From water vapor to
drinking water.
The KuSui, named after the Japanese words for
"air" and
"water," is a water cooler that directly liquefies
water vapor
in the atmosphere to create drinking water.
"If there is humidity in the atmosphere, safe drinking
water
can be created anywhere on the planet."
he possibilities are endless with this ground-breaking
method.

Developing the KuSui
Create safe drinking water, anywhere,
anytime.
This is MIZUHA’s basic principle.
The idea was to create a mechanism to produce drinking water from the moisture in the atmosphere.The challenge was to prevent bacteria from developing.Creating safe, bacteria-free drinking water was the objective for developing KuSui.
Development model
This model creates waterdrops through heat exchange and uses MIZUHA’s original ion exchange system to sterilize the water for drinking.Ion exchange enables the water to be self-sterilizing.Tests were repeatedly carried out to see long the sterility could be maintained.
Prototype for mass production
This model was aimed to generate more water through heat exchange and to further improve water quality.A product designer was appointed to design a machine that is easy to use and visually appealing.The design was reexamined in addition to function.The size, weight, and noise level, which had been designed according to the size of the heat exchanger, were factors that needed revision.
Mass production model
This is the remodeled version with functions reconstructed for mass production.The ion exchanger and the filter for the air inlet was redesigned, further enhancing water quality.
A smaller heat exchanger was implemented and the machine redesigned to reduce size.
A new function featuring a standard/quiet mode helps reduce the noise level.enabling installation in households. The carbon filter that must be replaced regularly was converted in to cartridgs,simplifyng the upkeep.
[Old specification] Nov. 2019 - Newly improved MIZUHA KuSui
KuSui has become even more user-friendly, with an improved faucet position and the new hassle-free filter replacement system. The heat exchanger—the very heart of the machine—has also been updated.
Carbon Filter
(Cartridge filter/Made in Japan)
>Carbon filter replacement system to enhance the taste of the water.
Air Purification Filter
(Cartridge filter/Made in Japan)
Air purification filter effective against PM2.5.
[Old specification] MIZUHA KuSui M-AWG-003 Ver. 2020
with Tandem Sanitization System
In 2020, the water circulation around the machine and within the tanks was revised for improved sanitization, providing users with water that is safer than ever.
The new "Tandem Sanitization System" was also introduced, where ion exchange units are placed inside both the upper and lower tanks, for enhanced sanitization.
Now the water is continua.
