What You Need to Know About Indoor Air Quality08/08/2016We all hear about the dangers of outdoor air pollution, such as car emissions. What a lot of people don’t realize is that the air inside the regular home is approximately five times more polluted than outside air. Indoor air quality is important because Americans spend approximately 90% of their time indoors, whether it is at home or running errands. The EPA has ranked indoor air pollution in the top five environmental hazards. Some common indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also a couple common terms normally used when speaking about indoor air quality, so make sure you understand these: HEPA You’ve probably seen or heard this term used, but do you know what it means? HEPA stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”. HEPA filtration systems are manufactured and certified to capture at least 99.97% of .3-micron (.000012” or 300x smaller than the diameter of human hair) particles from the air that passes through the system. Dust, pollen, mites and other impurities can all be captured, greatly boosting your home’s indoor air quality. MERV MERV is short for “minimum efficiency reporting value” or put in simpler terms, it states the effectiveness of your air filter. MERV ratings can range from 1-16 with the higher rating getting rid of more contaminants and allergens without impacting the airflow of your home comfort system.
