The MERV 11 rebate filter will effectively remove more than 85 percent of particulate debris between 3 and 10 microns from the air passing through it. In addition, it will remove between 64 and 79.9 percent of particles that measure between 1 and 3 microns.The performance of this discount filter is based on the international industry standard Minimum Efficiency Report Value (MERV) rating. Filters with a higher rating demonstrate the ability to remove a higher proportion of particles from circulating air.

Discount filters are tested according to how efficiently they capture particles that measure between 3 and 10 microns. They are effective in keeping the air clean, but households that include people who experience particularly severe asthmatic or allergic reactions may find a higher MERV rating more suitable for providing an ideal indoor environment. MERV 11 air filters block at least 65% to 79% of particles in the air in the 1.0 to 3.0 micron size range. This rating system is based on a scale of 1 to 16, which indicates efficiency and the degree to which the filter can trap contaminants in the air. For reference, a single human hair ranges from 20 to 40 microbes in size, while viruses, the smallest microbes in the air, range from 0.1 to 0.3 microns. MERVs 14 to 20 are best for hospital and laboratory applications where as much of the air needs to be captured as possible.

Using an oven filter with a MERV rating higher than your use case requires can have adverse effects. The MERV 11 filter is best for pet owners and people living with certain health conditions, such as mild allergies and mild asthma.
