Overview
A reverse osmosis membrane is the core of this under-sink Apec system, supported by carbon and mineral stages. It runs on water pressure alone and ships with a tank, faucet, tubing and wrenches.
The reason to look at it is the certified performance and the high TDS ceiling without any electrical hookup. The limit is the installation, which involves a drain saddle and a faucet hole.
Who it's for
Homeowners comfortable with basic plumbing who want certified reduction at a dedicated faucet. Renters and anyone avoiding plumbing work should choose a countertop or pitcher filter.
Pros and cons
- High TDS ceiling
- Runs on water pressure
- Install kit included
- Plumbing work required
- Slow flow rate
- Needs under-sink space
Performance notes
Reverse osmosis pushes water through a semipermeable membrane at line pressure, so household pressure sets the output. The daily rate is a membrane figure, not a flow at the tap. A storage tank holds treated water so the faucet can run faster than the membrane produces.
