We 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 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 is at home or in the office. The EPA has ranked indoor air pollution in the top five environmental concerns. A few normal 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:
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 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 heads through the system. Dust, pollen, mites and other pollutants can all be captured, greatly increasing your home’s indoor air quality.
MERV is a shortened version of “minimum efficiency reporting value” or put in easier terms, it says the effectiveness of your air filter. MERV ratings can be anywhere from 1-16 with the higher rating removing more contaminants and allergens without inhibiting the airflow of your home comfort system. We can work with you to decide on a filter with a MERV rating that will work best for your needs.
