Disclosed in an air purification device comprising a case that contains at least a first filtering system including an M6 filter according to standard EN1822, a second filtering system including UV-C lamps, and a third filtering system. The second filtering system is situated between the first filtering system and the third filtering system, the UV-C light of the lamps sterilising the air flow that passes through the second filtering system. The UV-C light of the lamps has a powerful destructive effect on the DNA chains of microorganisms or cells retained in the first filtering system and the third filtering system and also on those of microorganisms or cells in the space delimited between the first filtering system and the third filtering system.

Disclosed herein are base metal catalyst devices for removing ozone, volatile organic compounds, and other pollutants from an air flow stream. A catalyst device includes a housing, a solid substrate disposed within the housing, and a catalyst layer disposed on the substrate. The catalyst layer includes a first base metal catalyst at a first mass percent, a second base metal catalyst at a second mass percent, and a support material impregnated with at least one of the first base metal catalyst or the second base metal catalyst. The preferred catalyst composition is a combination of manganese oxide and copper oxide.

The disclosure relates to an apparatus for reducing the quantity of solid particles in ambient air. A predefined treatment area is delimited at least in part by an enclosure. The enclosure is at least partially non-physical and formed by at least one air curtain that can be produced by an air flow generating device. At least one air filter device, which is connected in terms of flow to the ambient air of the treatment area is designed to filter solid particles directly out of the ambient air of the treatment area.

The present disclosure relates to air filters. More particularly, it relates to air filters including pleated filter media that can be uniformly expanded and contracted. In some embodiments, the air filters are adjustably sized air filter systems. In some embodiments, the air filters can be used in a window opening.

The present disclosure relates to a tower type air purifier installed and operated outdoors to purify air pollutants such as fine dust. More particularly, the tower type air purifier is manufactured by modularizing and combining main constituent components of a main body in a tower form in order to easily separate and purify air pollutants in the air. A controller, which prepares an air purification algorithm based on air pollution measurement information, controls a blower, a mist sprayer, an ion emitter, a cleaning water injector and an adsorption brush installed in the purifier to quickly purify a large amount of suctioned air. The purifier can be operated independently or a group of purifiers can be operated through remote control according to an air purification algorithm suitable for each air pollution region and provided from a weather center.

The present invention relates to an air decontamination process system, which comprises one or more depollution towers (T), wherein each tower (T) comprises one or more air inlets, with or without air filtration (2), containing such an air decontamination zone, suitable devices for this purpose, an external tower (3) or air tank, where the air is already decontaminated and treated, and an outlet of decontaminated air at the top of the tower (4).

The air thus decontaminated may be released into the atmosphere, the process of the invention being able to give quantities of unpolluted air of the order of 400,000 m3 to 600,000 m.sup.3 per tower (T) per hour.

In this way, the present invention is part of the technical field of the new technologies for the treatment of environmental components, in this specific case, for the treatment and improvement of large volumes ambient air quality.

Provided is a tower-type outdoor air cleaning apparatus that is disposed outside a facility that performs air cleaning, cleans outside air, and supplies the cleaned air, including: a tower body unit that is disposed away from the facility on one side of the facility, is provided in a tower type with a double-wall structure, in which fomentation is performed inward, air is filtered and suctioned, and is exhausted; an air supply unit that is provided above the tower body unit, in which air is supplied through an upper portion thereof and air flows in through a side portion at a plurality of locations of an outer circumference thereof and is mixed with the air supplied through the upper portion; an air ventilation filter unit that is disposed inside the air supply unit and the tower body unit, filters the mixed air supplied from the air supply unit to be supplied to the facility connected thereto, and exhausts the air circulated in the facility to the outside; a fomentation facility unit that is disposed inside the tower body unit and generates heat and electricity using solar energy for use in fomentation; and a control unit that is connected to the air ventilation filter unit and the fomentation facility unit to control the amount of air supplied by the air supply unit through the air ventilation filter unit, and controls production and transfer of heat and electricity using solar energy in the fomentation facility unit.

A system and method for generating air quality scores for air quality within certain locations are presented. The method includes identifying at least one air pollution source within the predetermined perimeter around the at least one location; extracting an air quality score range based on the at least one location from at least one data source; identifying at least one environmental variable based on the at least one location and the at least one time parameter; simulating at least one air pollution measurement based on the at least one environmental variable and the at least one air pollution source; and generating at least one air quality score respective of the air quality score range, wherein the at least one air quality score is based on the at least one air pollution measurement.
