A portable air filtration apparatus capable of rapid and efficient room air turnover and recirculation of filtered and decontaminated air with eradication of both microorganisms and biological agents. The invention relates to a compact device that can be used in ultra-clean air purification using a multi stage electrostatic precipitation and air filtration with disinfection and eradication of both microorganisms and biological agents by the application of ultraviolet light radiation. It can be used in any application where space, lower cost or ultra-fine particulate filtering is needed; such as in clean rooms and surgical suites. The device is extremely efficient for purifying contaminated air from entrained dust and organic substances without using chemicals and physical filters, and it is hygienic and fireproof. The device including its multi stage electrostatic precipitator with the filter, connecting, releasing tubes and the fan is easy to clean and can be portable.

An exhaust fan for preventing air pollution includes a main body and at least one gas detection module. The main body is configured to form an airflow-guiding path and includes a gas guider and a filtration and purification component disposed in the airflow-guiding path. The gas guider introduces an air convection for guiding an air pollution source contained in an air to pass through the filtration and purification component so as to filter and purify the air pollution source. The at least one gas detection module is disposed in the airflow-guiding path for detecting the air pollution source and transmitting gas detection data.

An anti-microbial metal coating may be applied to filter membranes for use in actively depressing microbial viability in filtration applications. The anti-microbial metal coating may be applied to substrates that are considered to be sensitive to damage by conventional metal coating techniques or resistant to metal bonding. The coating may be applied from a salt absorbed to the substrate in solution, converted to a reducible form with a conversion agent, and reduced to active metal format through a low temperature plasma treatment.
