A plurality of air data may be collected by a sensor within a data center. The plurality of air data is received by a processor. At least a portion of the received plurality of air data corresponding to at least one zone within the data center may be determined to satisfy a threshold. Coordinates of a geographical location associated with the zone that includes the sensor may be transmitted to a robotic filter. The robotic filter can be dispatched to the transmitted geographic location to filter the zone.

An air conditioner includes a controller that controls a driving unit of the air conditioner. The controller includes a determination unit that determines necessity of a contaminant reduction operation of the air conditioner based on whether the air conditioner is in a non-cooling operation period, and a setting unit that sets a condensation operation condition for forming condensed water on a surface of an indoor heat exchanger of the air conditioner. The controller performs the contaminant reduction operation of the air conditioner based on a necessity determination result of the determination unit in accordance with the condensation operation condition set by the setting unit.

This present application discloses use of a hydrogen peroxide solution for a filter media cleaning and sanitizing system which is designed to dispense the solution to disinfect an air filter. The system is attached to an existing air filter, allowing the system to lightly mist the filter media with the solution. The invention also adjusts the ions in the air system to eradicate germs, bacteria, viruses, and other airborne pathogens, and functions as a sanitization method for any type of air or HVAC system.

A system is described to protect a person from exposure to pathogens in breathing. A control device which can be an adjustable or removable filter, a valve to switch air sources, added substances interruption of the air stream is controlled by a determination made by a machine learning system with a machine learning model usually implemented as a neural network. The determination is made on the basis of training of the model which can be one or multiple stages with one stage in a large server not in real time and another stage in a field device which uses sensors and other information sources to acquire data to make a decision concerning the relative risk of various circumstances. Conditions detected include presence of other persons, level of activity of the protected person and many other factors concerning the surroundings, activity and history of the protected person.

An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

The present invention provides a smart air filter blockage detection and alert communication system for use with filters in air circulation systems such as HVAC, vehicles, server systems, and dryers. The system attached to the frame of a filter comprises a light source, a light sensor, two actuators and a control unit. The control unit based on a stored program or an external command activates the actuators to place the source and the sensor devices attached to the two arms of the actuators on the two sides of the filter membrane. The sensor measures the light intensity transmitted through the filter. The control unit upon receiving the intensity data determines the filter blockage level and communicates alert to the user when the blockage exceeds a predetermined value. The system uses a 4G or a 5G IoT network capability for data collection and communication with servers and user devices.
