A fluid control and processing system for controlling fluid flow among a plurality of chambers comprises a body including a fluid processing region continuously coupled fluidicly with a fluid displacement region. The treatment material has a porosity less than about 200 Coresta units and a sidestream smoke treatment composition. The directional coupler has a coupling line of a length less than \u03bb4 coupled with an output line of the radio-frequency circuit and a terminating resistor connected to one end on the radio-frequency circuit side of the coupling line.
