About this item

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.
  • [Easy to Install] Installation is a breeze! With twist-and-lock design, you can set it up in 3 minutes and replace filters in just 3 seconds all by yourself without a plumber.
  • [No Clogging Issues] This under sink water filter features an upgraded filtration area that offers a 20X increase in dirt adhesion. This significant boost enhances filtration capability, effectively trapping more impurities and reducing the risk of clogging. Enjoy consistently cleaner water with less maintenance hassle, ensuring a smooth and worry-free experience for you and your family.
  • [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.

Highly recommend! We confidently use water directly from our faucet and it tastes great. Not too difficult to install and easy to switch out each filter when necessary.

The install was a little bit hard the quality of the Teflon tape could be better had to go to store to get some. Swapped the mounting screws for magnetic ones. But other than that wonderful product!! So very excited.

Great under sink filter for city water with chlorine fluoride and bad taste. Easy install comes with everything you need. Water taste is greatly improved with the alkaline filter. Real nice tall spicket with smooth valve action. Bottom line, good unit.
