Waterdrop TSU-WB 0.01μm Ultra-Filtration Under-Sink Water Filter System

Clean, reliable water right at the tap

The Waterdrop TSU-WB 0.01μm Ultra-Filtration Under-Sink System sits neatly beneath your kitchen counter, delivering filtered water through a dedicated faucet. Its compact, tankless design frees up cabinet space while avoiding bulky tanks, making it a discreet upgrade for everyday use.

What the filtration technology can do for you

• A 0.01 μm ultrafiltration membrane reduces contaminants larger than 0.01 μm while preserving essential minerals in the water.
• Ingredients that influence taste and odor—chlorine, fluoride, and certain metals—are targeted for a clearer, fresher-tasting glass.
• There’s no wasted water, no need for a power source, and no noticeable drop in water pressure during daily use.

Note that the system preserves minerals such as potassium, calcium, sodium, and magnesium, contributing to a balanced mineral profile. It does not lower the TDS reading, which some meters measure as total dissolved solids. This is designed for municipal cold water and should not be used with hot water or well water.

Smart design, safety, and long-term savings

• Integrated waterways help prevent leaks, and you can replace the filter without shutting off the main water supply.
• Long-term filtration reduces maintenance: up to 24 months for the UF membrane, with PP and CT filters lasting 6 and 12 months respectively.
• Smart indicators on the panel keep you informed about water quality and when to replace filters for ongoing purity.

Installation made simple

Includes a stainless steel faucet, 3/8" inlet hose, 1/4" outlet hose, adapter, and everything you need for a quick setup. Install requires drilling a 1-inch hole in the countertop. It’s compatible with cold municipal water and is not intended for hot water or well water.

Practical tips for everyday use

• Expect mineral-rich water that’s pleasant for drinking, cooking, and beverage preparation, without altering your daily routines.
• Follow the smart panel indicators to keep the system performing at its best, and plan filter replacements accordingly.

Important note: This system does not reduce TDS and is designed for cold municipal water only.
