What You Need to Know About Indoor Air Quality08/08/2016 Many people are aware of how dangerous outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical living space often is more polluted—reliant on actual circumstances, 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 in homes. Since Americans spend an average of 90% of their time indoors, good indoor air quality is vital for great health, despite if it’s in our homes or our workplaces. To help contain this pollution and improve our indoor air quality, we can take several measures. But first, we need to absorb some lingo commonly used to discuss indoor air quality. HEPA HEPA is a term a lot of 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 capture at least 99.97% of .3-micron particles (smaller 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 expresses the effectiveness of an air filter. With rankings ranging from 1–16, you should pursue a max 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.
