7-stage tankless reverse osmosis with 800 GPD capacity and on-demand alkaline water. No storage tank, no wait time, and 70% less under-sink space than traditional RO systems.

The AlkaPro 800 eliminates the main limitation of traditional under-sink RO: the storage tank. Instead of slowly filling a 1-3 gallon reservoir, this system produces purified water on demand at 800 gallons per day. The water is there the instant you turn the faucet on.
Seven filtration stages including sediment pre-filtration, double carbon block, a spiral-wound RO membrane, GAC polishing, an alkaline remineralizer, and a final GAC polish. The result is ultra-pure water with a balanced pH and beneficial minerals added back in. A real-time TDS display confirms the system is working at all times.
Your system includes a dedicated drinking water faucet. Choose your finish to match your kitchen.





Pure, alkaline water on demand with no wait time and no wasted space.
Traditional RO systems store 1-3 gallons of purified water and refill slowly. At 800 GPD, the AlkaPro 800 delivers pure water on demand the moment you open the faucet.
Without a storage tank, the system takes up a fraction of the space of traditional RO installations, leaving room for other under-sink storage.
The built-in alkaline remineralizer adds calcium, magnesium, and potassium back into the purified water and raises pH to a balanced 7.5-9.0, mimicking natural spring water.
Traditional RO systems waste 3-5 gallons for every gallon purified. The AlkaPro 800 uses only 2 gallons to produce 1 gallon of pure water, saving thousands of gallons per year.
A built-in display shows the current TDS reading so you always know exactly how pure your water is and can confirm the system is performing correctly.
The auto-flush feature automatically cleans the RO membrane on a regular cycle, preventing mineral buildup and extending membrane life without any action required.
