16 x 25 x 4 Air Filters
This collection carries the 3M Filtrete 1550 Allergen, Bacteria & Virus air filter in the 16x25x4 size, sold as a 4-pack. It's made for HVAC systems with a 4-inch media cabinet, including Honeywell, Carrier, and Bryant media air cleaners. A 4-inch cabinet needs a full 4-inch filter; a thinner one leaves gaps that let air bypass the media, which reduces filtration and can strain your blower over time.
The Filtrete 1550 is rated MERV 12, so it captures fine particles like pet dander, mold spores, smoke, and bacteria along with everyday dust, lint, and pollen. Thanks to its deep pleats, each filter lasts up to 12 months.
