holmes water filter

The product description says a reinforced mesh design captures hard minerals from the water, helping prevent mineral "white dust" from circulating in indoor air.

Listings recommend replacing the filters every 2–3 months and suggest using distilled water for best results.

Most listings show dimensions of 4.5 in (H) x 1.3 in (W) x 6.7 in (D); one listing shows a depth of 8.1 in. Because dimensions vary between listings, check the specific product listing to confirm fit for your humidifier model.

According to the listings, the filters capture lint, pollen, smog, household dust and odors, and the descriptions also note they capture hard minerals from water.

The listings offer packs of 2, 4, and 8 replacement filters.
