Our take on the K&N 18 x 30 x 1 Washable MERV 8 Pleated Air Filter HVC-8-11830

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.

Questions and answers

K&N rates it for about three months between cleanings. Rinse it, let it dry fully, then reinstall.

Does it work with air conditioners?
Yes. It is made for AC and furnace returns.
What does the warranty cover?
K&N offers a limited lifetime warranty on the filter.
