METHOD, DEVICE AND SYSTEM FOR AIR FILTRATION AND CLEANING Russian patent published in 2024 - IPC B01D46/26 B01D46/52 

FIELD: air filtration.

SUBSTANCE: air filtration device includes one or more rotating pleated air filter and a motor for rotating the pleated air filter. The air filters are cylindrical in shape and are additionally designed in accordance with the relation Gu = f_h*p_r/(2*r_o*ε^∧1/4)>0.8, where f_h is the height of the filter, p_r = (r_o-r_i)/(p_s), p_s is the distance between the corrugations, which is the distance between two adjacent vertices of the corrugations at the inner radius, r_i - internal radius of the filter, r_o - external radius of the filter, ε – ASHRAE filter efficiency.

EFFECT: ensuring the filtration of sufficient volumes of air while occupying less space, less energy consumption and lower noise levels, ensuring high efficiency.
