Top Of The Line Filters....  Even The MERV 8 has the latest "State Of The Art" design, like:

  • Better Quality - 30 Gauge Galvanized Expanded Metal Grid.

  • Moisture Resistance 28 Point Beverage Board Frame.

  • Filtering Media 100% Bonded To Frame.

  • Resist Moisture To 100% RH.

Filter Particulate Removal Efficiency Rating:
MERV-8:  GOOD
MERV-11: BETTER

MERV-13: EXCELLENT

CARBON: Removes Foul Odors and

Particulate Removal rated GOOD


Simply stated, the higher the MERV number, the more efficient the air filter will be in removing contaminants and pollutants from the airflow in your home or office. 
A MERV 13 air filter is more than twice as efficient as a MERV 8 in removing contaminants 1 micron in size.  To understand how small 1 micron is, a human hair measures 100 microns. Finally, keep in mind that the MERV rating has nothing to do with size. MERV 8 and MERV 11 and MERV 13 are all the same size air filters for any given model number.
