Our take on the K&N 24-in W x 24-in L x 1-in Washable MERV 8 Pleated Air Filter HVC-8-12424

This is a 24 x 24 x 1 inch pleated HVAC filter from K&N, the company known for reusable engine air filters. It is washable and rated MERV 8, so it traps dust, pollen and lint but not fine smoke or virus particles. The only new price found is $49.99 at Lowe's as of November 7, 2026, with no other store competing on it. That is high for a single filter, so the value depends on how many disposable filters it replaces over its life.

Best forHomeowners tired of buying disposable filters every few monthsStandard 24x24x1 return grilles and furnace slotsDust and pollen control in typical homesPeople who want to rinse a filter instead of trashing it
Pros
  • Washable and reusable, so one purchase replaces many disposables
  • MERV 8 captures dust, pollen and lint for most homes
  • Rigid pleated frame holds shape through rinsing
  • Exact 24 x 24 x 1 fit for common return grilles
  • K&N has a long track record with reusable filters
Cons
  • $49.99 for one filter is several times the price of a disposable MERV 8
  • MERV 8 will not satisfy smoke, pet dander or allergy sufferers wanting MERV 11 or higher
  • Needs regular washing and full drying before reinstall
  • Wet or damp reinstallation can promote mold and airflow problems
  • Only one store prices it new, so there is little price competition

What reviewers say

Owners of washable K&N filters generally report solid dust capture and years of reuse, which offsets the upfront cost. Complaints center on the higher price and the chore of washing and drying.

What people mention

Questions and answers

Is this filter worth $49.99?
Only if you would otherwise buy several disposable filters a year. At $49.99 at Lowe's as of November 7, 2026, it needs to replace roughly a year or more of disposables to break even.
How often should I wash it?
K&N generally suggests rinsing every one to three months depending on dust and pets. Let it dry completely before putting it back.
Is MERV 8 enough for allergies?
MERV 8 catches dust, pollen and lint but not fine smoke or most bacteria. Households with allergy sufferers often want MERV 11 or higher.
Will it fit my 24x24x1 slot?
Yes, it is built to the nominal 24 x 24 x 1 size. Measure your slot first, since actual filter dimensions can run slightly under nominal.
Does a washable filter restrict airflow more?
A clean MERV 8 pleated filter is comparable to a disposable of the same rating. A dirty or damp one will restrict airflow, so keep it clean and dry.
When is it cheapest?
Only Lowe's listed a new price, $49.99, as of November 7, 2026. Watch for seasonal HVAC sales and multi-packs, which lower the per-filter cost.
Where is the K&N 24-in W x 24-in L x 1-in Washable MERV 8 Pleated Air Filter HVC-8-12424 cheapest?
At Lowe's, for $49.99, as of our latest check.
