• ‌Important Use Notes (TDS & Water Source): This under-sink 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.
• Replacement Filter Models (No ASIN): For the WD-TSB-ALK system, replacement filters include WD-10PP, WD-10GC, and WD-10ALK (search by these model names).
• Alkaline Mineral Enrichment: The alkaline stage is designed to add minerals such as calcium, magnesium, sodium, and potassium to help enhance taste; mineral retention/addition may keep TDS readings from dropping.
• 8-Stage Filtration (3 Filters): Includes 3 filters to provide 8-stage filtration (including alkaline filtration) and is third-party tested to help reduce chlorine, taste & odor, fluoride, certain heavy metals, rust, sediment, sand, and particles. KDF media helps reduce heavy metals, and ion-exchange resin supports fluoride reduction.
• Easy Install, Lifespan & Anti-Clog Design: Twist-and-lock design supports DIY installation in about 3 minutes and filter changes in about 3 seconds. Filters are rated for up to 12 months of use (varies by water conditions). For vacations, store used filters in sealed bags in the refrigerator (not the freezer) for up to 30 days. An upgraded filtration area is described as providing about 20× more dirt-adhesion area to help reduce clogging risk and support consistent performance.
