A filter apparatus includes a filter housing having a gas treating enclosure portion and a hopper portion disposed below and open to the gas treating enclosure portion. The gas treating enclosure portion encloses a plurality of spaced apart filter cells which are to be filled with granulated gas treating material. The filter cells have open bottoms open to the hopper portion. A gas treating material conveying channel is disposed within and extends across the hopper portion of the housing proximate the bottom thereof. The interior of the channel is open to the interior of the hopper portion only intermittently along the longitudinal sides of the channel. Further, a conveying gas inlet aperture is formed through one wall of the hopper portion opening into the channel at one of its ends, and a gas treating material and conveying gas outlet aperture is formed through the opposite wall of the hopper portion opening into the channel at the other of its ends.
