Company Overview

We are pioneering the market introduction of powerful, autonomous, safe and eco-friendly water and air treatment solutions, based on our technological breakthroughs in on-site generation of hydrogen peroxide. HPNow’s technology enables on-demand, highly-efficient production of hydrogen peroxide using only water, electricity and air.

With our compact and autonomous on-site HPGenTM hydrogen-peroxide generators, we are set to displace presently used and increasingly regulated chlorine and hazardous high concentrate chemicals across multiple water and air treatment sectors. In doing so we will provide our users with cost savings, reduced logistical burdens, and increased yields, while enhancing water, air and food safety and reducing the environmental impact of today’s toxic disinfectant agents.

Our Team

HPNow’s management team consists of a strong and balanced mix of technical and business expertise. A common thread is a high level of motivation for bringing the premise of the HPNow technology to the market.
