What a Reverse Osmosis System Does

A reverse osmosis system is installed under your kitchen sink with its own drinking water faucet. Water is pushed through a 0.0001 micron membrane that reduces up to 99% of over 1,000 contaminants, including PFAS, lead, arsenic, fluoride and total dissolved solids.

Common reasons homeowners add reverse osmosis:

  • Buying bottled water or refilling jugs
  • Water that tastes like chlorine or minerals
  • Concerns about PFAS, fluoride or microplastics in drinking water
  • Better tasting coffee, tea and ice

How Our Reverse Osmosis System Works

Water passes through four filter stages and a UV light before it reaches your faucet. Each stage targets a different problem.

Seven layer reverse osmosis filtration with alkaline remineralization and UV
Stage 1

Sediment Filter

Removes sediment and particles such as dirt, rust and sand.

Stage 2

Anti Scale Carbon

Activated carbon with anti scale media that reduces chlorine and helps prevent scale.

Stage 3

Reverse Osmosis Membrane

A 0.0001 micron membrane that reduces PFAS, lead, arsenic, fluoride and total dissolved solids.

Stage 4

Alkaline Remineralization

Adds minerals back to the water to balance pH and improve taste.

Final Stage

Built In UV Light

A UV light treats the water as a final stage before it reaches your faucet.

Tankless

No storage tank, so it takes up less space under the sink.

Fast Flow

Up to 500 gallons per day with a built in boost pump.

Filter Life Monitor

Automatic reminders when a filter is due for replacement.

Leak Stop Valve

Automatically shuts the system off if a leak occurs.

Built by iSpring, a maker of NSF/ANSI 58 certified reverse osmosis systems.

What Reverse Osmosis Does Not Do

Some water problems need a different system. Your water test shows whether you need any of these.

Filter Every Tap and Shower

Reverse osmosis treats one faucet. For filtered water throughout the home, add a whole home water filter.

Soften Hard Water for the Entire Home

Reverse osmosis at the sink does not soften the rest of your home. For that, add a water softener.

Kill Bacteria for the Entire Home

The built in UV light treats drinking water at the kitchen sink only. For the whole home, add a UV light to your main line.

"Honestly one of the best experiences I've had with any company. They tested my water, broke it all down in a way that actually made sense, and were genuinely kind the whole time. The install was fast and clean, and I could taste and feel the difference right away. If you're thinking about getting your water checked, these are the people to call."

"I came in knowing almost nothing about water systems, and they made it simple from the start. Everything got explained clearly, what the system does, why it matters, with no pressure at all."

Frequently Asked Questions

What does reverse osmosis remove?

The RO membrane reduces up to 99% of over 1,000 contaminants, including PFAS, lead, arsenic, fluoride and total dissolved solids. The carbon stage reduces chlorine, and the alkaline stage adds minerals back for taste.

Is reverse osmosis better than a whole home filter?

They do different jobs. Reverse osmosis treats drinking and cooking water at one faucet. A whole home filter treats every tap and shower in the home. Many homes use both. See whole home water filtration.

Where is the system installed?

Under the kitchen sink, with a dedicated drinking water faucet on the counter or sink.

Can it connect to my refrigerator or ice maker?

In many homes, yes. Ask about it during your free water test.

Does reverse osmosis waste water?

Our system has a 2 to 1 pure to drain ratio. For every 3 gallons it processes, about 2 go to your faucet and 1 goes to the drain to rinse away what the membrane removes.

How often are the filters changed?

The sediment, carbon and alkaline filters last up to 12 months, and the membrane up to 24 months. A filter life monitor reminds you when one is due, and we check the system at your annual quality check.

Do I need reverse osmosis if I have a water softener?

A softener removes hardness but does not reduce contaminants like PFAS, lead or fluoride. Reverse osmosis at the kitchen sink handles drinking water.

How much does a reverse osmosis system cost?

Pricing and bundles are listed on our Products page. Financing options are available.

Is the warranty really lifetime?

Yes. Every system includes a 100% fully backed lifetime warranty, as long as annual maintenance is kept up.
