Kelda’s Air-Powered™ technology is the result of more than a decade of dedicated research, development, and laboratory testing. Developed in partnership with the University of Southampton, a world leader in engineering and innovation, our air-powered showers have been proven to reduce water consumption while enhancing the overall shower experience. In independent testing, 91% of women and 73% of men said that a Kelda shower feels as good as or better than a traditional shower – despite using significantly less water.
