“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.”

“I used the Bachgold water filter for the first time while canoe trekking in Sweden and I'm thrilled. The filtered water tasted great and all our water bottles were filled quickly. Afterwards, I always air-dried the filter in a 'vegetable bag'. I can only recommend this product - and the great support with 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.”

When do I need to change the filter?
After 1,500 liters of filter performance at the latest – approx. 2,500 applications. Replace if the water flow slows noticeably or if the water tastes strange.
Does the replacement filter fit all Selfpress models?
Yes — fits in Bachgold Selfpress (500 ml). For Selfpress XL (800 ml), you need the XL replacement filter.
Should I buy several at once?
It makes sense if you use Bachgold regularly. The Refill Pack Selfpress offers 3 replacement filters in a bundle — cheaper than buying 3 single packs.
How do I store interchangeable filters?
Store in a dry, cool place away from light. Unopened replacement filters will last several years in their original packaging.
