Better filtration is an important step in improving indoor air quality. Dust, pollens, mold spores, animal dander, carpet lint, bacteria, rubber and dust mite feces are some of the things we inhale. This results in sinus congestion, sore throats, asthma, allergies and many other symptoms.
MERV Standards for Minimum Efficiency Reporting Value. The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) assigns a MERV number intended to help people compare filters. The MERV efficiency rating is the filters ability to capture specific micron particles. The higher the MERV rating, the better the filtration.
