An airborne pathogen extraction system that provides for continuous airborne pathogen particle extraction from a specifically targeted area in a room or a specifically targeted area proximate to a user. The pathogenic particles are filtered and/or disinfected before the air is returned proximate to the originating location, or are directed an area away from the user(s). The airborne pathogen extraction systems and methods lower the chances of contagion or infection from airborne pathogens, such as viruses.

A combination of nanoparticles applied onto a mask filtration system, exemplarily including 1%-10% graphene; 1%-10% titanium dioxide; 1%-10% zinc oxide; 1%-10% copper oxide; 1%-10% silicon dioxide; and balance solvent is provided.

The following disclosure relates to an electrification device and an electrical dust collecting apparatus including the same capable of adsorbing and filtering fine dust included in air in an air conditioning apparatus such as an air conditioner or an air cleaner, and more particularly, to an electrification device and an electrical dust collecting apparatus including the same capable of having uniform electrification by fixing an electrification plate and a wire at accurate positions using a fixing member coupled to a case to support both end portions of the electrification plate and the wire.

A docking station for a robotic vacuum cleaner has a pneumatic transfer mechanism that is used to direct air to the robotic vacuum cleaner to thereby transfer dirt from the robotic vacuum cleaner to a docking station.

A filter medium (10) for filtering a fluid, in particular for use in an interior air filter (32), comprises a spun-bonded nonwoven formed at least in part of multi-component segmented pie fibers (1) having at least a first plastic component (2) and a second plastic component (3). The multi-component fibers (1) are largely non-split and in order to manufacture same, segmented pie filaments are spun in a spun-bonding process (S4) to form a spun-bonded nonwoven (10). The segmented pie filaments then form the multi-component fibers (4), the first plastic component (2) and/or the second plastic component (3) being made in particular of a polypropylene.

Provided is a particle capturing system and a particle capturing system capable of capturing even small particles to be captured in a gas phase.

The particle capturing system according to the present technology includes: an acoustic aggregation device that aggregates particles to be captured in a gas phase by applying sound waves to the particles to be captured; and an aggregate capturing device that charges particle aggregates obtained by aggregating the particles to be captured in the gas phase and captures the particle aggregates with an electrostatic force.

An electrostatic filter unit for an air cleaning device includes an ionization unit for charging a particle contained in an air flow, a separation unit arranged downstream of the ionization unit in a direction of flow of the air, with the separation unit including at least two collecting electrodes which are air-permeable, and a protection element for at least one element of the ionization unit.

A composite media alternative to high pressure drop glass microfiber HEPA media for use in applications where HEPA efficiency with an oily aerosol challenge with low resistance are required. The composite media contains two light filtration layers, one or both of which is charged, and the efficiency of the material can be greatly increased over a single layer containing the same weight of material. The composite media contains a backer layer to provide mechanical support to the filtration layers.

A system and method for maintaining, monitoring and improving air quality and purity in a room or environment, such as a hospital room or operating room.

A ventilation type air cleaner includes a housing having a central rotating shaft including a purification part, a washing part, and a sterilization part in a circumferential direction with respect to the central rotating shaft, a rotating unit installed to be rotatable about the central rotating shaft as a rotation center in the housing, a filter assembly detachably coupled to the rotating unit and configured to sequentially pass through the purification part, the washing part, and the sterilization part according to rotation of the rotating unit, an intake duct connected to the housing and configured to guide a flow of air introduced to the purification part, and an exhaust duct connected to the housing and configured to guide a flow of air discharged from the purification part.
