Abstract: A portable drinking device is provided that can be filled with municipal type water, and which will remove impurities (e.g. chlorine) from that water. The portable drinking device is designed so that a person can carry around a single drinking device, fill that drinking device with type water (e.g. from a faucet), and yet have a portable water source more suitable to that person's water quality preferences. The portable drinking device has an integrally contained filtration component, designed for filtering water that is drawn or otherwise delivered from the device through a drinking tube or other delivery mechanism, and in a way designed to ensure that all water obtained from the device is passed through the filtration component to remove the desired impurities.

Abstract: A new and useful approach to cleaning raw water or other raw liquid is provided. A metered amount of stabilized hydrogen peroxide is added to the raw water or other liquid, to clean the raw water or other liquid. In one particularly useful embodiment of the present invention, a portable drinking device is designed so that a metered amount of stabilized hydrogen peroxide can be added to a portable container of liquid, to clean raw water or other liquid in the portable container. Thus, a hiker, military person, or other person who may have to depend on his/her environment for sustenance, and who may not have an available water source other than raw water, has a simple and efficient way of using virtually any available body of raw water as a source, and cleaning the raw water, to provide the person with a portable source of clean water.
