A tidy under-sink carbon filter for city water that cuts chlorine taste and listed contaminants at a separate faucet. It does not lower dissolved minerals and is not for well water.

Overview
Kitchen sinks on city water are where this Waterdrop filter fits, mounting under the counter and feeding its own stainless faucet. A carbon block made from coconut shells reduces chlorine, lead and PFAS while leaving minerals in.
Tool-free filter swaps and push-fit tubing make ownership simple, and the certifications back the chlorine and lead claims. It is a carbon filter, not reverse osmosis, so total dissolved solids readings will not drop.
Who it's for
Renters and homeowners on municipal supply who want better tasting water for drinking and cooking without bottles. Well water users and anyone wanting mineral removal need a different system.
Pros and cons
- Filter swaps without tools
- Retains beneficial minerals
- Certified for chlorine taste and odor
- Lead reduction tested
- Cold municipal water only
- Does not reduce TDS
- Coconut shell carbon may affect allergies
Performance notes
Contaminant reduction depends on contact time in the carbon block, so flow and filter age matter, and the larger dirt-holding area slows clogging from sediment. Because carbon does not remove dissolved minerals, a TDS meter shows little change even when chlorine and lead are reduced.

Frequently asked questions
Is the Waterdrop WD-10UB a reverse osmosis system?
No. It uses activated carbon block filtration and retains minerals such as calcium and magnesium, so TDS readings will not drop.
Can I use the Waterdrop WD-10UB on well water?
No. It is designed for municipal tap water and cold water sources only.
Can the Waterdrop WD-10UB connect to my existing faucet?
It comes with its own dedicated faucet. Waterdrop points owners who want to use an existing drinking faucet to its WD-15UC-UF system instead.
How do I change the Waterdrop WD-10UB filter?
A twist-and-lock design lets you replace the filter in 3 seconds without tools. The replacement filter is the WD-RF10.
