What You Need to Know About Indoor Air Quality08/08/2016 Many 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 home can be more polluted—contingent on actual situations, it can be up to five times more. Things have become so damaging, 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 crucial for good health, regardless if it’s in our homes or our workplaces. To help handle this pollution and increase our indoor air quality, we can take several measures. But first, we are required to absorb some terms often used to discuss indoor air quality. HEPA HEPA is a term many 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 (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 captured. MERV Minimum efficiency reporting value or MERV expresses the effectiveness of an air filter. With rankings ranging from 1–16, you should pursue a higher rating that specifies the filter will filter more contaminants and allergens from your air without limiting the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home.
