What You Need to Know About Indoor Air Quality08/08/2016We all recognize the dangers of outdoor air pollution, such as car emissions. What a lot of people don’t recognize is that the air inside the normal home is nearly five times more polluted than outside air. Indoor air quality is important because Americans spend nearly 90% of their time indoors, whether it is at home or in a store. The EPA has ranked indoor air pollution in the top five environmental dangers. Some common indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also a couple common terms traditionally used when speaking about indoor air quality, so make sure know about these: HEPA You’ve possibly 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 produced 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 goes through the system. Dust, pollen, mites and other contaminants can all be captured, greatly increasing 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 eliminating more contaminants and allergens without impacting the airflow of your home comfort system. We can work with you to determine a filter with a MERV rating that will work best for your home. We breathe on average 11,000 liters of air a day.
