Drinking water
Better water at the tap you actually drink from.
A softener treats the whole house. The K5 Drinking Water Station finishes the job at the kitchen sink, where the water becomes coffee, dinner and the glass on your nightstand.

What the test tends to find here
Columbus city water arrives disinfected with chlorine, which protects it in the pipes and flavors it at the tap. City and well water alike carry the dissolved minerals this part of Ohio is known for, and well water adds its own variables, iron and sulfur most often.
None of it is exotic, and all of it shows up in a twenty minute test. The K5's filter set is then built from those results, which is the difference between filtering your water and filtering water in general.

How it works
Four stages between the pipe and your glass
Prefiltering
Sediment and carbon catch particles and take out the chlorine taste city water often carries. That protects the membrane and improves everything downstream.
The membrane
Household pressure pushes water through openings so fine that most of what is dissolved in the water cannot follow. What stays behind is rinsed to the drain instead of collecting inside the system.
Storage
Treated water gathers in a tank under the sink so there is always some ready. Filling a stock pot feels no different from using any other tap.
The final polish
One last carbon pass happens on the way to the faucet, a finishing step just before your glass.
Certified
Tested against public standards, not our own
Anyone can print promises on a box. The K5 platform carries certifications against NSF/ANSI standards, which means independent testing against a published standard, on record where you can look it up.
- NSF/ANSI 42, taste, odor and chlorine reduction
- NSF/ANSI 53, contaminants with health effects
- NSF/ANSI 58, the reverse osmosis system standard
- NSF/ANSI 401, emerging compounds such as trace pharmaceuticals
- NSF P473, reduction of PFOA and PFOS

Living with it
Its own faucet, and no chores
Treated water arrives at a dedicated faucet beside your main tap, and it can be plumbed to the refrigerator and ice maker as well. We handle the filter schedule and the changes, so the system that was sized to your home stays looked after by the people who installed it.
Cost
Priced in writing, at the test
The exact configuration and price come out of your water test, and both arrive in writing. Set the cost against a year of buying, hauling and storing bottled water, and the math tends to finish the conversation on its own.
The alternatives
Why homes move past pitchers and bottles
- A pitcher filters slowly, holds little, and lives in the refrigerator
- Cartridge filters treat taste but far less of what is dissolved
- Bottled water is bought, hauled, stored and thrown away, forever
- The K5 treats water as you use it, at the sink, from your own supply

The pairing
Softener for the house, K5 for the glass
The two systems do different jobs and do them better together. The softener protects the plumbing, the appliances and the shower. The K5 finishes the kitchen tap for drinking and cooking. Most homes that start with one add the other, in either order. See the softeners.
