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 destroyed.
Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With rankings ranging from 1–16, you should look for a max rating that reveals the filter will destroy 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.
