Indoor Air Quality IAQ is very important to all of us.  What is MERV?  (Minimum Efficiency Reporting Value)
A Typical Fiberglass Filter which is installed with your furnace when you bought your new home = MERV 1
MERV is the measurement the industry uses to describe the filters' ability to capture particles floating around the air in your home.
The higher the MERV rating, the smaller the particles captured, which means enhanced filtration or cleaner air for your home.
Here is an example of Pollutant sizes of the air we breathe, to determine the quality of air that's acceptable for your own family.
* Small breathable particles (0.5 to 100 microns) * Airborne mold spores, bacteria and viruses (0.01 to 50 microns)
* Odors/Chemical vapors (0.01 to 1 micron) * One Micron = 1/25,000 of an inch in diameter.
Genuine Lennox Furnace Filter removes small, breathable particles,
airborne Mold and other Bioaerosols as small as 0.3 Micron.
HEPA Hi-Efficiency Particulate Air Bypass Filtration System is up to 99.97% efficient in removing particles and Bioaerosols.
