This invention discloses a method for preparing an antibacterial and dust-removal membrane. The method comprises the following steps: depositing a layer of nano-ZnO on the immersed membrane surface as the seed crystal with the atomic layer deposition instrument (ALD instrument); vertically immersing the membrane covered with nano-ZnO layer in a hydrothermal reactor filled with crystal growth solution, heating it for a period of time, taking the membrane out and cooling it to the room temperate, and removing it from the substrate; finally, heating this membrane in a drier, and purging it with nitrogen to remove the paraffin within the membrane pore to obtain the porous membrane with nano-ZnO arrays growing on the surface.

A process is provided for removing viruses and micro-organisms from building air by inactivation of those biological elements within an HVAC filter having exuding halogenated material therein. The filter for the HVAC systems has the exuded halogenated material applied with a tackified material via a sequential spraying operation prior to heat curing either of those materials. The filter can subsequently be formed with other laminated materials for increased efficiency, and pleated for use in the HVAC system. Both porous and non-porous substrate fibers can serve as the substrate web for the exuded halogenated material, preferably processed as a non-woven web during air filter fabrication

A cylindrical structure including a first cloth including a piezoelectric thread that generates an electric potential from external energy, a second cloth including a piezoelectric thread that generates an electric potential from external energy, and a connection portion connecting the first cloth and the second cloth, wherein the first cloth and the second cloth forms a side face of the cylindrical structure.

An infectious agent attenuating or inactivating personal protective equipment device, such as a surgical mask, multilayer mask or respirator having at least one porous filtering layer impregnated with an infectious agent attenuating or inactivating solution that tries to leave behind an infectious agent attenuating or inactivating attenuator composed of an organic acid that preferably is a citric acid, a humectant that preferably is a gelling humectant that preferably is sorbitol which produces or forms a self activating or self replenishing infectious agent attenuator gel and infectious agent attenuating and inactivating air treatment media having a pH of no greater than 5, preferably no greater than 4 and more preferably no greater than 3.5 which is kept moist and activated at or below the desired pH by moisture in the breath of a person wearing the mask. The solution can include a surfactant, such as preferably a rhamnolipid biosurfactant that reduces surface tension both during impregnation of the solution thereby more uniformly impregnating the solution into the at least one porous filtering layer producing an air treatment media having infectious agent attenuating gel more uniformly distributed throughout. The surfactant remains in the gel and reduces surface tension of aerosols and droplets containing viruses and bacteria entrained in the air flowing through the air treatment media contacting the infectious agent attenuating gel more rapidly and efficiently attenuating or inactivating the viruses and bacteria preferably also destroying them by lysing them.
