What You Need to Know About Indoor Air Quality08/08/2016 Many people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the usual house 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 tiered as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found inside. Since Americans spend an average of 90% of their time indoors, excellent indoor air quality is a necessity for good health, despite if it’s in our homes or our workplaces. To help handle this pollution and better 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 a lot of 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 designed—and certified—to confine at least 99.97% of .3-micron particles (tinier 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 captured. MERV Minimum efficiency reporting value or MERV refers to the effectiveness of an air filter. With metrics ranging from 1–16, you should pursue a max 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 Air-Dynamics Inc, we can help you understand the importance of indoor air quality and help you work on breathing the best air possible.
