Why it matters
The Filter King Pleated MERV 8 Air Filter is a pleated furnace and air conditioner filter rated MERV 8. Its size table lists 378 sizes in 1-inch, 2-inch, 4-inch depths, each linked to its own listing.
Sizes by depth: 1-inch: 193 sizes (from 6x12.25x1 to 30x36x1); 2-inch: 168 sizes (from 10x10x2 to 30x36x2); 4-inch: 17 sizes (from 12x20x4 to 25x25x4).
Besides Amazon, Filter King sells these sizes direct; the size table shows both where available.
MERV 8 is the common equipment-protection grade: it catches dust, lint, pollen and most pet hair with very little airflow restriction.
The listing sells it as 6 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.
The Filter King listing names 6 filters per box.
Compared with the Filter King MERV 13 1-inch Furnace Filter: MERV rating 8 here vs 13.
