Description

[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. It is not suitable for well water or hot water. Suitable for faucets with 1/2" or 3/8" FEMALE NPT thread. Need to connect to a quick-connect faucet? Just reach out — we’ll gladly send free connection fittings.

Replacing your filter? To replace the filter for your WD-TSA-UF/TSB-UF under-sink water filtration system, Please search for B0CM8MHWNT for the WD-10PP filter, B0CM8KV1M9 for the WD-10GC filter, B0D1RBH4QX for the WD-10UF filter.

[0.01 μm Ultrafiltration and 9-stage Advanced Filtration] This under sink water filtration system includes 3 filters for 9-stage deep 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 0.01 μm ultrafiltration filter can reduce harmful substances that are as small as 0.01 μm and improves taste, ensuring 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. The PP filter can last for up to 6 months, the GC filter can work for 8-12 months while the UF filter can last 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.

[No Leaks, No Cracks] Made from quality materials, this filter system is twice as thick and built to last. It has successfully passed multiple rigorous durability tests, proving its ability to withstand high pressure and resist aging and freezing. This ensures that your filter system remains leak-free and crack-resistant, providing you with reliable, long-term performance.

[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 is not a professional way to measure the water quality. Essential Minerals, Calcium, Potassium, Sodium, Magnesium... These essential minerals are dissolved solids, PPM will not be dropping if you test with a TDS meter. Waterdrop undersink water filtration system is keeping all those minerals, but removes elements that are harmful to your body. Note: The activated carbon is made from natural coconut shells. Please confirm whether you are allergic to it.
