Filter assemblies comprising filter cartridges having a first coupling member including at least one lug having an outer diameter, and a support comprising a second coupling member having at least one channel for receiving the lug, the channel having corresponding channel walls, a terminal section including a closed end and a horizontal axis, and an angled section having an open end, the terminal section including a lug retaining section having a cross-sectional area less than the outer diameter of the lug, methods of coupling the cartridges to the supports, and methods of using the filter assemblies, are disclosed. |

1. A filter assembly comprising:
a. a filter cartridge comprising a closed end and an open end; a handle attached to the closed end, at least one filter module interposed between the closed end and the open end; and a first coupling member attached to the open end, the first coupling member having a central lumen therethrough and an external surface, and at least one lug extending from the exterior surface, the lug having an outer diameter; and, b. a support comprising a second coupling member, the second coupling member having a central lumen therethrough and a side wall having at least one channel for receiving the lug, the channel having corresponding channel walls, a terminal section including a closed end and a horizontal axis, and an angled section, angled from the horizontal axis, the angled section having an open end, the terminal section including a lug retaining section having a cross-sectional area narrower than the outer diameter of the lug, the lug retaining section providing resistance as the lug passes through the narrower cross-sectional area;
wherein the filter cartridge is engageable with the support by coupling the first and second coupling members together such that the lug is rotated in the channel from the angled section, through the lug retaining section, into the terminal section, the lug retaining section preventing the lug from rotating out of the terminal section. |
