Metal mesh are attached to  filter media tightly, which enhances the strength of the pleated filter media, and also  effectively weaken the shaking of the filter material to avoid second time pollution Metal mesh pre-filter are used as primary filters in air-conditioning system, mainly used to filtrate particles bigger than 5  micrometers.
