Installation was fairly simple other than reaching behind the sink to install the filter faucet. I experienced no leaks but I did use plumbers tape on all the connections. HIGHLY RECOMMEND! Makes my water taste so much better but I have to say its not Poland Spring. ## Frequently Bought Together - AO Smith Under Sink Water Filter System - Reduces PFAS, Lead, & Chlorine in Drinking Water - Under Counter Claryum Filtration for Kitchen - 2-Stage - AO-US-200 - AquaBliss High Output Revitalizing Shower Filter - Reduces Dry Itchy Skin, Dandruff, Eczema, and Dramatically Improves The Condition of Your Skin, Hair and Nails - Chrome (SF100) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/145943293-ao-smith-under-sink-water-filter-system-reduces-pfas-lead](https://www.desertcart.jp/products/145943293-ao-smith-under-sink-water-filter-system-reduces-pfas-lead) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-07*
