What You Need to Know About Indoor Air Quality

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 regular 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 dangers. A few common indoor pollutants include: mold, pollen, pet dander, radon and even formaldehyde. There are also some common terms normally used when speaking about indoor air quality, so make sure you understand these:

HEPA

You’ve probably 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 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

MERV is a shortened version of “minimum efficiency reporting value” or put in simple terms, it states the effectiveness of your air filter. MERV ratings can be between 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 decide on a filter with a MERV rating that will work best for your system.
