FILTER UNIT AND CLEANER PROVIDED WITH SAME

摘要

The invention provides a filter unit with low initial pressure loss and high dust-releasing properties and shock resistance. The invention is a filter unit provided with: a filter material having a porous fluorine resin membrane and a gas-permeable support material laminated on at least one surface of the porous fluorine resin membrane; and a frame that supports the rim of the filter material. In the filtration region of the filter material of the filter unit, the ratio of the area of the region where the porous fluorine resin membrane and the gas-permeable support material of the filter material are bonded together with respect to the area of the filtration region is 10% or less.
