Overview
Under-sink reverse osmosis filtration system from Ecoviva rated for 800 gallons per day, in a compact 6.5 x 18.8 x 17.1 in housing weighing 9.4 lb.
An 800 GPD rating puts this system well above entry-level RO units, which typically run in the 50 to 100 GPD range, suggesting it is built for households wanting faster refill rates rather than a slow trickle system. At 9.4 lb it is light for its output class, though the listing does not specify tank size or filter stage count, so buyers should verify those before assuming whole-house coverage.
- Reverse osmosis purification
- 800 gallons per day rating
- Under-sink install
- 9.4 lb
Who it's for
Fits households wanting under-sink reverse osmosis with a higher daily output than basic countertop units provide. Less suited to renters who cannot modify under-sink plumbing.
Strengths and trade-offs
Drawn from this product's published specifications.
- High 800 GPD throughput rating
- Compact under-sink footprint
- Light at 9.4 lb
- Filter stage count and tank size not listed
- Requires under-sink plumbing access
Performance notes
The 800 gallon-per-day rating describes maximum throughput under ideal conditions, not guaranteed real-world speed, which depends on incoming water pressure and filter condition. The compact 17.1 in width and 9.4 lb weight indicate a slim cabinet meant to fit inside a standard under-sink cavity alongside existing plumbing.
