How It Works

On-Demand Pure Water at 800 Gallons Per Day

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.

What Changes After Installation

Pure, alkaline water on demand with no wait time and no wasted space.

No Storage Tank, No Wait

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.

Saves 70% of Under-Sink Space

Without a storage tank, the system takes up a fraction of the space of traditional RO installations, leaving room for other under-sink storage.

Alkaline, pH-Balanced Water

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.

Highly Efficient: 2:1 Drain Ratio

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.

Real-Time TDS Display

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.

Self-Maintaining Membrane

The auto-flush feature automatically cleans the RO membrane on a regular cycle, preventing mineral buildup and extending membrane life without any action required.
