This improves your air's humidity to support good sleep, healthy sinuses, and a happier home for you and your loved ones. **Q: Which humidifiers does this fit?** A: Our premium HAC-504 filters are compatible with Honeywell HCM-350, HEV-355, HCM-710, HCM-315, HEV-312 and many other HCM and HEV series models. **Q: How often do I need to replace my filter?** A: Replace your filter once it begins to harden and/or yellow. Hard tap water means it has more minerals. Your filter absorbs these minerals and will shorten the life of your filter versus a household with access to soft water. **Q: How can I maximize the life of my filter?** A: While not necessary, you can maximize the life of your filter by using distilled, bottled water or filtered water from your tap. Additionally, flip your filter over daily to ensure the entire filter stays moist. **Q: How do I install a new filter?** A: We recommend pre-moistening the filter by running it under water until it is soaked though. Once soaked, remove the cover of your machine, take out the old filter, and replace it with the new, pre-soaked filter. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very efficient-good value *by R***H on December 14, 2025* My humidifier won't work without these filters.

Good quality filters. ### ⭐⭐⭐⭐⭐ Air filters are awesome *by A***R on October 2, 2026* I order these from every time I need filters for my room humidifier. They are perfect! ### ⭐⭐⭐⭐ decent replacement filter *by A***A on January 26, 2026* The filters are the correct size as the original, although thinner. They function as expected. They don't wear as well as the brand name that came with the humidifier but are a decent substitute for the price. ## Frequently Bought Together - Durabasics 4 Pack of Premium Humidifier Filters Compatible with Honeywell Humidifier Filters HAC-504, HAC-504AW & Honeywell Filter A | Replacement for HCM 350 Filters & Cool Mist Humidifiers - Protec Humidifier Tank Cleaner, 1 Count - Colors May Vary - ProTec PC-2 Humidifier Tank Cleaning Cartridge, 2-Count Packages (1 pack of 2 cartridges) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/64283583-durabasics-4-pack-of-premium-humidifier-filters-compatible-with-honeywell](https://www.desertcart.jp/products/64283583-durabasics-4-pack-of-premium-humidifier-filters-compatible-with-honeywell) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-30*
