Waterdrop TST-UF 0.01μm Under-Sink Water Filter — Stainless Steel, 99% Substances Removal, Long Filter Life

Experience fresh, balanced water at home

The Waterdrop TST-UF 0.01μm Ultra-Filtration Under-Sink System brings cleaner taste and dependable performance straight from your kitchen sink. Crafted with a sturdy stainless steel body, it blends into modern kitchens while delivering filtration that targets impurities without altering your tap water’s natural mineral balance.

Important compatibility and usage notes: this system is designed for municipal cold water and does not reduce TDS. It can connect to cold water sources only and works with 1/2" or 3/8" female NPT threads. If you need quick-connect adapters, our team can provide free connection fittings. It isn’t suitable for well water or hot water.

Why this under-sink filtrations system stands out

• Efficient, high-capacity filtration with a 6-layer filter stack and a precision ultrafiltration membrane that targets impurities larger than 0.01 microns.
• Better taste and beverage versatility– ideal for everyday drinking water, coffee at home, and even preparing milk powder or skim drinks for little ones.
• Fast, reliable flow up to 1.59 GPM, delivering a cup of water in about 2.3 seconds for quick meal prep and faster coffee or tea.
• Long filter life—PP filter lasts 6–8 months, UF filter about a year, and CT filter 12–24 months, reducing maintenance and plastic waste over time.
• Eco-conscious design helps cut plastic waste with fewer cartridge changes, contributing to a lighter environmental footprint.
• Durable, lead-free materials featuring 304 stainless steel and robust seals to minimize leaks and extend product life.

Installation and maintenance made simple

Install is straightforward for both DIY enthusiasts and beginners. The system connects directly to your 3/8" or 1/2" pipe, with optional faucet mounting if you want a compact setup on the sink. If you ever need help, installation videos and a responsive support team are just a message away.

• Replacement filters: search for B0D91M9322 (WD-P1), B0D91VJ8ZK (WD-U2), or B0D91VQ298 (WD-C3) when it’s time to refresh your filtration.
• Flex placement: mount on the floor, hang on the wall, or attach to a faucet for space-saving layouts.

Notes on minerals and maintenance

The system preserves natural minerals such as potassium, calcium, sodium, and magnesium, aligning with a balanced water profile. It uses coconut shell-derived materials in parts of the filtration process. If you have a coconut allergy, consider this before use.

Summary: Waterdrop’s TST-UF under-sink system offers a practical upgrade to household water quality with a focus on taste, reliability, and eco-friendly upkeep. While it does not alter TDS, it provides thorough filtration and flexible installation options to suit a variety of kitchen layouts.
