• Important Use Notes & Specs: This under-sink water filter system does not reduce TDS. It is designed for municipal tap water and cold water only, and is not recommended for well water or hot water. Faucet model No. 8900; manufacturer: Qingdao Ecopure Filter Co., Ltd. Maximum flow rate: 1.45 GPM.
• Replacement Filter Options: Replacement filters for WD-TSB/WD-TSA systems include WD-10PP, WD-10GC, and WD-10CT (search by these model names for the correct match).
• Multi-Filter, Multi-Stage Filtration: Includes 3 filters for an 8-stage filtration process designed to help reduce PFAS (including PFOA/PFOS), residual chlorine, fluoride, heavy metals, silt, rust, and cysts. KDF media helps reduce heavy metals, and the 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.
• Durable, Leak-Resistant Build: Uses reinforced materials and an upgraded design. Reported testing includes 400 psi burst pressure, 100,000+ pulse tests at 150 psi, and 300 psi static tests, intended to help reduce the risk of cracking and leaking.
• Clogging Control, Lifespan & Easy Setup: An upgraded filtration area is described as providing about 20× more dirt-adhesion area to help lower clogging risk. Filter life is listed as 6 months, 8–12 months, and 12–18 months for the three filters (actual life varies by water conditions). Installs as a DIY setup with 3/8" and 1/2" cold water tubes using push-to-connect fittings (installation typically under 3 minutes), and each filter uses a twist-and-lock design for quick replacement (about 3 seconds). For trips, store used filters in sealed bags in the refrigerator (not the freezer) for up to 30 days.
