Things have become so bad, the EPA has indoor air pollution ranked as a top five environmental danger. Mold, pollen, pet dander, radon and even formaldehyde are commonly found indoors. Since Americans spend around 90% of their time indoors, superior indoor air quality is a necessity for great health, despite if it’s in our homes or our workplaces.

HEPA HEPA is a term many people have heard or seen, but did you realize it stands for “high-efficiency particulate air” or “high-efficiency particulate arrestance”?

This drastically increases your home’s indoor air quality when dust, pollen, mites and other contaminants are captured. MERV Minimum efficiency reporting value or MERV describes the effectiveness of an air filter. With ratings ranging from 1–16, you should find a top rating that indicates the filter will filter more contaminants and allergens from your air without restricting the airflow of your home comfort system.
