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 usual house might be more polluted—reliant on actual circumstances, 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 a necessity for great health, despite 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 need to absorb some lingo often used to discuss indoor air quality. HEPA HEPA is a term most 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 (less than the diameter of a human hair) from the air that moves 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 describes the effectiveness of an air filter. With metrics ranging from 1–16, you should find a top rating that indicates the filter will destroy more contaminants and allergens from your air without confining the airflow of your home comfort system. Ask us which MERV-rated filter will work best for your home. At Central Air Inc, we can help you understand the importance of indoor air quality and help you work on breathing the best air possible.
