- Is a MERV 8 filter enough for allergies?
- MERV 8 catches dust, pollen and lint, which suits most homes. For pet dander, smoke or serious allergies, a MERV 11 to 13 pleated filter is the better choice.
- How often should I wash it?
- Rinse it every 1 to 3 months, or sooner in dusty homes or with pets. Let it dry completely before putting it back in the grille.
- Does washing ruin the electrostatic charge?
- The charge fades with each wash, so the filter gets less effective over time. Expect to replace it after roughly a year of regular cleaning.
- Will it fit my 10 x 20 return grille?
- It is a nominal 10 x 20 x 1 filter, so it fits standard grilles of that size. Measure the opening, not the old filter, before ordering.
- Is the 10-pack a good deal?
- At $23.55 at Lowe's as of November 7, 2026, it is about $2.36 per filter, far below disposable pleated filters. The catch is that reusable filters need washing and wear out.
- Does a MERV 8 filter strain the HVAC system?
- MERV 8 is low-restriction and generally safe for most systems. Check that airflow at your vents does not drop after installing it.
