We all recognize 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 approximately 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 dangers. Some common indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also a couple common terms traditionally used when discussing indoor air quality, so make sure you understand these:
You’ve likely seen or heard this term used, but do you grasp 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 passes through the system. Dust, pollen, mites and other impurities can all be captured, greatly increasing your home’s indoor air quality.
MERV is short for “minimum efficiency reporting value” or put in simpler terms, it states 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 inhibiting 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 needs.
We breathe on average 11,000 liters of air a day. We want to help you realize the importance of indoor air quality and help be sure the air in your home is good for your health.
