Claim:
1. A dual filter dual integrity test conduit assembly comprising: A first filter unit comprising a filter housing defining an entry port, an exit port, and a filter cavity in fluid communication therebetween, a filter membrane spanning said filter cavity such that said filter membrane provides filtered isolation between said entry port and said exit port; A second filter unit comprising a filter housing defining an entry port, an exit port, and a filter cavity in fluid communication therebetween, a filter membrane spanning said filter cavity such that said filter membrane provides filtered isolation between said entry port and said exit port; First and second upstream valves, each of said first and second upstream valves including a valve body defining a first and second input port and an output port, each said first and second upstream valve further including a stopcock movable between a first position placing said first input port in fluid communication with said output port while fluidly isolating said second input port from said out port and a second position placing said second input port in fluid communication with said output port while fluidly isolating said first input port from said output port, wherein said output port of said first upstream valve is placed in fluid communication with said input port of said first filter and said output port of said second upstream valve is placed in fluid communication with said input port of said second filter; First and second downstream valves, each of said first and second downstream valves including a valve body defining an input port and a first and second output port, each said first and second downstream valve further including a stopcock movable between a first position placing said first input port in fluid communication with said first output port while fluidly isolating said second output port and a second position placing said input port in fluid communication with said second output port while fluidly isolating said first output port, wherein said input port of said first downstream valve is placed in fluid communication with said output port of said first filter and said input port of said second downstream valve is placed in fluid communication with said output port of said second filter, and wherein said first input port of said second upstream valve is placed in fluid communication with said first output port of said first downstream valve; and First, second, third, and fourth integrity valves each comprising valve body with an input port and an output port, each said integrity valve including a shunt mechanism moveable between a first position providing fluid communication between said input port and said output port and a second position fluidly isolating said input port from said output port, wherein said output ports of said first, second, third, and fourth integrity valves are placed in fluid communication with said second input port of said first upstream valve, said second output port of said first downstream valve, said second input port of said second upstream valve and said second output port of said second downstream valve, respectively.
