Abstract
A piston pressurized water filter activated by the user or external source. The water filter assembly includes a hollow cylindrical water reservoir, a hollow cylindrical piston threaded into the top of the water reservoir, and a water filter threaded into the bottom of the water reservoir. The interior of the water reservoir is sealed by the piston and water filter. When the water reservoir is filled with unfiltered water, the piston can be threaded down into the water reservoir to create sufficient pressure on the unfiltered water and force the water into the water filter. The water filter can include any combination of carbon, ceramic or other filtering material in a block or disk form. Water is forced into the water filter, through the carbon or ceramic filter mass, and into a container that may or may not be coupled to the water filter.
