Disclosed is an air conditioner for creating a comfortable indoor environment. The air conditioner includes an indoor unit configured to have a carbon dioxide remover for filtering carbon dioxide from indoor air to supply clean air into a room, and discharging the filtered carbon dioxide to the outside, an outdoor unit configured to have an oxygen generator for separating oxygen from outdoor air introduced from the outside to supply the separated oxygen into the room, and discharging residues from which the oxygen is separated to the outside; and a processor configured to control the carbon dioxide remover and the oxygen generator to discharge the filtered carbon dioxide and the residues to the outdoor together. According to the disclosure, by first removing the carbon dioxide from the room and then discharging the carbon dioxide and the residues while operating the oxygen generator, a piping installation operation by a simple piping structure as well as an efficient operation is possible.

The present invention relates to a toxic gas purification apparatus having a local exhaust function. Here, the purification device is a device for collecting and purifying toxic or harmful gases in places such as a laboratory or a workplace that are easily exposed to various chemical substances. In addition, the purification device includes a local exhaust means for intensively inhaling harmful gas generated at a specific point of interest by the user. Accordingly, the purification device includes an additional function capable of intensively collecting and purifying harmful gases at specific points in addition to the original function of collecting and purifying harmful gases in a wide area.

Implementations are directed to a smart filter apparatus including an air filter, a sensor supported by the air filter and sensitive to a pathogen, and a control unit in data communication with the sensor and operable to perform operations including receiving, from the sensor, an indication of the pathogen present in air incident on the sensor, generating, by the control unit, a pathogen alert response, and providing, by the control unit, the pathogen alert response.

The present invention relates to an improved device for supplying temperature controlled laminar air flow (TLA) of filtered air to generate a clean air zone, e.g. a controlled personal breathing zone, at a point of care. The specific relative placement of the air inlets and outlets of the device of the present invention enables the provision of a more stable TLA based clean air zone than the prior art devices and at the same time allows for extensive monitoring and reporting features.

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.
