About our Company

Ohen Group's ozone generators have been sold since 2009, but Ohen Group's services, online platforms, support structure and company our customers have come to know and love were only launched when our founders acquired the intellectual property of these ozone generators in 2021.

Our founders merged their existing Holistically Yours Therapy and Holistically Yours Shop (est. 2018) with the ozone generator intellectual property all under one roof as Ohen Group (Pty) Ltd.

Our decision to acquire the ozone generator intellectual property from the engineers was one of opportunity; we saw a powerful ozone generator in the industry where we could improve its reach in helping many more customers, provide more efficient customer support, easier access to after-sales service and online resources. We eliminated high lead times, distributors and the need for pre-orders - we knew it was our duty to improve this customer experience standard to match the high-quality ozone generator, and so Ohen Group was re-branded and re-launched under new ownership. 

We pride ourselves on our high-quality standards, lightning fast turn-around and response times, extensive knowledge and resources we share with our customers freely and the all-round customer service and quality products we provide.
