About Us

You can't tell what's in water just by looking at it.

Clear water can be clean or the opposite. It is precisely this doubt that prevents people from drinking from streams, wells, or unfamiliar taps, and it is precisely this doubt that we wanted to eliminate. Not with a promise, but with something that can be verified.

Proof before promises. Our filters work without electricity, without chemicals, without batteries. We had the filter performance tested by an independent laboratory according to a recognized testing protocol for drinking water filters: Log 8 against E. coli, no viable bacteria were detectable in the outflow water. And we also tell you just as clearly what our filters cannot do: they do not filter nitrates and salt, and only the Squeeze and the Straw filter viruses, not the Selfpress.

OUR FOUNDING STORY

From problem to solution.

Jerome and Laurenz holding black Bachgold® Self press Water Filter in front of mountain peak

Hello, we are Jerome and Laurenz

Two from Zurich. We are united by our connection to nature and the desire to enable other outdoor enthusiasts to experience the same freedom.

On our own expeditions, we experienced how challenging it is to find clean drinking water on the go. Lugging around bulky treatment systems or worrying about water quality: both restrict precisely the freedom that is truly at stake when you're out there.

So, we built a solution: the world's first self-pressing water filter with hollow fiber technology. The goal was the same from the beginning: to enjoy every outdoor adventure without having to worry about the water source.

Today, we're working with a small team from Zurich. Development takes place in Switzerland, while manufacturing is handled by our partner in China. We state this clearly because honesty is the cheapest form of trust.
