Water Filter Bottle for CRPF Jawans is a manual water purifier designed for soldiers on the march in remote areas. The bottle contains a pump-based water filter designed to be lightweight, durable, and soundless. The bottle’s base houses its water filter and pump. When the soldier reaches a contaminated water source, he opens the base and immerses the filter in the water source. He then hand-cranks to pump clean, filtered water into the bottle. After pumping, he removes the filter from the water source, winds it up and secures it in the base. He snaps the base back onto the bottle and opens the cap to drink.
