Pump & Bottle Filters

Pump Filters
All hand pump filters have the following characteristics in common:
(a) hand crank lever for pumping water,
(b) a water intake hose that draws water from the water source (such as a stream),
(c) a replaceable filtration element or cartridge through which the water is filtered,
(d) a water hose or adapter that outputs filtered water into a water bottle or reservoir.


Most pump filters work the same way:

The hand crank lever is used to pump water through the intake hose;
The water is pulled from the intake hose through a replaceable filtration element or cartridge;
The filtered or purified water then outputs through a hose or bottle adapter for collection into a reservoir or water bottle.
