Platypus DayCap In-Bottle Filter

For those times you question the water source, this clever cap turns your favourite water bottle into a filter bottle. Simply screw the DayCap onto your wide mouth water bottle and your ext sip will be filtered. Using hollow fibre filtration, a method that is trusted all over the world, this cap removes bacteria and protozoa from your water. When it is time to clean your filter, simply shake your bottle. Unlike back flushing, the shake-to-clean method doesn’t have to be done with clean water, so you can clean your filter anywhere.
