Waterdrop TST-UF 0.01μm Under-Sink Filter | Stainless Steel, Removes 99% of Substances, No Drill

Waterdrop TST-UF 0.01μm Under-Sink Filter

Transform your kitchen water at the source with the Waterdrop TST-UF under-sink system. Designed for municipal cold water, it installs discreetly under the sink and doesn’t require any drilling. The result is water that tastes cleaner and feels crisper for everyday tasks like coffee, formula preparation, and family drinks.

What makes it stand out

Six filtration layers, including a precision ultrafiltration membrane, target substances larger than 0.01 microns. You may notice a more neutral flavor and reduced odors, while minerals like calcium and potassium stay in the water. The housing is lead-free 304 stainless steel, paired with a thick seal to help prevent leaks and extend service life.

• Important note: This unit does not reduce TDS and is intended for cold municipal water only.
• Fast and steady flow: up to 1.59 GPM, enough to fill an 8‑ounce cup in about 2.3 seconds.
• Long filter life: PP up to 6–8 months, UF up to a year, CT 12–24 months depending on use.
• Environmentally friendlier: fewer cartridge changes can mean less plastic waste over time.
• Replacement filters: compatible with WD-P1, WD-U2, and WD-C3 families; available separately for easy upkeep.

Easy installation and flexible placement

Hook it up to common 1/2" or 3/8" female NPT connections. It can sit on the floor, be mounted on a wall, or—even without a faucet hole—be attached to a compatible faucet without drilling. If you need quick-connect fittings, Waterdrop support can help with free options.

• DIY-friendly setup with available installation videos and guides.
• Premium materials and a sturdy seal deliver a durable, clean look in busy kitchens.

Real‑life uses and daily benefits

In everyday moments, you might notice crisper coffee, clearer drinking water for kids, and smoother mixes for powders. The system supports rapid preparation in busy mornings, water for cooking, and quick beverages, all while keeping water quality in focus without overpromising results.

Note: minerals such as calcium and potassium may remain in the water, and the unit intentionally does not reduce TDS. This approach aims to preserve a natural mineral balance while addressing taste and odor concerns.
