초록

An apparatus for producing drinking water from bacteria contaminated cold water is provided. The cold contaminated water is placed into a flexible collector having a sub-micron porous filter in the bottom. When the flexible collector is squeezed, the pressure forces the contaminated water through the filter and into a holding chamber. The drinkable filtered water is removed from the holding chamber through a sterile exit opening.
