What You Need to Know About Indoor Air Quality08/08/2016We all know the dangers of outdoor air pollution, such as car emissions. What a lot of people don’t know is that the air inside the average home is around five times more polluted than outside air. Indoor air quality is important because Americans spend nearly 90% of their time indoors, whether it’s at home or running errands. The EPA has ranked indoor air pollution in the top five environmental hazards. A few normal indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also some common terms regularly used when discussing indoor air quality, so make sure you understand these: HEPA You’ve likely seen or heard this term used, but do you understand 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 heads through the system. Dust, pollen, mites and other pollutants can all be captured, greatly boosting your home’s indoor air quality. MERV MERV is an acronym for “minimum efficiency reporting value” or put in simple terms, it tells you the effectiveness of your air filter. MERV ratings can be anywhere from 1-16 with the higher rating getting rid of more contaminants and allergens without impacting the airflow of your home comfort system.
