We all hear about 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 approximately 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 a few common terms traditionally used when speaking about indoor air quality, so make sure you’re familiar with these:
You’ve likely 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 goes through the system. Dust, pollen, mites and other impurities can all be captured, greatly improving your home’s indoor air quality.
MERV is a shortened version of “minimum efficiency reporting value” or put in simple terms, it says the effectiveness of your air filter. MERV ratings can be anywhere from 1-16 with the higher rating eliminating 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.
