CARTRIDGE FILTER Russian patent published in 2014 - IPC A61M15/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to respiratory protectors against various aerosols (dust, various viruses, bacteria, etc.). The invention aims at providing higher effectiveness of the separation of aerosols, including those of submicron size. A tampon filter comprises a filter material with elements for placing in the user's nasal cavity. For the purpose of improving the effectiveness of the separation of aerosols, the filter is provided a power supply connected to a corona electrode electrically insulated and gapped from a conductive surface on a filter material electrically connected to the power supply housing. The presented design of the cartridge filter provides corona discharge generation in the air flow supplied into the filter material, and as a consequence, air aerosol particle charging. The electrically charged aerosol particles passing through the pore channels of the filter material are deposited on the earthed surface of the pores of the filter material.

EFFECT: making the filter material electrically conductive, improving the operational efficiency of the filter.
