Watts (WQCFU-T-11KIT) 11" Triple Stage Hollow Fiber UF, Carbon System
WQCFU-T-11KIT 11" Triple Stage Hollow Fiber UF System
Quick-change under-sink filtration with advanced hollow fiber ultrafiltration technology—no tank, no waste water, no reverse osmosis hassles
The Watts WQCFU-T-11KIT is a complete under-sink drinking water system that delivers 99% cyst removal, 95% lead reduction, and 97% chlorine removal without the complexity or water waste of reverse osmosis. This 11-inch triple-stage system uses quick-change cartridges with double O-ring seals and a hollow fiber ultrafiltration membrane to remove contaminants down to 0.1 micron while leaving beneficial minerals intact. Works efficiently at 20 psi minimum inlet pressure with zero reject water.
Three-Stage Treatment Process
5-micron sediment filter removes sand, silt, rust particles, and large particulate matter to protect downstream cartridges
5-micron activated carbon block reduces chlorine taste and odor (97%), VOCs (95%), herbicides, pesticides, and insecticides per NSF 42
0.1-0.3 micron ultrafiltration membrane removes cysts, bacteria, and reduces lead (95%) per NSF Standard 53
Why This System Outperforms RO
Quick-Change Cartridges
Single quarter-turn removal and installation with no filter sumps, no wrenches, no plumber required. Double O-rings prevent leaks
Zero Waste Water
100% of incoming water is filtered and used. Unlike RO systems that send 3-5 gallons to drain for every gallon filtered
No Storage Tank Needed
Operates on line pressure with only 3 psi drop at 0.5 GPM. Frees up valuable under-sink space and eliminates stagnant water concerns
Retains Minerals
Leaves beneficial calcium, magnesium, and trace minerals in your water while removing harmful contaminants down to 0.1 micron
Complete Installation Kit
Includes long-reach chrome faucet, tapping valve, color-coded tubing, mounting bracket, and all three pre-installed filter cartridges
Multi-Application Use
Suitable for residential kitchens, offices, restaurants, cafés, and commercial foodservice applications requiring reliable filtration
11-Inch Quick-Change Filters
| Cartridge Type | Model Number | Micron Rating | Stage Position |
|---|---|---|---|
| Sediment (Melt-Blown PP) | WQCSC11 | 5 micron | Stage 1 |
| Carbon Block | WQCCC11 | 5 micron | Stage 2 |
| Antibacterial Activated Carbon | WQCABC11 | 5 micron | Stage 2 (alternate) |
| Hollow Fiber Membrane (UF) | WQCHFC11 | 0.1 - 0.3 micron | Stage 3 |
System Family & Sizing Options
The WQCFU-T-11KIT is part of the Watts Quick-Change drinking water system family. Also available in 10-inch configurations (WQCFU-T-KIT with sediment, carbon, and UF), dual-stage 10-inch (WQCFU-D-KIT with sediment and carbon), single-stage 10-inch (WQCFU-AC-KIT with activated carbon), and 13-inch versions for higher-flow commercial applications. All replacement cartridges are available in three sizes: 10-inch, 11-inch, and 13-inch. Color-coded cartridges ensure you always install the correct filter in the correct stage position. Requires minimum 20 psi (1.4 bar) inlet pressure for proper operation.
Watts has been engineering water treatment solutions for residential and commercial applications for decades. The WQCFU-T-11KIT combines NSF-certified performance with maintenance simplicity that keeps your water clean without the ongoing service headaches of traditional filtration systems.
