Here's how
This is how Bachgold works.
Three filters for three situations. Press, squeeze, or suck – drinking water directly from the source.
-
01
Add water.
From a lake, stream, or puddle. Fill the tank — at home, by the campfire, or on the go.
-
02
Presses.
Hollow-fiber membrane filters when water is pressed through it. Bacteria, protozoa, and suspended solids remain inside.
-
03
Clean water.
99.99% bacteria and protozoa out. Drinkable in seconds – no chemicals, no waiting time.
-
01
Direct to source.
Dip bottle in stream or puddle. Close cap, done – no setup time.
-
02
To squeeze
Squeeze by hand. Water flows through the Squeeze — filtered as it passes through.
-
03
Light & Compact
after filtering, roll it up and put it in the bag. Done.
-
01
Find source.
Mouth to straw, pull. Filters directly, not a drop unfiltered.
-
02
Process.
Puddle, stream, pond — no matter how murky.
-
03
Bushcraft mode.
Ultralight, no container needed. Every source becomes a drinking station — emergency kit, day trip, hike-light.
See how it works
Scoop. Press. Drink.
Drinkable in 10 seconds.
From the puddle, if need be.
Filters 99.9999% of all bacteria, microplastics, and heavy metals.
LABORATORY VERIFIED · NSF P231
Independent Laboratories
Our water filter was tested by an independent laboratory in accordance with the requirements of NSF P231. This involves testing the filter's reduction in percentage against microorganisms, using E. coli as an example.

“After initial difficulties pulling the filter unit out of the housing on the first attempt (I got help from my neighbor), I am now on a trip in a national park in Costa Rica, and the bottle is exactly what I need here! Single-use plastic bottles are prohibited in the parks! Refilling is now possible without any problems!”

“Tested on the Mittelland Canal 👍 .... In 2024, on the Camino, where others got sick from spring water, I was able to enjoy the water without a second thought. Yesterday, I tested the filter in my water barrel — the water has been sitting in there for quite some time. Perfect filter, I love it 🤘 Never another one!”

“I am completely satisfied with the filter! It has already accompanied me through Finland and on some routes through Germany. Filtering is surprisingly easy, and the filtered water is definitely drinkable! However, a slight aquatic taste always remains; this is only really pungent in standing waters with a lot of algae and suspended solids.”

“Wild camping on our West Highland Way tour. We took water from rivers and lakes and filtered it. Everything went great — nobody had stomach problems 😉”

“The operation is very stiff; it could be eased by improving the grip on the upper part. The water level indicator is hard to see. But otherwise, I am satisfied.”

“So far, everything is great, shipping was super and fast. I haven't tried the bottle yet — an indicator on the bottle would be good, so you know when you need a new cartridge. I will post a new review on my Instagram and on the website once I've used the bottle.”

“The lettering was no longer nice after just one week of use (see photos). By now (2 weeks in Madeira) it is no longer visible at all. The bottle is also very prone to scratches and the "rubber" behind the lid has small cracks. I really expected more for the price. I only drank from sources 3 times and had no problems with the water. The purpose was at least fulfilled.”

“We were hiking long-distance in Lofoten and bought Bachgold water bottles to have water everywhere. We were super happy with our choice. Bachgold delivers on its promise. Super fast and easy access to the best water! We love it! :D”

“I tried out the Bachgold water filter for the first time while canoe touring in Sweden and I'm thrilled. The filtered water tasted great and all our water bottles were filled quickly. Afterwards, I air-dried the filter each time in a 'vegetable bag'. I can only recommend this product — and their great support for any questions!”

“We took our filters to northern Sweden and also filtered all kinds of water with them in Germany and never had any problems afterward. When filtering, one should not press the filter into the container too hastily and take one's time. I can only recommend a purchase.”

“I immediately chose the right water trough (picture) and was very satisfied with the result. The water was clean, tasted good, and was well-tolerated.”

Founding Story
Our founding story.
Hello. We are Jerome & Laurenz — two people who live in Zurich and prefer to be outside rather than inside.
2019. Four days of trekking in Nepal. On day three: a stream, milky and murky with glacial sediment. Our straw filters from the outdoor store clogged after three sips.
We powered through. But back home, the question remained: Why isn't there an outdoor filter against bacteria — mechanical, in seconds, without chemicals, without a pump?
There wasn't one. So we built it.
In 2022, the Selfpress went into production — the world's first press filter with a hollow fiber membrane. 99.9999% of all bacteria out, in under ten seconds. Exceeding NSF P231 standard.
But bacteria were just the beginning. Outside of Europe, the problem is different: viruses. Too small for classic hollow fiber.
So we kept building. Today, Squeeze and Straw additionally filter 99.999% of all viruses. Three filters, one mission: Drink from any source. Safely.
