BRITA Group is a strategic minority investor in Hello Klean. Hello Klean remains independently operated and led by its co-founders, Karlee Zhang and Omer Ozener. 

Announced 12 March 2026 · London

BRITA's first-ever beauty investment

Hello Klean pioneered shower filtration as a beauty category. In March 2026, we secured investment from BRITA Group in the company’s first ever move into beauty and personal care.

BRITA has taken a minority stake in Hello Klean. Terms are undisclosed.

The partnership brings Hello Klean's expertise in hard water beauty together with BRITA’s 60 years of filtration innovation. It allows us to remain independently led, continuing our category-defining approach to water-optimised beauty, all while gaining access to world-leading filtration research, testing and manufacturing.

Why BRITA, why now

Hard water affects more than 60% of homes in the UK, over 85% in the US, and a similar share across Europe and the Middle East. It remains one of the most misunderstood and overlooked factors in hair and skin health. But we’re changing that. 

Hello Klean built a subscription-led, digitally native brand around solving this problem. BRITA brings the filtration science to match it. Together, we’re accelerating our ambition to become the definitive shower filtration brand across the world. Building new products and pushing international expansion. 

What was said

“Hello Klean has rapidly proven the rising global demand for smarter water-quality solutions in daily life. For BRITA, this partnership is a strategic move into a category where our decades of filtration expertise can create meaningful value.”
— Markus Hankammer, CEO, BRITA Group
“We built this category before anyone was paying attention. When we started, ‘shower filtration' wasn't a beauty conversation, it was a plumbing one. We started with £60k and our own bathroom, won Dragons' Den, and proved the model works. BRITA saw what we saw early: that water is the first ingredient in every routine, and most people are fighting against it.”
— Karlee Zhang, Co-Founder and CMO, Hello Klean
“We grew to double-digit-million revenue without a single pound of external equity funding. We took BRITA's investment because it brings something money can't buy: six decades of filtration IP, global manufacturing, and scientific credibility. With BRITA, we have the infrastructure to make water quality a standard part of every beauty routine.”
— Omer Ozener, Co-Founder and CEO, Hello Klean

What this partnership means — and what it doesn't

  • A strategic minority investment. BRITA Group holds a minority stake in Hello Klean. Hello Klean is not owned by BRITA and is not a BRITA subsidiary.
  • Independently operated. Hello Klean remains founder-led. Hanns-Michael Arenz, Director M&A and Corporate Venture at BRITA Group, joined the Hello Klean board as a non-executive director.
  • R&D collaboration. Hello Klean now has access to BRITA's R&D infrastructure, ISO-certified testing facilities, manufacturing network and six decades of filtration expertise.
  • Our products remain our own. Hello Klean develops and tests its own products. Our shower filtration is independently tested by SGS. BRITA's investment doesn’t mean Hello Klean products use BRITA technology, and it isn’t a product certification.
