Abstract
This application describes a method and apparatus for removing a wide range of particles from a source of gas flow or separation of particulates from dust, mist, or vapor generating devices. An innovative use of open porous materials, which causes little pressure drop, in combination with an electrostatic grids structure is described. The apparatus is capable of removing particulates in the size range 0.01 to 1 micrometer with efficiencies as high as 99.5%. A key feature of the apparatus is that the air to be purified flows parallel to the filters instead of through them, which results in very low power consumption.
