I think it is pretty much sediment. **Q: When should I change the O ring** A: On average at least every 60-90 days if you notice a drop in pressure that’s a sure time your filter is do for a change out. Also will depend on your over all water quality and how much sediment comes in off your lines. **Q: Does it lower tds levels? i have 431 tds** A: Assuming TDS meant “total dissolved solids” the answer would be no. This is a sediment filter only and will not remove anything already in solution. **Q: Is this 5 or 20 micron? Both are listed. Does same filter work for PRE and POST?** A: If it says 5 micron I guess it’s 5 micron ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great fit *by on Reviewed in the United States July 11, 2026* This is my go to water filter. Always works great, easy to change. And delivered quickly through Amazon. ### ⭐⭐⭐⭐⭐ Satisfactory *by on Reviewed in the United States July 18, 2026* Product gets the job done. ### ⭐⭐⭐⭐⭐ Cleaner water *by on Reviewed in the United States February 28, 2025* Our well water is extremely mineral laden (app 500 TDS). Installed a filter in line from well to house which uses these filters. They are changed monthly and yikes - black from minerals in 4 weeks. Easily changed but have to really push them in or we get a bit of leakage which stops in a few minutes. We notice an improvement in flow as soon as we do the monthly filter change so the quality is there. The price has gone up but still very much worth it for cleaner water! ## Frequently Bought Together - AO Smith 2.5"x10" 5 Micron Sediment Water Filter Replacement Cartridge - 2 Pack - For Whole House Filtration Systems - AO-WH-PREV-R2 - AO Smith 2.5"x10" 5 Micron Carbon Wrap Sediment Water Filter Replacement Cartridge - 2 Pack - For Whole House Filtration Systems - AO-WH-PRE-RCP2 - AO Smith 2.5"x10" 5 Micron Carbon Block Sediment Water Filter Replacement Cartridge - 2 Pack - For Whole House Filtration Systems - AO-WH-PRE-RC2 --- ## 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.hk/products/123714819-a-o-smith-2-5x10-5-micron-universal-sediment-filter](https://www.desertcart.hk/products/123714819-a-o-smith-2-5x10-5-micron-universal-sediment-filter) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-08-03*
