Why it matters
The Nordic Pure Pleated MERV 8 Air Filter is a pleated furnace and air conditioner filter rated MERV 8 (MPR 800 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: 25 sizes (from 12x12x1 to 24x30x1); 2-inch: 4 sizes (from 16x20x2 to 20x25x2); 4-inch: 4 sizes (from 16x20x4 to 20x25x4); 5-inch: 2 sizes (from 16x25x5 to 20x25x5).
Besides Amazon, Nordic Pure 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 2 filters per pack; the material is electrostatically charged synthetic pleated media.
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 Nordic Pure listing names 2 filters per box.
Compared with the Nordic Pure 4-Inch Pleated MERV 12 Air Filter: MERV rating 8 here vs 12; MPR 800 here vs 1500.
