An air conditioner for air pollution prevention includes a main body, a blower, a filtering and cleaning assembly, and a gas detection module. The blower is disposed in the main body to guide air convection and generate a flow-guiding path. The filtering and cleaning assembly is disposed in the flow-guiding path to filter and clean the air pollution source in the air guided by the blower. The gas detection module is disposed in the flow-guiding path of the main body to detect the air pollution source and transmit a gas detection data.

Methods, apparatuses, and systems for monitoring gas leaks are disclosed herein. An example Heating Ventilation and Air Conditioning (HVAC) may comprise: a sampling tube fluidly coupled to a first opening defined in a conduit; and a sensor assembly fluidly coupled to the sampling tube. The sampling tube is positioned exterior to the conduit and extending along a direction of a gravitation force. The sensor assembly is configured to receive one or more gases that have a greater density in comparison to the ambient air and sense the one or more gases to generate a signal.

A method for the removal of mycotoxins from a space associated with a built environment is disclosed. The method may include one or more of the steps of: filtering air within the space using a first filter including a High-Efficiency Particulate Air (HEPA) filter and a second filter including a carbon filter; and, applying a cleaning product including a high alkaline product to one or more surfaces proximate the space.

An air purifier for use in a vehicle having louvered air vents includes a housing having rear and front air flow openings that are aligned with and in air flow communication with each other. A louver clip is attached to the housing adjacent the rear air flow opening. The louver clip is configured to engage a louver on an air vent in the vehicle to hold the housing in place in front of the air vent. The air purifier includes an annular ultraviolet light bulb having a central air flow opening aligned with the front and rear air flow openings in the housing. An annular ultraviolet reflector at least partially encircles the annular ultraviolet light bulb. The air purifier includes a power source for providing electrical power to the ultraviolet light bulb, and a power switch for turning power on or off to the ultraviolet light bulb.
