Overview
The Apec Water ROCT-C1 is a countertop reverse osmosis system with a 1.3 gallon capacity, built in polypropylene, aimed at anyone who wants RO level filtration without cutting into under sink plumbing.
Reverse osmosis is one of the more thorough filtration methods available for home use, and putting it in a countertop unit means no permanent installation or drilled faucet hole. The 1.3 gallon capacity points to a small household or occasional use rather than continuous high volume filtering.
- Reverse osmosis purification
- 1.3 gallon capacity
- Countertop install type
- Polypropylene construction
Who it's for
Fits renters or anyone who wants RO water quality without modifying under sink plumbing. Households needing large volumes of filtered water on demand should look at a higher capacity or under sink system instead.
Strengths and trade-offs
Drawn from this product's published specifications.
- Reverse osmosis filtration in a countertop form
- No drilling or permanent plumbing changes needed
- Compact 15.7 x 8.3 x 18.1 in footprint
- 1.3 gallon capacity limits volume between refills
- Rating is based on a small number of reviews
Performance notes
Reverse osmosis pushes water through a semi permeable membrane, which is generally more effective at reducing dissolved contaminants than carbon filtration alone. Being countertop rather than under sink, it trades some capacity and hands free convenience for the ability to set up and move it without a plumber.
