A new water filter system which compares very favorably to other such systems in terms of cost, ease of use and weight. Filter weighs only 53g. Cleaning plunger 30g. Straw 3g. 0.5 litre pouch 23g. Total weight of system 109g (All weights are mine and not manufacturers weights). Sawyer mini comes with a 100,000 US gallon (378,540 litre) guarantee according to their website.
Please check the Sawyer website to see if your particular requirements for a water filter system is provided by this product, particularly if using outside of the UK. UPDATE – it was pointed out to me that to filter out viruses, which tend not to be a problem in developed countries, you need to use a filter size of 0.02 microns. A useful page is here
