Overview
The Electrolux EWD800A0W is an under-sink reverse osmosis filtration system rated for 800 gallons of capacity. It measures 17.7 by 6.7 by 17.2 inches, sized to fit inside a standard sink cabinet.
Reverse osmosis under-sink systems like this one filter water at the point of use rather than treating the whole house, and the 800 gallon figure typically refers to filter or membrane life before replacement is needed. Amazon shows a full 5 star average for this listing, though that is based on only 7 ratings, a small sample to draw broad conclusions from.
- Reverse osmosis purification
- 800 gallon capacity
- Under-sink install type
- 17.7 x 6.7 x 17.2 in
Who it's for
This suits households wanting dedicated, filtered drinking water at the kitchen sink without replumbing the whole house. It is not intended as a whole-house filtration or softening solution, since it is sized and installed for a single point of use.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reverse osmosis filtration at the point of use
- Compact enough for under-sink install
- 800 gallon rated capacity
- Rating based on only 7 reviews
- Single-point use, not whole house
- No stated filter replacement schedule
Performance notes
Reverse osmosis pushes water through a semi-permeable membrane to remove dissolved contaminants, a slower and more thorough process than a basic carbon filter. The 800 gallon rating marks how much filtered water the system is built to produce before its filters need replacing, though actual life varies with source water quality.
