Overview
The Apec Water ROES-100 is an under-sink reverse osmosis filtration system rated for 100 gallons per day. Built with polypropylene housings and sized 16 x 5.25 x 17.5 inches, it recorded 100 recent buyers in this data set.
Reverse osmosis systems work by forcing water through a semipermeable membrane, which is why they generally address a broader range of dissolved contaminants than carbon-only pitchers or dispensers. The tradeoff is slower production and some drain water use, standard for RO rather than a downside specific to this unit.

Pros and cons

- RO systems produce drain water as part of the process
- Under-sink install requires plumbing space and setup
Performance notes
Reverse osmosis pushes water through a membrane rather than relying on carbon adsorption alone, which is why RO systems generally address a wider range of dissolved solids than pitcher filters, at the cost of production speed rated here at 100 gallons per day.
