Drinking Water · Reverse Osmosis

Reverse osmosis drinking water, from your own tap.

Healthy habits start with the water you drink. An under-sink reverse osmosis system gives you bottled-water quality at the kitchen faucet: five stages, NSF/ANSI 58 certified, 98% rejection of dissolved solids, and proven against PFAS. Maintenance is one filter change a year.

Clean drinking water from an under-sink reverse osmosis faucet

In short

What it is
The dissolved contaminants a softener or iron filter was never built to catch: PFAS ("forever chemicals"), lead from old plumbing, nitrate, arsenic, and the sodium a softener adds. All invisible, all tasteless.
What it does to the house
Nothing to the pipes or fixtures. This is about the water you drink and cook with, and a private well isn't tested for any of it unless the owner arranges it.
What fixes it
Reverse osmosis under the kitchen sink: a membrane so fine that dissolved chemicals can't follow the water through it. NSF/ANSI 58 certified, including for PFOA and PFOS. One filter change a year.

Is this your water?

A softener and an iron filter fix the water you wash with. Neither is designed to remove the small dissolved contaminants that matter most in the water you drink and cook with: lead from old plumbing, nitrate, and PFAS. Reverse osmosis pushes water through a membrane with passages around a ten-thousandth of a micron, and sends what it rejects down the drain.

warranty
  • Molecular-level filtration. A polyamide membrane with ~0.0001 micron passages rejects 95–99% of dissolved solids: lead, arsenic, nitrate, sodium, fluoride.
  • Proven against PFAS. EPA lists reverse osmosis as Best Available Technology for PFOA and PFOS, with removal greater than 99%.
  • Multi-stage protection. Sediment and carbon block prefilters protect the membrane; a final carbon polish delivers clean taste at the tap.
  • Always ready. A pressurized storage tank keeps treated water on hand for drinking, cooking, coffee and ice.
  • Five-stage system, NSF/ANSI 58 certified for PFOA and PFOS reduction. 50 GPD membrane, 4-gallon storage tank, color-matched faucet.

Replaces bottled water

Pennies per gallon, no hauling, no plastic. One faucet that everyone in the house actually uses.

Finishes what the softener starts

Softening removes hardness, not dissolved contaminants. RO handles the water you drink, including the sodium a softener adds.

Emerging contaminants

PFAS regulations apply only to public utilities and are still years from enforcement. Point-of-use RO puts that protection at your sink now.

Simple upkeep

Prefilters once a year, membrane every few years. We track the schedule and service it for you.

How it works

  • 1. Prefiltration. A sediment filter removes particles; a carbon block strips chlorine, which would otherwise destroy the membrane.
  • 2. Membrane. Pressure forces water through the RO membrane. Water passes; dissolved contaminants are rejected and sent to drain.
  • 3. Storage and polish. Treated water fills a pressurized tank, then passes a final carbon filter on its way to a dedicated faucet.

What happens after you call

  1. 1Brian calls you back.Usually within one business day and we pick a day and time that works for you.
  2. 2We test your water at your house.Hardness, iron, pH, TDS and anything else your symptoms point to.
  3. 3You get a plain-English explanation and a real price.No pressure, no "manager approval" games.

After the install

  • Salt delivery, loaded into the brine tank on a schedule that fits your household.
  • Check-ups and filter changes, tracked and scheduled for you.
  • Service and repair by the person who installed it. Clack WS1 valves are the most widely serviced residential platform in the industry.

Installed in Portage, Kalamazoo, Vicksburg, Schoolcraft, Mattawan, Paw Paw and across Southwest Michigan.

Questions we get at the kitchen table

Does reverse osmosis remove PFAS?

Yes. The EPA lists reverse osmosis as Best Available Technology for PFOA and PFOS, with removal greater than 99%. Our systems are certified to NSF/ANSI 58.

How often do the filters need changing?

Once a year. It’s a five-minute swap, and we track the schedule and can do it for you along with your other equipment.

Can it feed my refrigerator or ice maker?

Yes. An ice maker / fridge line is one of the options, along with remineralization and a UV stage.

Doesn’t RO strip the minerals out?

It removes most dissolved minerals along with the contaminants, which is what makes the water taste clean. If you prefer a little mineral taste, a remineralization stage adds it back after the membrane.

Does it remove nitrate?

Yes. Reverse osmosis is one of the two EPA-listed technologies for nitrate, and NSF/ANSI 58 carries a specific nitrate/nitrite reduction claim. It covers the tap it’s installed on; for every tap in the house, see the whole-home nitrate filter.

What’s the warranty?

2 years, with a color-matched faucet so it looks like it belongs at your sink.
