The K&N HVC-8-11830 is a washable pleated HVAC filter rated MERV 8, sized for 18 x 30 x 1 inch return grilles. It captures dust, lint, pollen, mold spores and dust mite debris, and K&N rates it for about three months between cleanings. The washable design means one filter replaces a stack of disposable pleated filters over its life, and K&N backs it with a limited lifetime warranty. Against disposable MERV 8 filters it trades a higher upfront cost for reuse; against washable electrostatic pads it offers a sturdier pleated frame and a defined MERV rating.

Owners of K&N washable filters generally report they clean up well and cut down on disposable filter purchases. Some note the filter needs a thorough rinse and dry time, and a few find the MERV 8 rating modest for allergy relief.
