Öko Filter

Designed for both men and women, the Öko Filter is ideal for anyone who uses a hiking or trail running water bottle and wants to continue drinking purified water throughout their outings. This replacement filter performs at its best in both outdoor and urban settings, extending the lifespan of your ÖKO Original water bottles. Its NASA-developed electro-adsorptive filtration technology and activated carbon provide thorough purification, while its compact cartridge is easy to pack with your gear. With a filtration capacity of up to 400 liters, it’s a reliable companion for all your adventures.

A compact replacement filter for your ÖKO Original water bottles

The ÖKO Filter is designed as a replacement cartridge for ÖKO Original water bottles, regardless of their size or color, allowing you to keep the same bottle while simply replacing the filter element. Compatible with all versions of these water bottles, it makes it easier to stay hydrated while hiking, trail running, or in your daily life, without changing your usage habits. Measuring 5.7 cm x 5.7 cm x 5.7 cm and weighing just 34 g, it takes up minimal space inside the water bottle and adds only a minimal bulk to an already packed backpack. This compact design is particularly well-suited for outdoor use where every gram counts, while still offering a filtration capacity of up to 400 liters, depending on water quality.

Advanced filtration technology for reliable water

At the heart of the Öko Filter lies an electro-adsorptive filtration technology developed by NASA, designed to purify water with a high degree of efficiency. This technology, combined with natural mineral fibers and activated carbon, captures and retains a wide variety of contaminants to provide safer water during your outdoor activities. The filter demonstrates high performance in a COFRAC-accredited laboratory, with removal rates of 99.9999% for Raoutella terrigena, 99.998% for Cryptosporidium, 99.98% against viruses, 99.9999% against Giardia lamblia, and 99.94% against E. coli. These precise figures provide technical transparency for discerning users who are concerned about the quality of the water they consume while hiking, traveling, or in situations where the water source is not fully controlled.

Materials and Filtration Durability for Outdoor Use

The Öko Filter uses a combination of natural mineral fibers and activated carbon—materials chosen for their ability to adsorb numerous particles and compounds present in water. This configuration combines water purification with ease of use, minimizing inconvenience for users who want to rehydrate quickly in the field. The cartridge has a stated filtration capacity of up to 400 liters, a figure that depends directly on the quality of the treated water, allowing you to adjust the replacement frequency based on the type of environment you’re traversing. When hiking or trail running, where water sources vary, this capacity provides useful guidance for planning your outings and determining when to replace the filter based on your activities.

The Öko Filter is thus a compact and high-performance replacement cartridge, designed to extend the purification function of your ÖKO Original water bottles thanks to NASA-developed electro-adsorptive filtration technology and materials made from natural mineral fibers and activated carbon.
