We use some of the same factories as the top tier US filter manufacturers.Best regards,Customer Service Center **Q: How long are these supposed to last? We bought a house with this on it, and there's no Rainsoft dealer around.** A: I replace once a year. Hard to tell really. Supposed to be 5 gallons a day for a year. I don't use that much. These are less than half the price Rainsoft charges and work well. Just replace it and put the sticker on with the date and start fresh I would recommend. **Q: Is this an official rainsoft oem p-12 filter or an after market copy? will using this filter void my manufacturer warranty?** A: Hi David: As noted this is a compatible replacement and not OEM. The use of a compatible replacement does not itself void the manufacturers warranty. Thank You, WaterFiltersOnline **Q: what does this filter remove from the water?** A: Calcium build up and any sentiments in the water. --- ## 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.be/products/31988653-rainsoft-comp-p-12-hydrefiner-compatible-replacement-water-filter-cartridge](https://www.desertcart.be/products/31988653-rainsoft-comp-p-12-hydrefiner-compatible-replacement-water-filter-cartridge) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-01*
