Why it matters
The Frigidaire MERV 11 1-inch Furnace Filter is a pleated furnace and air conditioner filter rated MERV 11.
MERV 11 is the usual allergy upgrade: it catches most pollen, pet dander and mold spores, and part of the 1 to 3 micron range.
As general guidance, check a 1-inch filter monthly and change it every one to three months; deeper 4- and 5-inch filters usually last six to twelve months.
This listing is the 20x25x1 size; order by the size printed on your old filter's frame.
The Frigidaire listing names 6 filters per box.
Compared with the Frigidaire Pleated MERV 8 Air Filter: MERV rating 11 here vs 8.
