A method of filtering indoor air pollution for filtering air pollutant in an indoor space is disclosed. A plurality of gas processing devices is provided for detecting and filtering air pollutant, and transmitting device inner gas detection data. A connection device is provided for receiving and transmitting the device inner gas detection data to a cloud processing device. The cloud processing device intelligently compares and selects to drive a closest gas processing device to filter the air pollutant and drive the gas processing devices to determine a convection path and generate at least one airflow . The airflow accelerates the movement of the air pollutant along the convection path to move the air pollutant towards the closest processing device adjacent to the air pollutant for filtering, so that the air pollutant in the indoor space can be filtered rapidly to obtain a clean, safe and breathable air condition.

A method for continuously removing a particular type of gas molecules (“gas molecules”) from a gas stream includes selecting a liquid having an affinity for the gas molecules to be removed, and providing the selected liquid to each of a first and second mat, each mat formed from a plurality of fibers having the ability to retain the selected liquid within longitudinally extending channels having longitudinally extending openings against moving into the space between the individual fibers, the mats in fluid communication therebetween with the selected liquid. The method includes directing the gas stream through a portion of the first mat into contact with the selected liquid along the longitudinally extending openings whereby the selected liquid absorbs the gas molecules, and directing a second gas through a portion of the second mat so that the gas molecules, absorbed by and disbursed throughout the selected liquid, are stripped and carried away.

A system for capturing carbon dioxide from ambient air includes an input port configured to accept ambient air into the system, an air conditioning system configured to draw the ambient air into the input port and reduce a temperature of the ambient air, a filter device configured to capture carbon dioxide from the ambient air after the temperature of the ambient air is reduced by the air conditioning system, and an output port, through which the ambient air is discharged from the system after the ambient air is processed with the filter device.

An air purifying system includes: a carbon dioxide remover including first and second spaces partitioned by a gas permeable membrane with 50 nm or less diameter micropores; a feed passage leading to-be-purified air from a room to the first space; a supply passage supplying clean gas having lower carbon dioxide and higher oxygen concentrations than the to-be-purified air to the second space; a discharge passage discharging, from the second space, mixed gas; a return passage leading purified air from the first space into the room, the purified air resulting from removing carbon dioxide from the to-be-purified air; and adjusting equipment adjusting a gas pressure in the first and second spaces to be substantially equal to each other. The to-be-purified air flows in the first space along a surface of the gas permeable membrane, and the clean gas flows in the second space along a surface of the gas permeable membrane.

This invention relates to a combination of machinery, electronics and building space design using specialized disinfection systems, air filtration, audio-visual communication, electronic controllers and isolation booths in a manner that mitigates the risk of disease transmission among simultaneous and serial users of the shared space.

A surgical treatment system for contaminated air streams having particulate contamination, polar contamination and/or nonpolar contamination in the gas or vapor stream. A surgical smoke plume treatment system and method provide or define a multi-stage treatment process that mechanically filters the air stream, followed by nonpolar decontamination and then polar decontamination or treatment. The system may be used stand alone or incorporated and used with other surgical instruments or incorporated into an air handler adapted to decontaminate an air stream. A desiccant may optionally be used to remove water from the air stream.
