What You Need to Know About Indoor Air Quality08/08/2016 Most people understand how harmful outdoor air pollution like car emissions can be, but they don’t realize that the air inside the typical living space might be more polluted—depending 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 in homes. Since Americans spend about 90% of their time indoors, superior indoor air quality is crucial for great health, regardless if it’s in our homes or our workplaces. To help handle this pollution and better our indoor air quality, we can take multiple measures. But first, we need to grasp some vernacular consistently used to discuss indoor air quality. HEPA HEPA is a term most 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 created—and certified—to capture at least 99.97% of .3-micron particles (smaller than the diameter of a human hair) from the air that filters through the system. This drastically 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 specifies 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.
