The present invention provides methods and systems for an ion generation device that includes an elongate housing having a back portion and a pair of side portions extending from the back portion and forming a cavity therein. A conductive portion is disposed within the cavity and connected to a power supply for providing power to the conductive portion. A plurality of tines are engaged to the conductive portion.

The personal rechargeable portable ionic air purifier of the present invention controllably provides ions to energize personal airspaces and to clean personal airspaces such as that of a taxicab or airplane cabin or other environ of viruses, bacteria, pollen, smoke, mold, dust mites, and other particulate pollutants while posing little or no personal shock risk to average users or others in the environ or to others such as to users of pacemakers concerned with the currents produced by air purifiers, provides intuitive and informative operational modes, provides for replacement or interchange of worn or defective ion emitter heads in a manner that secures the emitter head against unintended dislodgement while allowing ease of attachment or interchange when worn out or defective, exhibits a long battery life and among other advantageous aspects is manufacturable at comparatively low cost.

In an air conditioner, an upper heat exchanger and a lower heat exchanger exchange heat between air and a refrigerant. An air cleaner includes a charging unit for charging particles in the air and a dust collecting unit for collecting the particles charged by the charging unit by an electrostatic force. An indoor unit body houses the upper heat exchanger and the lower heat exchanger and houses the air cleaner of which the center position in the height direction is positioned lower than a connection part between the upper heat exchanger and the lower heat exchanger.

A method for removing noxious, hazardous, toxic, mutagenic, and/or carcinogenic compounds and/or precursor compounds from a comingled gas, liquid, and/or solid stream is described. In one embodiment, the method is used to prepare the stream for feeding to an oxidizer, such as a thermal oxidizer, to reduce the amount of particulate matter discharged by the oxidizer and includes passing the stream through an ambient or chilled temperature condenser followed by an optional gas/solid separator, and one or more gas scrubbers prior to feeding to the oxidizer.
