Our Waterdrop under-sink system keeps these beneficial minerals in your water while filtering out the nasty stuff you don’t want. Quick note: Our activated carbon is made from natural coconut shells. So if coconuts aren’t your thing, double-check before you get filtering! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0D1R92FPJ | | Best Sellers Rank | #101,963 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #158 in Under-Sink & Countertop Filtration | | Brand Name | Waterdrop | | Capacity | 8000 gallons | | Container Type | Box | | Customer Reviews | 4.4 4.4 out of 5 stars (132) | | Filter Life Cycle | 12 months | | Global Trade Identification Number | 06922350619616 | | Included Components | System×1, Faucet x 1, 3/8"–1/2" Convertor set×1, Accessory Kit×1, hose×2 | | Installation Type | Under Sink | | Item Dimensions L x W x H | 12.9"L x 4.3"W x 12.4"H | | Item Highlight | Reduces PFAS, PFOA/PFOS, Fluoride, Chlorine, Bad Taste & Odor, with Dedicated Faucet, Under Sink Water Filtration System | | LowerTemperature Range | 35 °F | | Manufacturer | Waterdrop | | Material Type | NSF/ANSI Approved Components | | Maximum Flow Rate | 1.5 gpm | | Model Name | WD-TSB-ALK | | Model Number | WD-TSB-ALK | | Number of Items | 1 | | Number of Packs | 1 | | Other Special Features of the Product | Alkaline under sink water filter system add beneficial minerals, enhance taste, promote health, and strengthen bone strength. | | Part Number | WD-TSB-ALK | | Power Source | Mechanical Water Pressure | | Product Shelf Life | 12 months | | Purification Method | Alkaline | | Supported Water TDS Level Maximum (PPM) | 700 | | Unit Count | 1 Count | | Upper Temperature Rating | 100 °F | | Warranty Description | 1 Year Manufacturer | ## Product Details - **Brand:** Waterdrop - **Capacity:** 8000 gallons - **Included Components:** System×1, Faucet x 1, 3/8"–1/2" Convertor set×1, Accessory Kit×1, hose×2 - **Installation Type:** Under Sink - **Material:** NSF/ANSI Approved Components - **Package Information:** Box - **Power Source:** Mechanical Water Pressure - **Product Dimensions:** 12.9"L x 4.3"W x 12.4"H - **Purification Method:** Alkaline ## Images ![Waterdrop TSB-ALK Slightly Alkaline 8 Layer Under Sink Water Filter System - Image 1](https://m.media-amazon.com/images/I/71fyN7CaHrL.jpg) ![Waterdrop TSB-ALK Slightly Alkaline 8 Layer Under Sink Water Filter System - Image 2](https://m.media-amazon.com/images/I/41azchmirXL.jpg) ![Waterdrop TSB-ALK Slightly Alkaline 8 Layer Under Sink Water Filter System - Image 3](https://m.media-amazon.com/images/I/518H6xcogeL.jpg) ![Waterdrop TSB-ALK Slightly Alkaline 8 Layer Under Sink Water Filter System - Image 4](https://m.media-amazon.com/images/I/5199dtrbI2L.jpg) ![Waterdrop TSB-ALK Slightly Alkaline 8 Layer Under Sink Water Filter System - Image 5](https://m.media-amazon.com/images/I/51gkPG4AxFL.jpg) ## Frequently Bought Together - Waterdrop TSB-ALK 8 Layer High Capacity Slightly Alkaline Under Sink Water Filter, Reduces PFAS, PFOA/PFOS, Fluoride, Chlorine, Bad Taste & Odor, with Dedicated Faucet, Under Sink Water Filter - Waterdrop TSA 3-Stage Replacement Water Filter, Replacement for Waterdrop TSA & TSB & TSB-CM 3-stage Under Sink Water Filtration System, 2PP+GC - Waterdrop WD-10ALK Under Sink Water Filter, Replacement for Waterdrop TSB-ALK 8 Layer High Capacity Alkaline Under Sink Water Filtration System --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/642213532-waterdrop-tsb-alk-slightly-alkaline-8-layer-under-sink-water](https://www.desertcart.be/products/642213532-waterdrop-tsb-alk-slightly-alkaline-8-layer-under-sink-water) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-10-28*
