Overview
The Waterdrop WD-CT01 is a countertop filtration system using activated carbon media, rated for 300 gallons, with NSF/ANSI approved components in its build.
As a countertop unit, this system sits out on the counter and connects without permanent plumbing changes, trading the lower profile of an under sink install for easier setup. The 300 gallon rating is modest next to larger whole system filters, suggesting a household or small volume use case.

- No installation, sits on the counter
- Compact 14.43 x 10.61 x 13.43 in footprint

Performance notes
Activated carbon filtration is effective at reducing chlorine taste and odor, and NSF/ANSI approved components add a documented standard behind the build materials. The 300 gallon capacity means replacement will come sooner than with larger reverse osmosis or under sink systems rated in the thousands of gallons.
