A removable filter cartridge includes a filter housing containing a filter, a seal valve coupled to an open end of the filter housing and configured to removably couple the removable filter cartridge to a filter head. The seal valve has an open position and a closed position sealing the filter housing and is configured to maintain a seal of the filter housing while being disconnected from the filter head. The seal valve includes a first end removably coupled to the filter head and a second end coupled to the filter housing to form a removable filter cartridge. A method of retrofitting a filter housing includes detaching the filter housing from a filter head, coupling a seal valve to the filter housing to form a removable filter cartridge, and removably coupling the removable filter cartridge to the filter head. 一种可拆式过滤器滤芯包含容纳过滤器的过滤器壳体、密封阀，所述密封阀联接到所述过滤器壳体的敞开端且被构形成将所述可拆式过滤器滤芯可拆卸地联接到过滤器头。所述密封阀具有打开位置和密封所述过滤器壳体的闭合位置，且被构形成在与所述过滤器头断开联接的同时维持所述过滤器壳体的密封。密封阀包含可拆卸地联接到过滤器头的第一端和联接到过滤器壳体以形成可拆式过滤器滤芯的第二端。改装过滤器壳体的方法包含从过滤器头拆卸所述
