Review: Buy with confidence - customer Service had my back! - Buy with confidence! Let's face it, we all have better things to do than lug around flats of water bottles. And all the time having that nagging thought of where these bottles have been? Heated and cooled through the delivery - microplastics, and how many bottles have I contributed to landfills? Well, I am happy to say that making sure I have clean, filtered water is as easy as turning on the tap - just like the old days! LOL! I rested the unit on the bottom of the cabinet - easy to disengage and replace the filters. The unit was super easy to hook up. I had one unit professionally installed and one I did myself. The instructions are so straightforward. The water is even more clean-tasting (if that makes sense) than any bottled water (aside from the super expensive one in a glass - but maybe it's equal or better), it comes out cold and perfect! I had a glitch with one of the units, and had the chance to work with the Customer Service, shoutout to Kimberly and Reanne - they were responsive and walked me through the process and quickly offered a solution - including the replacement of one unit. ## Features - [Important Note] This under sink water filter system does NOT reduce TDS. It is specifically designed for municipal tap water and can only be used with cold water sources. This water filter for sink faucet is not suitable for well water or hot water - [Replacing your filter? ] To replace the filter for your WD-TSB-ALK under-sink water filtration system, Please search for B0CM8MHWNT for the WD-10PP filter, B0CM8KV1M9 for the WD-10GC filter, B0D1R69QQS for the WD-10ALK filter. - [Fantastic Taste, Better Health] This alkaline under sink water filter system enriches your tap water with beneficial minerals such as calcium, magnesium, sodium, and potassium, enhancing its taste.

Note: Do not reduce TDS. - [8-stage Advanced Filtration] This under sink water filtration system includes 3 filters for 8-stage deep filtration, including alkaline filtration, to reduce chlorine, taste and odor, fluorides, heavy metals, rust, sediment, sand and particles, tested by a third-party lab.

This system is designed for Municipal Tap Water. If using well water as the source, please make sure the feed water has been through a pre-filtration system. For the solution with a pre-filtration system, please search for WD-PFK. - [TDS & WATER QUALITY] Heads up — TDS meters aren’t the be-all and end-all of water quality. Why? ‘Cause essential minerals like calcium, potassium, sodium, and magnesium are dissolved solids too. That means your TDS reading might not budge, and that’s actually a good thing! 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 | #10,372 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #26 in Under-Sink & Countertop Filtration | | Brand | Waterdrop | | Brand Name | Waterdrop | | Capacity | 8000 gallons | | Container Type | Box | | Customer Reviews | 4.4 out of 5 stars 1,509 Reviews | | EU Spare Part Availability Duration | 1 years | | 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 | NSF/ANSI Approved Components | | 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 | | 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 Dimensions | 12.9"L x 4.3"W x 12.4"H | | 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 8 Layer Slightly Alkaline Under Sink Water Filter System - Image 1](https://m.media-amazon.com/images/I/71fyN7CaHrL.jpg) ![Waterdrop TSB-ALK 8 Layer Slightly Alkaline Under Sink Water Filter System - Image 2](https://m.media-amazon.com/images/I/81myCTLl0HL.jpg) ![Waterdrop TSB-ALK 8 Layer Slightly Alkaline Under Sink Water Filter System - Image 3](https://m.media-amazon.com/images/I/81gsTwuoEzL.jpg) ![Waterdrop TSB-ALK 8 Layer Slightly Alkaline Under Sink Water Filter System - Image 4](https://m.media-amazon.com/images/I/81VR4ITIOXL.jpg) ![Waterdrop TSB-ALK 8 Layer Slightly Alkaline Under Sink Water Filter System - Image 5](https://m.media-amazon.com/images/I/817+7c1wi6L.jpg) ## Available Options This product comes in different **Set** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ 10/10 would buy again *by J***A on May 4, 2026* I’ve been really impressed with the Waterdrop TSB 8 Layer Under Sink system so far.
