A water filter cartridge has a cap with radially oriented first and second (either inlet or outlet) flow channels on first and second generally cylindrical portions. First and second seals encircle the first flow channel on the first portion and third and fourth seals encircle the second flow channel on the second portion. The second and third seals form a void volume during use which may be accessed by a vent path to eliminate moisture or to test for or indicate leaks. The radial flow paths reduce axial, push out forces on the filter cartridge and allow smaller locking tabs to be used. The first seal forms a top void volume during use which may be accessed by a vent path to eliminate moisture or to test for or indicate leaks.

Portion of an air treatment unit

Air-treatment apparatus and methods are disclosed that are especially suitable for treating the air in a room or other dwelling or working space. An apparatus embodiment of the subject apparatus includes a housing having air-intake and air-output openings. A gas-filter assembly inside the housing receives air entering the air-intake opening and includes a dual-media filter element having a matrix of fibers to which particles of activated carbon are adhered at mutual points of contact without using an extraneous binder. As air passes through the gas-filter assembly, the carbon particles adsorb odor compounds from the air. At least one electrostatic 3-dimensional (E3D) filter assembly downstream of the gas-filter assembly includes a respective charging element sandwiched between dielectric-fiber filters sandwiched between two respective electrically conductive screens. The screens are electrically grounded while the charging element (which is conductive) is connected to a source of high-voltage DC power. The resulting charges on fibers of the dielectric-fiber filters polarize and attract particles in air passing therethrough.
