A water filtering pitcher with a pitcher with a top, a base and an inner wall surface extending between the top and the base to define an internal volume. A filter adapter is positioned within the internal volume of the pitcher, configured to couple to a water filter, and movable between a first position closer to the base and a second position closer to the top. At least one bias member configured to bias the filter upward is positioned between the filter adapter and the pitcher base. When a water filter is received through the top of the pitcher to the filter adapter and water is filtered from above the filter adapter through the water filter and into the base of the pitcher, the at least one bias member biases the filter adapter and water filter from the first position toward the second position.

A portable drinking water filter system, such as a pitcher, having a sleeve and a floatable body including a filter opening configured to receive a water filter, the floatable body having a seal extending outward from an outer surface of the floatable body. The floatable body is disposed in a sleeve cavity such that a body seal engages the sidewall and restricts water from passing between the floatable body and the sidewall. The seal is configured to create friction with the sidewall, wherein the friction created when the floatable body rises in the sleeve is different than when the floatable body lowers in the sleeve. The friction created when the floatable body rises in the sleeve is greater than when the floatable body lowers in the sleeve, allowing the floatable body to auto-retract toward a cavity base without burping.

The disclosed technology includes pre-filter system that can include a filter portion comprising pipes, elbows, and tees. The pipes can include apertures. The pipes, elbows, and tees can be positioned such that a first end of a first group of neighboring pipes can be fluidly connected to form a column of fluid connection and a second end of a second group of neighboring pipes can be fluidly connected to form a row of fluid connection. The apertures of at least some of the pipes can be covered with a mesh netting. The pre-filter system can include an airtight float portion. The float portion can be attached to the filter portion to provide a predetermined amount of buoyancy to the pre-filter system.

A water filtering system includes a support with pontoons to provide buoyancy and a suction pipe; a plate connected to the pontoons and suction pipe; and a wheel bearing shaft. A venturi system includes a venturi suction pipe and a discharge pipe. A screen assembly to engage with the plate around the venturi system, having a filter drum; and a wheel bearing assembly engage with a wheel bearing shaft to secure the screen assembly in place; buckets are mounted to the closed end; and a pump engaged with the suction pipe. The pontoons and the suction pipe extend into the filter drum; water is pulled through the venturi suction pipe and further pushed to the discharge pipe and the split pipe to fall out and into the buckets; the filter drum to rotates; and water is dumped from each of the buckets through the screen.
