Why a dedicated drinking water system?
A whole-home system protects your plumbing, skin, and appliances — but reverse osmosis is the step that addresses dissolved contaminants at the glass. In the Triangle, where utility water tests above health guidelines for several contaminants including PFAS, an under-sink RO is the highest-impact upgrade per dollar for the water your family consumes. Most of our customers pair one with a whole-home system; it also works great on its own.
Tankless High-Output Reverse Osmosis
A modern tankless RO that purifies on demand — no storage tank taking up the cabinet, no waiting for it to refill. Up to 800 gallons per day of output keeps up with big families, entertaining, and filling stock pots without slowing down.
Highlights
- 800 GPD tankless design — frees up cabinet space
- Quick-connect fittings for clean installation
- Easy filter maintenance and monitoring
- Faucet finish matched to your kitchen
- 1-year limited warranty
What you get
- Purified water on demand, no refill lag
- Removes dissolved contaminants at the tap
- Better-tasting coffee, tea, and ice
- Less bottled water to buy and haul
Note: not intended for microbiologically unsafe water without proper disinfection — on well water we pair RO with UV disinfection when testing calls for it.
5-Stage Reverse Osmosis
The time-tested workhorse of drinking water filtration. Five stages progressively remove sediment, chlorine, and dissolved impurities, and a storage tank keeps purified water ready at a dedicated faucet — simple, reliable, and easy to service.
