Overview
The Waterdrop WD-TSU is an under-sink filtration system rated for 2200 gallons of activated carbon filtration, built with NSF/ANSI approved components. At about 14.8 x 4.7 x 14 inches, it fits inside a standard under-sink cabinet.
This is a plumbed system rather than a pitcher or faucet attachment, so it requires connecting to the cold water line under the sink. The 2200 gallon capacity gives a sense of the filter's working life before replacement, though actual duration depends on household water usage and incoming water quality.

Who it's for
Suited to a household ready to do, or hire out, an under-sink install for filtered water at the kitchen tap. Not the choice for anyone wanting a no-install pitcher or faucet-mount option.
Pros and cons
- 2200 gallon rated capacity
- NSF/ANSI approved components
- Compact under-sink footprint
- Requires under-sink installation
- Activated carbon alone does not address every contaminant class
Performance notes
Activated carbon filtration targets chlorine taste and odor along with some organic contaminants; the NSF/ANSI approved components indicate the parts meet recognized material and structural standards. The 2200 gallon capacity is the manufacturer's rated filter life before a cartridge change is needed.
