Description
The ÖKO 1-litre (34 fl oz) filter bottle lets you drink fresh water directly from a spring, river or lake. Designed for hiking, bivouacking, travel and expeditions, it filters water instantly when the bottle is squeezed — no chemicals, no waiting time.
The filter combines mechanical filtration with electro-adsorption technology. Activated carbon-impregnated fibres capture particles down to 1.4 microns, while electro-adsorption targets finer contaminants. The system removes 99.99% of viruses, bacteria and protozoa, while reducing heavy metals, pharmaceutical residues and microplastics found in fresh water.
The filter has a maximum capacity of 400 litres (88 gallons) and a flow rate of up to 2 litres (0.5 gallons) per minute. Its lifespan can be tracked using the free Öko Counter app, which logs refills and helps you anticipate when to replace it. Increased resistance when squeezing the bottle also indicates the filter is nearing the end of its life.
Weighing just 172 g (6.1 oz), this water bottle is easy to carry despite its 1-litre (34 fl oz) capacity. The wide opening makes filling simple, and the robust polypropylene body is BPA-free and free from toxic agents. The bottle can be washed by hand or in the dishwasher after removing the filter.
Its key advantage over a standard filter bottle lies in its electro-adsorption technology, which targets viruses and a wide range of fine pollutants while maintaining a fast flow rate and immediate usability.
