It works on water pressure alone. **Q: How much water pressure is required for it to work?** A: The feed water pressure should be: 30-70 psi **Q: How long do the filters last before needing replacement?** A: The filters should be replaced every 6 to 12 months, depending on usage and water quality. This ensures optimal performance and water quality. **Q: Will it reduce TDS?** A: No, this under-sink water filtration system does not reduce TDS levels. Instead, it maintains the TDS of the incoming water, preserving essential minerals. If TDS reduction is necessary, we recommend considering an iSpring reverse osmosis system. ## Frequently Bought Together - iSpring US31 Classic 3-Stage Under Sink Water Filtration System for Drinking, Tankless, High Capacity, Sediment + GAC + Carbon - iSpring F7-GAC NSF Certified 1-Year Replacement Filter Cartridge Pack, 7-Count for Standard 5-Stage Reverse Osmosis (RO) Systems - iSpring FA15 Alkaline Inline Water Filter Cartridge, 10” x 2” with 1/4” Quick Connect, NSF Certified, Add-on for RO Systems, Balances pH & Restores Minerals, 3-Layer Replacement Filter --- ## 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://grenada.desertcart.com/products/70011705-us31-3-stage-under-sink-water-filter-system-with-faucet](https://grenada.desertcart.com/products/70011705-us31-3-stage-under-sink-water-filter-system-with-faucet) --- *Product available on Desertcart Grenada* *Store origin: GD* *Last updated: 2026-08-24*
