The robust bottle holds 0.65 litre filtered water and is equipped with a fold-up bite valve and snap hook. The 2-stage filter cleans up to 4000 litres of contaminated water and contains no chemicals, batteries or moving parts like many other water filters on the market. The two-stage filtration process removes bacteria and protozoa and reduces organic chemicals and chlorine. The hollow fibre membrane filter should be replaced after approx. 4000 litres. The replaceable activated carbon capsules, removes bad taste, chlorine and organic chemicals. These capsules are individually replaceable and should be replaced after 100 litres or 3 months after first use.
