## 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.

These added minerals not only make your water taste better but also support your physical health, improving bone strength and digestive health. Enjoy healthier, great-tasting water straight from your tap. 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. Its KDF materials reduce heavy metals and harmful substances, ion exchange resin reduces fluorides, and the alkaline filter enriches your tap water with beneficial minerals and improves taste, offering pure, healthy water.
- [Long Filter Lifespan] Enjoy pure water all year round. The 3 high-quality filters in this under sink water filter have impressive lifespans, lasting up to 12 months. This means fewer replacements and more convenience for you. Say goodbye to frequent filter changes and hello to long-lasting, clean water every day. Before going on vacation, please Put the filters in separate sealed plastic bags, and store the bags in your refrigerator (NOT the freezer) to keep it fresh in 30 days.

This significant boost enhances filtration capability, effectively trapping more impurities and reducing the risk of clogging.

- [Cannot filter well water or hot water]Only a cold-water source should be used to power the filter. 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!
