Why it matters
The Simply MERV 13 1-inch Furnace Filter is a pleated furnace and air conditioner filter rated MERV 13.
MERV 13 is the highest grade most homes use: it catches a good share of fine particles (0.3 to 1 micron), including much wildfire smoke, but adds more airflow resistance, especially in 1-inch frames.
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 12x12x1 size; order by the size printed on your old filter's frame.
The Simply listing names 6 filters per box.
Compared with the Simply Pleated MERV 8 Air Filter: MERV rating 13 here vs 8.
