Smart IoT energy saving sound wave air filter system and use for air purifiers and a method of air filtration thereof

A method of air filtration, comprising:

• capturing, via a filter media, one or more impurities from air;
• generating, via one or more sound wave generators, sound waves to be propagated into the filter media, wherein propagation of the sound waves into the filter media facilitates in increasing travel distance of the one or more impurities inside the filter media thereby enabling the filter media to intercept the one or more impurities;
• generating turbulence in the filter media thereby enabling the filter media to enhance the capturing of the one or more impurities based on enhanced turbulent diffusion effect and generating frictional electrostatic charges on the filter media thereby enabling the filter media to attract the one or more impurities;
• detecting, via a plurality of sensors comprising a combination of a voltmeter, an ammeter and a pressure sensor, a pressure before and after air enters filter media in order to determine a pressure drop;
• determining, via the plurality of sensors, an AHU to be functioning or malfunctioning;
• and
• controlling, via an IoT, frequency of the sound waves generated by the one or more sound wave generators, and the AHU to control rotational speed of at least one fan positioned either before or after the filter media in order to maintain the pressure drop based on value provided by the plurality of sensors.

An air filtration apparatus, comprising:

• an air filter media;
• one or more sound wave generating devices attached at one or more sides of the air filter media, wherein the one or more sound wave generators generate sound waves to be propagated inside the air filter media thereby enabling the air filter media to intercept and filter one or more impurities from the air;
• a frame securing the air filter media and the one or more sound wave generating devices on right top and left bottom sides openings;
• a plurality of sensors comprising a combination of a voltmeter, an ammeter and a pressure sensor configured for detecting a pressure before and after air enters filter media in order to determine a pressure drop, and further the plurality of sensors is also configured to determine an AHU to be functioning or malfunctioning;
• at least one fan positioned before or after the air filter media;
• an IoT configured to control frequency of the sound waves generated by the one or more sound wave generators, and the AHU to control rotational speed of the at least one fan in order to maintain the pressure drop based on value provided by the plurality of sensors;
• and
• a power supply to power the one or more sound wave generators, the IoT, and the at least one fan.
