Platypus DayCap In-Bottle Filter

Turn your favourite wide-mouth bottle into a fast, reliable water filter. Because of the high speed flow your drinking experience is not much different with or without the filter. Made of field-proven hollow fiber the filter has a flow rate of up to 1L per minute. You can twist the filter off if you only wish to use the cap itself, which is leak-proof and has a tough carry loop so you can clip your bottle on to your pack. Cleaning is easy: just shake the filter with water to clear debris and keep the flow strong.
