I would have to say that its not a matter of which is used more, since each one has its uses, strengths and weaknesses, in comparison to the other.

Filter Bag Collectors

Sometime referred to as a Baghouse, these collectors are the most widely employed, and with good reason. Fabric Collectors offer the widest range of applications, and if operated and maintained properly, will result in the best overall performance. Ideal for the use of wide range of industries including but not limited to: Power Generation, Industrial Processing (Pharmaceutical, Mineral, Chemical, Rubber, Food, etc) Woodworking/Milling, Steel and Metal Production and Processing.

Cartridge Collectors

Ideally suited to capture certain special shaped and sized dusts (granular shaped & less than 50 microns) and low grain loading levels (less than 5 grains per cubic foot). Certain dusts require minimal flexing of the media during the cleaning process; thus, cartridge collectors will work satisfactory on these particular products. Uses include but are not limited to: grinding or sandblast applications, welding fumes, laser and plasma cutter fumes, graphite, pharmaceutical powders, and fine chemical powders.
