PuROTwist Reverse Osmosis System

The PuROTwist Reverse Osmosis System gives you pure drinking water with its tough four-stage purification process. With dependable Omnipure® filters and John Guest® quick-connect fittings, plus handy parts like an auto shut-off valve and tank ball valve, this system is built to last and easy to use. Mount it under your sink, and you’ll have an endless supply of clean, refreshing water for drinking, cooking, and daily chores.

You can pick either a non-air gap or air gap faucet, and the system will still give you the same great water. The full-flow 3/8" tubing lets water travel quickly straight from the tank to the faucet.

Four-Stage Filtration Process

Stage 1—Sediment Filter 

Catches dirt, rust, and any small particles that could jam the filters that follow.

Stage 2—Carbon Block Filter 

Cuts down on chlorine, chloramines, and other chemicals that mess with taste and can harm the RO membranes.

Stage 3—TFC Reverse Osmosis Membrane 

Traps dissolved salts, heavy metals, and other contaminants, leaving you with clean, low-TDS water.

Stage 4—Post Carbon Filter 

Gives the final polish, ensuring that the water tastes as fresh as it looks before it reaches your glass.

Model Options

• PT4000T50-SS NA 4-stage, 50 GPD TFC RO system with a straight, non-air gap faucet.
• PT4000T50-SS AG 4-stage, 50 GPD TFC RO system with a classic air gap faucet.

Both models filter the same way. Pick the faucet style that lines up with your plumbing and your taste.
