IMPROVED FILTERING MATERIAL FOR AIR PURIFIER BASED ON MATERIAL POLARISED WITH ELECTRIC FIELD Russian patent published in 2010 - IPC B01D39/10 

FIELD: technological processes.

SUBSTANCE: invention is related to air purification systems. Air purifier and filtering material for air purifier on the basis of material polarised by action of electric field are proposed, and material includes two layers of dielectric material and air impermeable net with higher resistance arranged between layers of dielectric with lower resistance. Filtering material may also contain filtering layer of mixed fibers, which contains fibers on various sides of triboelectric scale. Filtering material may also include a layer of dielectric material with relatively higher density, which is followed by a layer of dielectric material with relatively lower density.

EFFECT: invention makes it possible to expand assortment of air purifiers of various purpose.
