Disclosed is a portable air filtration system for removing contaminants from room air. In one embodiment, the air filtration system includes a power supply and an air blower module electrically connected to the power supply. The air filtration system further includes an ionization module engaged with the air blower module and including a first control grid and a high voltage grid electrically connected to the power supply. The air filtration system further includes a filter module removably engaged with the ionization module. The filter module includes a filter and a second control grid. Engagement of the filter module and the ionization module creates an electrical connection between the second control grid and the power supply. Activation of the air filtration system creates a first ionization field between the high voltage grid and the first control grid and a second ionization field between the high voltage grid and the second control grid. There is also disclosed a method of assembling the air filtration system.

Multi-port valve assemblies with, typically, two-piece housings are disclosed. Particularly useful in connection with swimming pools and associated water pumps, the assemblies avoid reliance on an elongated handle to effect rotation of the internal structure of the valve. Instead, the assemblies utilize a knob&mdash;which users need not lift&mdash;coupled to a post in which an elongated slot is formed. Doing so avoids breakage problems associated with use of elongated handles while reducing wear of internal seals. Each valve assembly additionally may include a cam having non-semicircular, asymmetrically-shaped recesses into which followers attached to a shaft passing through the elongated slot are received.
