Abstract
An ionization device may be configured to be portable, and to rest on a surface such as a floor or desk top. The ionization device includes an air-intake port, an ion generator, an ozone catalyst for removing at least some ozone from air, and an air discharge. Air enters the device through the air-intake port, and at least some of the air is ionized to remove particulates. The air is then moved past or through the ozone catalyst to remove at least some of the ozone from the air. A controller may be used to monitor particulates, temperature, humidity, and/or other relevant factors and/or to adjust the ionization level.
