Who it fits
Good fit for
You should consider this system if you want mineral-rich water without the complexity of reverse osmosis. It suits homes with municipal tap water where you wish to remove chlorine, PFAS, and heavy metals. The zero wastewater design appeals to those concerned about water waste. It is ideal for compact kitchens needing a slim unit that fits under the sink without disrupting existing plumbing or requiring electrical outlets.
Who should skip it
Skip this option if you need to reduce total dissolved solids or soften hard water. The ultrafiltration membrane does not remove dissolved salts or minerals. It is also unsuitable for well water or hot water lines. If you require a faucet that does not need countertop drilling, this model requires a separate installation step. Additionally, if you prefer a system with no separate faucet, look for an integrated unit instead.
Verdict: The Waterdrop TSU offers efficient, mineral-retaining filtration for municipal water users who want to avoid wastewater. It is a practical, space-saving choice for standard under sink installations.
Key specs explained for Waterdrop TSU
Micron Rating: 0.01
This rating indicates the size of particles the membrane blocks. At 0.01 microns, the system captures bacteria, cysts, and fine sediment. You get cleaner water without removing healthy minerals. This is different from reverse osmosis, which uses smaller membranes and removes dissolved solids. Choose this if you want to retain natural mineral content in your drinking water.
Filtration Type: Ultrafiltration
Ultrafiltration uses pressure to push water through a semi-permeable membrane. It filters out contaminants larger than 0.01 microns. Unlike reverse osmosis, this process does not require electricity or a storage tank. It also produces zero wastewater. This makes it an efficient choice for renters or those seeking a low-maintenance system that works directly with your tap pressure.
Filtration Stages: 3
The system uses three sequential filters to clean your water. A polypropylene pre-filter catches large debris. A carbon block removes chlorine and odors. The final ultrafiltration membrane blocks microscopic contaminants. This layered approach ensures thorough filtration. You benefit from clean-tasting water that is safe for daily use. Compare this to single-stage filters that may not address all common water issues.
Certification: NSF/ANSI 372
This certification verifies that the materials in contact with water are lead-free. It ensures the system does not leach harmful substances into your drinking water. You can trust the hardware safety. This is a critical standard for any under-sink unit. When shopping, look for this mark to ensure your family is protected from lead exposure in the plumbing components.
Design and Build Quality
The unit is designed for under-sink installation, fitting into standard cabinet spaces. According to the listing, the physical dimensions are 6.38 inches wide, 18.6 inches high, and 18.4 inches long. The system weighs 14 pounds. These measurements allow it to sit beneath most kitchen sinks. The compact footprint helps it fit in tight areas, even if a garbage disposal occupies some room. You do not need to worry about large bulkiness taking up valuable storage space below your counter.
The faucet features a brushed nickel finish, which adds a durable and elegant touch to your kitchen setup. This finish complements most modern sink designs. The control panel is a sleek black unit with four indicator lights. These lights serve as a smart lifespan reminder. They show you when it is time to change the filters, making maintenance simple and worry-free. You do not need to guess when service is due.
The system includes a separate faucet that requires countertop drilling. It accommodates both 1/2-inch and 3/8-inch water pipes, ensuring compatibility with various plumbing setups. The design uses no power and produces no wastewater. This layout keeps the installation straightforward. You get steady water flow without complex electrical connections. The build focuses on practicality and space efficiency for everyday kitchen use.
Installation And Daily Operation
Setting up the Waterdrop TSU requires drilling a hole in your countertop for the separate faucet. The system connects to standard under-sink cold water lines. It accommodates both 1/2-inch and 3/8-inch pipes, so you likely need no special adapters. The listing states all installation components are included in the box. You must connect the unit to municipal tap water only. It is not suitable for hot water or well water sources.
Daily use is straightforward. The unit delivers water at a maximum flow rate of 1.05 gallons per minute. This provides a steady stream without compromising purification quality. The system produces no wastewater, which simplifies maintenance compared to reverse osmosis units. It requires no electrical power to operate, relying solely on water pressure.
Maintenance involves replacing three distinct filters on a schedule. The polypropylene pre-filter needs changing every six months. The carbon block filter requires replacement every twelve months. The ultrafiltration membrane lasts for twenty-four months. A sleek black panel with four indicator lights alerts you when a filter is due for replacement. This visual cue makes tracking maintenance simple. The brushed nickel faucet adds durability to the setup. You get clean water without the hassle of managing large bottled water containers on your counter.
Before You Buy This System
You will need a drill for the separate faucet, as this unit does not include a deck-mounted option. Ensure your cabinet has enough depth for the 18.4-inch length, especially if you have a large garbage disposal. The system connects to cold water only; it is not suitable for hot water lines or well water sources. You must monitor filter changes carefully. The polypropylene pre-filter lasts six months, the carbon block twelve months, and the ultrafiltration membrane twenty-four months. This maintenance schedule is distinct from reverse osmosis systems, which often require more frequent membrane replacements. Since this unit retains minerals and produces no wastewater, it suits those who want simple upkeep without power. It fits well in compact kitchens where space is tight. Check your water pressure stability, as the system maintains flow without a pump. If you prefer mineral-rich water, this under-sink setup is a practical choice.
Check before you buy
- Confirm you can drill a countertop hole for the separate faucet.
- Verify your cabinet depth fits the 18.4-inch unit length.
- Ensure your water source is municipal tap water, not well water.
- Check that your lines are cold water only, no hot water.
- Plan for replacing the PP filter every six months.

Frequently asked questions
Does the Waterdrop TSU remove dissolved minerals from water?
No, it does not. The 0.01 micron ultrafiltration membrane allows healthy minerals to pass through while blocking larger contaminants. This differs from reverse osmosis systems that strip TDS. You retain beneficial nutrients like calcium and magnesium in your drinking water.
Is this system suitable for well water with high sediment?
It handles fine sediment well due to the 0.01 micron rating. The polypropylene pre-filter catches larger particles first. However, it does not remove dissolved solids or chemicals. If your well water has high chemical contamination, this unit alone may not be sufficient.
How much space does the WD-TSU unit require under the sink?
The unit measures 6.38 inches wide, 18.6 inches high, and 18.4 inches long. It weighs 14 pounds. You need a cabinet with enough depth to accommodate the 18.4-inch length. Ensure you have clearance for the connections and the separate faucet installation.
Does the Waterdrop TSU produce wastewater during filtration?
No, it does not produce wastewater. Ultrafiltration uses pressure to push water through the membrane without a waste stream. This makes it more water-efficient than reverse osmosis systems. You get filtered water without discarding a portion of your supply to the drain.
What types of contaminants does the 0.01 micron membrane block?
The membrane captures bacteria, cysts, and fine sediment. The 0.01 micron size is small enough to trap most microorganisms. The carbon block stage also reduces chlorine and some chemicals. You get cleaner water without removing essential dissolved minerals.
Can I install this filter on both hot and cold water lines?
No, the system connects to cold water only. Ultrafiltration membranes are designed for cold water pressure and temperature. Using hot water could damage the membrane or reduce filtration efficiency. You must connect the unit to the cold water supply line under your sink.
