Drinking Water Systems
Clean, great-tasting drinking water at your tap
City water is treated, not purified. The Kinetico K5 Drinking Water Station holds more NSF certifications than any reverse osmosis system on the market and removes over 99% of the contaminants left behind.
Why a drinking water system
A softener handles hardness. This handles what is left.
Columbus's municipal water meets EPA standards, and that is a meaningful baseline. But meeting standards means staying below legal limits, not being free of everything you would want to filter out. Disinfectants like chlorine, the byproducts they create, trace lead from aging plumbing, and emerging compounds can all remain in your glass. A whole-house softener solves hardness. A dedicated drinking water system solves the rest, and the two are designed to work together.
Reverse osmosis, done right
Two ways to get purified water at home
Kinetico K5 Drinking Water Station
The most certified RO system on the market
Kinetico's most advanced under-sink reverse osmosis system. It installs beneath your kitchen sink and delivers purified water through a dedicated faucet at the counter. No countertop clutter, no heavy pitchers, no refill delays.
- Removes over 99% of drinking water contaminants
- Holds more NSF certifications than any other RO system
- MACguard filters can only install in the correct position
- Continuous purified water, no waiting for a tank to refill
- Works with or without a Kinetico water softener
Kinetico Hydro Drinking Water System
Sleek, efficient, all-in-one filtration
A streamlined under-sink system that delivers Kinetico-quality reverse osmosis filtration in a compact, modern package. Significantly cleaner water than a pitcher filter or faucet attachment, with the build quality Kinetico is known for.
- Multi-stage reverse osmosis filtration
- Compact under-sink footprint
- Dedicated counter faucet for purified water
- Great choice when taste and general quality are the priority
- Performs well on softened and unsoftened water
Broad protection
The contaminants a K5 takes out of your water
The K5's multi-stage filtration covers the contaminants most likely to be present in Columbus-area water. Its five NSF certifications span taste and odor, health effects, system performance, emerging compounds, and PFOA and PFOS reduction, which is broader coverage than most reverse osmosis systems can claim.
Because the system filters at the point of use, the clean water you draw also fills the ice your freezer makes and the water your coffee maker uses. The result is water that simply tastes better, glass after glass.
Reduced by the K5
- Chlorine and chloramine disinfectants
- Disinfection byproducts
- Lead from aging plumbing
- PFOA and PFOS compounds
- Trace pharmaceuticals and hormones
- Arsenic and sediment

The most certified drinking water station you can buy
Certified to do what it claims
The K5 carries five NSF certifications: NSF 42 for chlorine taste and odor, NSF 53 for health effects including lead and cysts, NSF 58 for reverse osmosis performance, NSF 401 for emerging compounds like pharmaceuticals, and NSF P473 for PFOA and PFOS reduction. Most RO systems carry only one or two.

FAQ
Drinking water questions we hear all the time
The K5 installs under your kitchen sink, taking up about the same space as a compact under-sink cabinet. The filters, membrane housing, and a small storage tank fit neatly inside. A separate dedicated faucet is installed through the sink or countertop, typically next to your main faucet. We handle the complete installation, including the faucet, and most jobs take one to two hours.
It depends on your water and usage, but most households change filters once per year. The K5's MACguard system makes this straightforward because the filters can only be installed in the correct position. We can set up an annual filter service visit so you never have to think about it.
Older RO systems had a reputation for sending several gallons down the drain for every gallon purified. The K5 uses a more efficient design and is significantly better. For a household that replaces bottled water with the K5, the savings from not buying and disposing of plastic bottles far outweigh the system's water use.
Yes, and it is the combination we recommend most often for Columbus homes. A softener handles whole-house hardness, protecting your appliances, pipes, and fixtures. The K5 handles contaminants at the drinking tap. They solve different problems and are designed to work together, and the K5 performs well on both softened and unsoftened water.
The K5 is the most certified RO system available and the right choice if you want the broadest contaminant coverage, including PFOA and PFOS. The Hydro is a sleek, compact all-in-one system that delivers excellent everyday filtration when taste and general quality are the main priority.
