drinking water quality worldwide

Who doesn't know this dilemma? When on vacation, you almost always have to buy water because tap water is not recommended for drinking in over 200 countries. And we actually want to save plastic!
To make this a thing of the past, we have developed the soulfilter.

Because our mission is to reduce plastic consumption and give people access to clean drinking water.

The water filter for soulbottles reliably filters out bacteria, viruses, chlorine, dirt and microplastics – more than most commercially available filters. And all of this without removing minerals.

innovative

Made in Finland

Together with our experienced partner Faircap, we have developed a unique filter for our drinking bottles that filters out not only viruses and bacteria, but also sediments, pesticides and heavy metals. The ultra-fine filter material comes from Finland and has been independently checked and tested several times.

silicone, polywas...isn't that plastic?

The unfiltered truth: yes, we admit it - for the very first time, we have developed a product with plastic. We produce our products as sustainably as possible , we are really ambitious about that.

However, in order to make the soul filter hygienic and functionally flawless, it must be made of plastic: the filter cover is made of polypropylene*, and the mouthpiece and hose are made of silicone. Both materials are free of harmful substances and safe to use in contact with food. In addition, only the cartridge needs to be changed when the filter has reached its maximum filter performance.

Even though we use plastic in production, you save 300 times more plastic** with the soulfilter than if you were to buy bottled water from plastic bottles!

the work of faircap

Faircap is a social enterprise that has come up with a special model: Faircap reinvests the money it earns in the research and development of filter systems for the humanitarian sector.
In addition , for every soulfilter sold, 1 € is donated to Faircap. This allows NGOs to purchase filter systems at a very reasonable price and reach many more people with limited resources.

Our previous soulfilter productions were used to finance the mold for the new Faircap Family Filter Kit. The first prototype is in Niger and a further 2,000 kits are to provide safe and easy access to clean drinking water in Niger, Sudan, Mali and Mauritania.
