The PAANY! Filter could replace about 1000 ltr. mineral water bottles per annum! Apart from that, here are some benefits at a glance: Light - weight, portable 750 ml bottle with integrated PAANY! Membrane filter. Easy to fold and store in hand bags, luggage or backpacks. Your ideal companion for leisure or travel. A fold-able, easy-to-use bottle with high-tech filter. Drink straight from the bottle and enjoy every sip of safe water. The filter can remove up to 99,9999% of Bacteria, Protozoa and particles, ensuring safe drinking water. The filter can be used for tap, well, river water, water falls, ponds and lakes. However, care has to be taken not to use the filter in overly dirty water sources (e.g. damps, drains, overly dirty river or ponds) The filter will work there, but will clog very fast and will be unusable in a much faster time Our PAANY! filter is supplied in silicone water bottle or flexible pouch. The silicone bottle can be used for an extensive period of time. You save at least 1000 liters of packaged drinking water bottles and therefore support your environment! Our ideas have also been valued by the Greentec Awards in Germany, one of the biggest environmental awards worldwide.
