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.

The invention relates to a method for degassing a fluid comprising the following steps: supplying, at the inlet of a reactor comprising at least one microfluidic conduit, a fluid which can comprise at least one dissolved gas; then causing the fluid to flow through the reactor, the at least one conduit comprising a portion having a reduced hydraulic diameter, and the flow being set such that bubbles are generated by micro-cavitation, the fluid then comprising a liquid phase and a gas phase, then allowing the at least partial transfer of the at least one dissolved gas present in the fluid of the liquid phase to the gas phase; separating the liquid phase and the gas phase; and recovering the liquid phase to obtain the degassed fluid, the method not involving the application of ultrasound to the fluid between the step in which the fluid is supplied to the reactor and the step of separating the liquid phase and the gas phase.

In one embodiment, a method for decreasing a humidity level in an information handling system includes: receiving, by a sound field chamber, an incoming airflow, the incoming airflow having a humidity level corresponding to an amount of water vapor in the incoming airflow; identifying, by a humidity controller, the humidity level of the incoming airflow; determining, by the humidity controller, that the humidity level is greater than a threshold humidity level; and in response to determining that the humidity level is greater than the threshold humidity level: causing, by the humidity controller, a sound source of the information handling system to generate a sound field within the sound field chamber, the sound field comprised of sound waves, the sound waves causing an acoustic agglomeration of the water vapor, the acoustic agglomeration causing the humidity level to decrease.

An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.
