Abstract: A purifier chamber includes a recess formed therein. A bottom plug is in communications with the recess. A filter cartridge, including a mating surface, is insertable into the chamber into an assembled position whereby the mating surface is adjacent the bottom plug. A cartridge ejector is located proximal to the bottom plug and exerts a selective force between the bottom plug and the filter cartridge which is capable of causing axial displacement of the filter cartridge relative to the bottom plug. A contact rod, ejector piston, or spring are illustrated as three possible embodiments capable of accomplishing the desired result of ejecting the filter cartridge from the recess.

Abstract: A filter device includes a first purifier chamber having a first recess. A first filter cartridge is capable of being disposed within the first recess. A second purifier chamber, including a second recess, is included in the filter device. A second filter cartridge is capable of being disposed within the second recess. A contour element is associated with the second filter cartridge, the contour element being configured to resist insertion of the second filter cartridge within the first recess. A mounting portion is formed in each recess and is configured to engage with a mating portion formed on each filter cartridge. The mating portion of each type of filter cartridge is specific as to not be able to be inserted into any recess but those recesses configured for that type of filter cartridge.
