Overview
The Waterdrop WD-M6CG is a countertop reverse osmosis filtration system with a 4 liter capacity. It weighs 11.8 pounds and measures 16.44 by 9.25 by 14.74 inches, sized to sit on a counter rather than mount under a sink.
The 4 liter figure points to a built-in holding reservoir rather than a tankless, filter-on-demand design, which affects how much filtered water is available before a refill or wait is needed. Being countertop rather than under-sink, it needs no plumbing modification, trading that convenience for taking up visible counter space.

Who it's for
This suits renters or anyone who wants reverse osmosis filtering without cutting into under-sink plumbing. It is less suited to households wanting a system tucked out of sight, since it sits openly on the counter.
Pros and cons
- No plumbing changes needed for countertop setup
- 4 liter reservoir on hand
- Light enough to move at 11.8 lb
- Takes up visible counter space
- Reservoir limits water on hand to 4 liters
Performance notes
Reverse osmosis filtration removes dissolved contaminants by forcing water through a membrane, and the 4 liter reservoir here means filtered water accumulates for use rather than dispensing continuously. At 11.8 pounds it is light enough to move between counters or store away, unlike a plumbed system.
