Abstract: In a method for cleaning a portable filter assembly including an elongated housing and a mouthpiece assembled with an outlet end port of the housing, the mouthpiece is disassembled from a female threaded portion of the outlet end port. A male threaded end connection of a cleaning fluid source is assembled to the female threaded portion of the outlet end port. A pressurized cleaning fluid is supplied from the cleaning fluid source to the outlet end port and through a filter element disposed in a fluid passage of the housing to expel the cleaning fluid and trapped contaminants from an inlet end port of the housing.

Abstract: The present application discloses a filtration device. The filtration device comprises a housing, a lid and a filtration material. The housing comprises at least one outlet hole at a bottom of the housing. The lid is coupled to the housing and comprises at least one inlet hole at a top of the lid. The filtration material is disposed within the housing and comprises a top layer, a particulate treatment layer, an activated carbon fiber layer and a bottom layer. The particulate treatment layer is coupled to the top layer. The activated carbon fiber layer is coupled to the particulate treatment layer. The bottom layer is coupled between the activated carbon fiber layer and the bottom of the housing. A filtration assembly is also disclosed in the present application.

Abstract: A water pitcher with sensing capabilities is provided. The water pitcher includes at least a container adapted or otherwise shaped for retaining water therein, and a cover adapted to cover at least a portion of the container. The water pitcher further includes an indication assembly attached to the container and/or the cover. The indication assembly includes at least a sensor for detecting movement of contents within the water pitcher and/or movement of the pitcher upon expiration of a filter within the pitcher. Upon detecting movement of the pitcher, the sensor is configured to activate an indicator (e.g., an LED) for notifying a user of the expired filter and/or movement of the pitcher during the expiration period of the filter.
