  • Smart IoT energy saving sound wave air filter system and use for air purifiers and a method of air filtration thereof
    Patent number: 11708986
    Abstract: An air filter and a method of air filtration using the air filter are described. The air filter may comprise a filter media adapted to capture and filter one or more impurities from air. Further, one or more sound wave generators are attached at one or more sides of the filter media. The one or more sound wave generators generate acoustic waves to be propagated into the filter media. The air filter may further comprise a plurality of sensors positioned before the filter media and after the filter media. Further at least one fan is positioned before or after the filter media. Further an IoT is configured to control frequency of the acoustic waves generated by the one or more sound waves generators, and interconnected with power signal control panel parallel, AHU to control rotational speed of the at least one fan based on value provided by the plurality of sensors.

  • Acoustic aided air filter and a method of air filtration thereof
    Patent number: 11383192
    Abstract: An air filter and a method of air filtration using the said air filter are described. The air filter may comprise a filter media layer adapted to capture and filter one or more impurities from air. The air filter may further comprise one or more acoustic wave generating means attached at one or more sides of the filter media layer. The one or more acoustic wave generating means may generate acoustic waves to be propagated into the filter media layer. The propagation of the acoustic waves into the filter media layer may facilitate the filter media layer to enhance the filtration efficiency of the air filter. The air filter may further comprise a pre-programmed chip to control the frequency of the acoustic waves generated. Further, air filter may comprise a battery adapted to supply power to the one or more acoustic wave generating means and the pre-programmed chip.
