I used to have the carbon whole house water filter and I did have a drop in water pressure. I really like this whole house water filter, because it is white and it will show the contaminants in the water supply. **Q: Does the filter come with the O-Ring or should I buy that separately?** A: Buy one separately, I used the same one three filters in a row and the fourth time I couldn't make it fit. It stretched too much. **Q: What is the GPM range for the filter?** A: I don’t know the exact gallons a minute but I have a 4000 square-foot house for kids and the wife and I. We have had no problem running it in our household for 20 years ## Frequently Bought Together - AO Smith 4.5"x10" 25 Micron Sediment Water Filter Replacement Cartridge - For Whole House Filtration Systems - AO-WH-PREL-R - AO Smith 4.5"x10" 5 Micron Carbon Sediment Water Filter Replacement Cartridge - For Whole House Filtration Systems - AO-WH-PREL-RCP - AO Smith 4.5"x10" 25 Micron Carbon Sediment Water Filter Replacement Cartridge - For Whole House Filtration Systems - AO-WH-PREL-RC --- ## 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.com.au/products/165123625-4-5-universal-sediment-filter](https://www.desertcart.com.au/products/165123625-4-5-universal-sediment-filter) --- *Product available on Desertcart Australia* *Store origin: AU* *Last updated: 2026-08-27*
