The ÖKO L3 Filtration Kit is a high-performance, lightweight and compact water filter, ideal for drinking water directly from rivers, lakes and other freshwater sources when hiking, camping or in the event of a disaster.

Weighing just 58 grams, the L3 filter can filter up to 1000 liters of water (if rinsed thoroughly after each use). It uses a hollow-fiber membrane capable of removing up to 99.999% of bacteria (such as E. coli) and 99.9% of parasites and protozoa (such as Giardia lamblia and Cryptosporidium), as well as viruses of 0.1 micron or larger.

Discover one of the first pressure-operated water bottles to feature a 0.1-micron hollow-fiber filter, designed to provide extreme levels of filtration.

Idéal pour les voyageurs intrépides et les aventuriers, le filtre L3 est spécifiquement conçu pour traiter les eaux les plus contaminées et inhospitalières. Que vous exploriez des régions éloignées ou des pays où la qualité de l’eau est incertaine, cette paille filtrante améliore la qualité de l’eau selon les conditions testées.

ÖKO filter comparison: L3 vs L2

L3 filter: The extreme solution

Technology

Hollow fibers calibrated to 0.1 micron (1/10,000th of a millimeter).

Performance

What's filtered: Bacteria, E. coli, micro-organisms, parasites, protozoa, giardia lamblia, cryptosporidium, and other contaminants above 0.1 micron.

What passes: Particles smaller than 0.1 microns.

Key benefit

Robust, reliable filtration for highly contaminated or doubtful water.

Recommended for

Extreme situations (muddy rivers, highly polluted springs).

Travel to high-risk countries where drinking water is uncertain.

L2 filter: Everyday versatility

Technology

Hollow fibers calibrated to 1.2 microns + electro-adsorption (technology developed by NASA).
Electro-adsorption: Magnetizes negatively charged particles even smaller than 1 micron (viruses down to 0.01 micron), offering ultra-fine filtration on a broad spectrum of contaminants.

Performance

What's filtered: Bacteria, viruses, pesticides, herbicides, E. coli, micro-organisms, parasites, protozoa, giardia lamblia, cryptosporidium, chlorine, heavy metals, PFAS, disruptors and some particles even below 1 micron (thanks to electro-adsorption).

What passes through: Particles not captured by electroadsorption (mainly mineral salts)

Key benefit

Balanced filtration for non-potable environments.

Recommended for

Daily use on tap.

Filtration of non-drinking water from dubious sources.

1 ère sortie familiale avec gourde au top

Testée la gourde 500ml avec filtre 2 pour la première fois ce weekend en famille. Elle est très légère et c'était très agréable de boire l'eau avec sérénité. Petit regret de ne pas avoir pris une gourde plus grande plus idéale pour une famille de 4 personnes afin d'éviter de la remplir trop souvent.
