Why it matters

The Filtrete MPR 1000 (MERV 11) Air Filter is a pleated furnace and air conditioner filter rated MERV 11 (MPR 1000 on the 3M scale). Its size table lists 35 sizes in 1-inch, 2-inch, 4-inch, 5-inch depths, each linked to its own listing.

Sizes by depth: 1-inch: 30 sizes (from 12x12x1 to 20x36x1); 2-inch: 2 sizes (from 16x20x2 to 20x20x2); 4-inch: 1 sizes (from 20x25x4 to 20x25x4); 5-inch: 2 sizes (from 16x25x5 to 20x25x5).

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.

The listing sells it as 2 filters per pack; the material is polypropylene.

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.

Compared with the Filtrete MPR 1500 (MERV 12) Air Filter: MERV rating 11 here vs 12; MPR 1000 here vs 1500.

Questions buyers ask

Is MERV 11 right for my home?
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. If your system is old or the filter slot is a 1-inch return grille, watch for whistling or a filter that bows; those are signs to step down a grade.
