• ‌Important Use Notes & Specs: This under-sink system does not reduce TDS. It is designed for municipal tap water and cold water only (not for well water or hot water). Faucet model No. 8900; manufacturer: Qingdao Ecopure Filter Co., Ltd. Maximum flow rate: 1.45 GPM.
• Replacement Filter Models: For WD-TSB/WD-TSA systems, compatible replacement filters include WD-10PP, WD-10GC, and WD-10CT (search by these model names).
• 3 Filters / 8-Stage Filtration: Includes 3 filters to provide 8-stage filtration designed to help reduce PFAS (including PFOA/PFOS), residual chlorine, fluoride, certain heavy metals, silt, rust, and cysts. KDF media helps reduce heavy metals, and fluoride-reduction resin is stated to reduce fluoride by up to 97%. IAPMO certification is noted for residual chlorine reduction and taste improvement; minerals may be retained, but TDS remains unchanged.
• Durability & Anti-Clog Design: Built with reinforced, age- and freeze-resistant materials. Reported testing includes 400 psi burst, 100,000+ pulse tests at 150 psi, and 300 psi static testing to support leak/crack resistance. An upgraded filtration area is described as providing about 20× more dirt-adhesion area to help reduce clogging risk.
• Lifespan & Easy DIY Setup: Filter-life guidance is 6 months, 8–12 months, and 12–18 months for the three filters (varies by water conditions). Installs as a DIY system with 3/8" and 1/2" cold-water tubes using push-to-connect fittings (typically under 3 minutes), and each filter uses a twist-and-lock design for replacement in about 3 seconds. For travel, store used filters in sealed bags in the refrigerator (not the freezer) for up to 30 days.
