Abstract
A canteen especially useful in contaminated environments includes a hollow watertight container adapted to hold a quantity of a drinking fluid and a filter device extending into the container through an opening at the top. The filter device comprises an elongated tubular member having disposed therein an air filter for filtering the air entering the container and a water filter for filtering the drinking fluid exiting the container. In using the canteen, air is drawn into the container through the air filter and drinking fluid is drawn out from the container through the water filter by suction.
