A multi-layer structure honeycomb filter for dust collection, comprising one or more filter layers formed on the surface of a porous base material having a honeycomb structure, wherein the pressure loss of the base material is 150 to 700 Pa when the filtration flow velocity of the filter is 1 m/min, and the pressure loss of the filter layers of at least one layer is 50 to 300 Pa, whereby a capture efficiency can be increased and the pressure loss can also be reduced. |
