• ‌Important Use Notes & Faucet Fit: This under-sink system does not reduce TDS and is intended for municipal tap water and cold water only (not for well water or hot water). It fits faucets with 1/2" or 3/8" female NPT threads. If you need to connect to a quick-connect faucet, compatible connection fittings can be provided upon request.
• Replacement Filter Models: For WD-TSA-UF/WD-TSB-UF systems, replacement filters include WD-10PP, WD-10GC, and WD-10UF (search by these model names).
• 0.01 μm UF + 9-Stage Filtration: Includes 3 filters to deliver 9-stage filtration. Third-party testing indicates it helps reduce chlorine, taste & odor, fluoride, certain heavy metals, rust, sediment, sand, and particles. KDF media helps reduce heavy metals, ion-exchange resin supports fluoride reduction, and the 0.01 μm ultrafiltration stage is designed to help reduce very fine impurities while improving taste.
• Filter Life & Storage Tip: Lifespan guidance: PP up to 6 months, GC about 8–12 months, and UF up to 12 months (varies by water conditions and usage). For vacations, store used filters in sealed bags in the refrigerator (not the freezer) for up to 30 days.
• Easy Install, Anti-Clog & Durability: Twist-and-lock design supports DIY installation in about 3 minutes and filter changes in about 3 seconds. An upgraded filtration area is described as providing about 20× more dirt-adhesion area to help reduce clogging risk. Built with reinforced materials intended to resist aging/freezing and support leak- and crack-resistant performance under normal operating conditions.
