Abstract
A water filter system with a filter housing, a filter media, a filter coupling, and a dynamic seal. The filter housing has a top plate and a bottom plate which are both water-permeable, as well as a cavity between the top plate and the bottom plate. The filter media is within the cavity of the filter housing and extends through the bottom plate of the filter housing. The filter coupling extends upward from the top plate and is configured to attach to a float with at least one air chamber. The dynamic seal is coupled to the filter housing along a perimeter of the filter housing and is configured to extend beyond a perimeter of the float, maintain contact with a wall of a water container, and restrict water from passing between the dynamic seal and the wall of the water container.
