  • Patent number: 7413653
    Abstract: A portable filtered drinking water system for removing undesirable tastes, odors, and contaminants from potable water to improve the quality of the water for drinking or consumption. The device consists of a container that holds the potable water and has an air tight screw on cap. Mounted on the cap is an opening for a screw-in hand air pump to create air pressure inside the container and an opening for a faucet for dispensing filtered drinking water. Pulling up and pushing down several times on the hand air pump creates air pressure in the container that forces the potable water through a water filter located inside the container and up to a faucet to be dispensed when a lever is pushed down.
