Your home deserves to be clean and healthy. This is where you spend most of your quality time.
The MERV rating let you choose the quality of the filter you want to remove dust and mould from the air.
You should use a filter with the minimum rating of MERV 8.

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.
