A health meter with decontamination device for contaminated fluid with a metal casing body with sealable metal lid, inlet port and outlet port, a removable open bucket having a docking lid and a plurality of openings, a hollow tube with an opening connected to an outlet port, a convex reinforcing spacer in the removable open bucket, a compressible decontamination media and a reinforcing seat in the removable open bucket. Contaminated fluid flows into the metal casing body between the removable open bucket and metal casing body through openings in the docking lid into the compressible decontamination media sequentially into the hollow tube and out the outlet port while an inlet and outlet electrode and two sensors in the media communicate with a controller via a network to a plurality of client devices for automatic remote monitoring.

A filter insert, a sample vial incorporating a filter insert, a method of using a sample vial containing a filter insert for chemical analysis, and a sample vial kit including a filter insert. The filter insert includes a cylindrical body having a proximal end, a protrusion extending radially from the proximal end of the cylindrical body and configured to set on the open end of a sample vial, a distal end, a cavity extending longitudinally through the cylindrical body from the proximal end to the distal end, and a filter assembly coupled with the distal end of the cylindrical body.

One or more techniques and/or systems are disclosed for bypass flow filtering. A bypass valve filter includes at least one wall configured to engage a surface of a bypass valve and a filter surface having a plurality of openings between an inside of the at least one wall and an outside of the at least one wall. One or more openings of the plurality of openings have a first size and one or more other openings of the plurality of openings have a second size, wherein the first size is different than the second size to define different levels of filtering. The bypass valve further includes an open end configured to allow fluid flow therethrough and to the plurality of openings.

A water purifier structure includes a container assembly and a buffer unit mounted in the container assembly. The container assembly includes a housing and a cap unit. The housing has a first receiving section and a second receiving section. The second receiving section of the housing is provided with a retaining portion. The buffer unit is mounted in the second receiving section of the housing and includes a positioning ring secured in the retaining portion of the housing, and a cushioning member mounted in the positioning ring. The cushioning member is elastically movable in the positioning ring. When the cushioning member is compressed by a force, the cushioning member is contracted and elastically deformed toward the second receiving section of the housing, to form a buffering force.

A filter device may include a filter housing with a filter housing pot and a cover screwable onto the filter housing pot, and an annular filter element arranged in the filter housing and having an axially protruding pin for closing a run-off channel. The annular filter element may be connected to the cover via a first thread, which may have a dome protruding centrally and axially from an upper end disc of the annular filter element. The first thread may be designed running counter to a second thread arranged between the filter housing pot and the cover.

A filter assembly includes a canister housing closable by a lid and containing a removable and replaceable filter element cartridge. The lid is part of the filter element cartridge and a single unitary component therewith, such that removal of the filter element cartridge also removes the lid, and replacement of the filter element cartridge also replaces the lid.

A removable filter cartridge includes a filter housing containing a filter and a sealing valve coupled to an open end of the filter housing. The sealing valve configured to removably couple the removable filter cartridge to a filter head. An open position allows fluid to flow into and out of the internal volume of the filter housing. A closed position seals the filter housing. A method for retrofitting a filter housing includes removing the filter housing from a filter head, coupling a sealing valve to the removable filter to form a removable filter cartridge, and coupling the removable filter cartridge to the filter head.

A filter assembly includes a manifold having a fluid inlet and a fluid outlet and a filter housing having a filter medium provided therein. The filter medium defines an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing. The filter housing is removably attached to the manifold so as to provide a fluid flow path from the inlet into the inner filter chamber, through the filter medium into the outer chamber and out of the outlet. The filter assembly also includes a valve assembly mounted inside the manifold, and a by-pass channel defined inside the manifold between the fluid inlet and the fluid outlet. The valve assembly comprises a valve spool and a valve spring arranged in engagement with the spool to bias the spool into a first position and to compress, in response to a pressure differential across the valve spool.

An oil filter for a motor vehicle has a filter cartridge which is disposed in an oil filter housing of the oil filter. The filter cartridge has a channel for filtered oil which is surrounded at least regionally by a filter material in the radial direction. At least one through opening is formed in a wall of the channel. An emergence of filtered oil via the at least one through opening into a channel for the filtered oil provided on sides of the oil filter housing is preventable by bringing the filter cartridge into a first position. An inlet into the channel provided on sides of the oil filter housing fluidically connectable to the at least one through opening by bringing the filter cartridge into a second position in which the filter cartridge is shifted relative to the first position in an axial direction.

The filter element includes a filter medium having an axis and forming a channel extending substantially axially, a first and a second end plate, each end plate covering one axial end of the filter medium and being sealingly mounted on the axial end whereby a liquid to be filtered can flow through the filter medium towards the channel and out of the filter element through an opening in fluid communication with the channel, or reversely. The filter element includes a protrusion fixedly secured to the first end plate and extending outwardly from the first end plate, the protrusion being substantially tubular and having a through hole in fluid communication with the first end plate opening, the protrusion forming a female coupling piece of a male-female connector, and a locking member capable of releasably locking a male coupling piece of the male-female connector in the female coupling piece.
