Our lightest soulbottle, combined with the soulfilter, filters up to 300 liters of water. This makes you just as resilient off-grid as in the urban jungle. Always stay hydrated and safe!
Note: Some external rust is present, but this does not affect safety or function.
Thanks to its durable design and reusable filter cartridges, you can now do without disposable plastic bottles. With the filter, you help to conserve resources and minimize waste. In addition, €1 for every filter sold goes to faircap drinking water projects - a sustainable contribution for people and the environment.

frequently asked questions
The innovative filter technology of the soulfilter is based on a clever interplay of electrostatic adsorption and mechanical filtration . This combination makes the filter particularly effective in removing a wide variety of contaminants from the water - from microorganisms to microplastics and chemical residues.
At the heart of the filter is a crystalline structure that generates a strong positive electrical charge . This charge acts like a magnet to attract negatively charged particles, including:
- viruses
- bacteria
- protozoa and parasites
- Microplastics and fine suspended matter
While mechanical filters only mechanically hold back particles through their pore size, electrostatic adsorption goes a step further: it also captures extremely small contaminants that could otherwise slip through. The filter thus achieves a removal rate of up to 99.99% for harmful microorganisms.
In addition to electrostatic adsorption, the filter uses a nonwoven membrane system coated with activated carbon and nanoalumina .
- Activated Carbon : Known for its ability to remove organic chemicals, chlorine, pesticides and drug residues from water. It significantly improves the taste and odor of the water.
- Nanoalumina : These ultra-fine aluminum particles increase the adsorption power of the filter. They help to bind even the smallest contaminants such as endotoxins.
The filter has a pore size of 1.5 micrometers . This means:
- Larger particles such as dirt, dust and sediments are mechanically retained.
- Microplastics and other visible contaminants stay outside.
A soulfilter cartridge has a lifespan of up to 300 liters of filtered water or about 3 months of daily use (the more polluted the source water, the lower the performance capacity). After this time, the filter performance decreases as the pores and electrostatic material become saturated with impurities. For optimal water quality and safe use, it is recommended to replace the filter every 3 months of continuous use or when the maximum capacity is reached.
particularly safe
The combination of electrostatic adsorption with traditional filtration methods is what sets the soulfilter water filter apart from many other systems. While other filters rely on either mechanical barriers or chemical processes, the soulfilter utilizes the best of both worlds – effective, fast, and environmentally friendly .
This technology makes it possible to drink clean drinking water even in regions with uncertain water quality – whether in everyday life, while traveling or at home.
