High-Efficient Double Electrolyzer
From Kenho

Smart water filtration ability and 10 electric plate generate electrolyzed water with rich hydrogen.

30 years since Kenho launched water ionizer series in 1989.HWP-77 upgraded with basic 5 plates PLUS new developed 5 more plates of hydrogen electrolyzer.

It generates better alkaline water which contains 1600ppb* of dissolved hydrogen.

*The dissolved hydrogen concentration may vary depending on the water quality. Different values may be measured depending on the tester.

ORP Value Is The
Best Ever Among
Our Past Ionizer Series

Oxidation reduction potential(ORP) describes water’s ability to release or accept electrons during a chemical reaction.

A high ORP indicates that there is a greater potential to oxidize than a low ORP.

Lower ORP describes a lower potential to cause or increase damaging oxidation.

Other Function

1. Easy To See LCD Screen
pH value, dissolved hydrogen, total water flow amount, usable remaining amount of filter are displayed to check on the screen.

2. Hydrogen Plus Button To Electrolyze Well Even If It Is Difficult Water Quality To Electrolyze
Concentration of hydrogen is about 4 times. When the synthetic water that water flow amount is 2.5 Liter per minute and pH is 9.5 was used.

Compared both normal and gydrogen plus mode. It may be different according to the water quality.

3. Kenho Water Can Generate Sanitized Water. (pH2.5) For Deodorant Throughout The House, Cleaning, Disinfection
The sanitized water which is generated by putting table salt is effective for cleaning and disinfection.

*Supplied cartridge for sanitized water and table salt are needed.

4. Filter Exchange Lamp
It will sound, light up and blink from the display when it is time to replace.

Easy-To-Use Function

Smart function that automatically keeps the pH constant
Equipped with the function that it automatically adjusts constant pH regardless of water flow amount *In case of Alkaline 1, 2, 3

Maximum flowing water quantity is about 5.5 liter per minute
Powerful use for washing vegetables and lifestyle.

Waste water is just a little
More alkaline water can be generated with less waste water. The ratio of Generated water and waste water is 19:1 which is industry’s leading class.

Water saving with non-waste water mode
Water could run without wasting water within 30 minutes after turning off the faucet.

Energy reduction with auto power off function
The machine automatically shut off the power after 30 minutes of use and turn to standby mode, then it prevents from over energy usage.

Less time and effort!
Regular maintenance of electrodes
Automatic cleaning systems

Easy-To-Put In The Kitchen!
Delivery pipe is enough 65 cm.

You Can Place The Machine According To Your Kitchen Style
