Amazon Basics MERV 5 Furnace Air Filter: MERV 5

Why it matters

The Amazon Basics MERV 5 Furnace Air Filter is a pleated furnace and air conditioner filter rated MERV 5.

MERV 5 is a basic dust-and-lint grade: it protects the blower and coil but does little for fine particles.

The listing sells it as 6 filters per pack; the material is cardboard.

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 20x20x1 size; order by the size printed on your old filter's frame.

The Amazon Basics listing names 6 filters per box.

Compared with the Amazon Basics MERV 11 1-inch Furnace Filter: MERV rating 5 here vs 11.

Questions buyers ask

Is MERV 5 right for my home?

MERV 5 is a basic dust-and-lint grade: it protects the blower and coil but does little for fine particles. 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.
