Abstract
An air treatment system has a removable and replaceable cartridge, the cartridge having a cylindrical plastic canister, and having a liquid-permeable vaporizing element disposed in the canister. The canister is located on one side in a cradle inside a housing where air flow is controlled between inlet and outlet ports by a pivoting frame member. A slider is moved up and down outside the housing to simultaneously move a pair of arms inside the housing into closed, partially open or fully open positions relative to the inlet and outlet ports. The canister has ports of special configuration and a baffle is placed in the canister to assist radial air flow and assure that air flows over the coiled air vaporizing element.
