What is the L2+ filter?
Originally designed for industrial applications, the L2+ filter features a reinforced membrane capable of withstanding extremely high pressures.
Tighter pores: even finer filtration, effectively removing microorganisms and particles.
Adjusted flow rate: instead of 35 seconds to filter 1 liter of water, allow 45 to 50 seconds—a slight trade-off that remains entirely acceptable for field and/or survival use.
Extreme reliability: specially designed for situations where water quality is uncertain.
👉 The L2+ filter is your ideal companion for travel, hiking, survival, or any activity in unfamiliar terrain.

Essential Tips for Effective Water Filtration While Traveling or in Survival Situations
1
Chemical treatment
When traveling to an area where the water quality is questionable, be sure to bring water purification tablets (such as Micropur).
Then filter this water using your ÖKO water bottle to remove the chlorine taste and make it more pleasant to drink.
2
Hygiene is essential
Poorly filtered water may not be due to the filter… but to how you use it:
1- Never dip the cap or pipette into water.
2-Do not put the pipette in your mouth.
3-Always wash your hands before handling.
3
Protect your filters
Bring one or more spare filters: they weigh only 47 g.
Pre-filter very dirty water using a filter sock or a piece of cloth: this protects the 400 pores of your L2 or L2+ filter.
4
Complete with an L3
For trips to areas where the water is particularly hazardous or unknown, opt for enhanced safety with the L3 ÖKO filter.
It’s the perfect complement to an L2 or L2+ filter in extreme conditions. Weighing just 58 grams, it fits easily into any bag.
It's good to have something to drink in an emergency.
It's better to be able to drink it safely.
