Disclosed is a fine dust collecting device using a human body based electrostatic energy harvesting element. The fine dust collecting filter device includes an electrostatic energy harvesting element for collecting and generating current; a charging filter connected to the electrostatic energy harvesting element such that the charging filter is electrically charged to have a first polarity and thus electrically charges fine dust particles; a collecting filter connected to the electrostatic energy harvesting element such that the collecting filter is electrically charged to have a second polarity opposite to the first polarity; and a rectifier disposed between and connected to the electrostatic energy harvesting element, and the charging filter and the collecting filter.

An electrostatic filter module for an air cleaner includes a housing having an installation space configured to be sealed at least against ingress of liquid.

A personal protective apparatus, having a wearable support member and a mesh shield securable thereto. The mesh shield may include first and second air-permeable conductive layers secured to the wearable support member and a first air-permeable non-conductive layer received between the first and second air-permeable conductive layers to separate them, and a portable power supply coupled to the mesh shield with a negative high voltage lead to the first air-permeable conductive layer and a positive high voltage lead to the second air-permeable conductive layer. The mesh shield may be a flexible mesh shield, and include at least one air-permeable layer secured at a first layer upper end to the wearable support member to hang from the wearable support member, the at least one air-permeable layer including at least one of an anti-virus material and an anti-microbial material. A fibrous filter layer may overlay an outer surface of the mesh shield.

A filter for removing ferrous particles from a fluid. The filter has an outer filter housing and a non-ferrous liner inside the housing. A plurality of magnets are longitudinally extended at intervals outside the liner. An insert inside the liner imparting a directional flow to the fluid inside the filter whereby ferrous particles in the fluid are trapped by the magnets and held against the non-ferrous line.

A macro electrically active mask includes two conductive layers separated by at least one filtering and insulating layer. The conductive layers are connected to each other by a power source. The power source includes an oscillator and a high voltage transformer. The power source generates a periodic voltage with a fundamental frequency and multiple harmonic frequencies. The power source is connected between the two conductive layers and the periodic voltage generates a periodic electric field between the two conductive layers. The fundamental frequency, the duty cycle, and the amplitude of the periodic voltage are configured to inactivate the microorganism that pass through the electric field.
