Abstract
An electrostatic room air cleaner includes a housing having a given profile and a plurality of electrostatic precipitation collector units arrayed in the housing with a common fan to circulate room air through the plurality of electrostatic precipitation collector units simultaneously. A total clean air delivery rate is delivered that is determined as the arithmetic sum of the clean air delivery rates of the plurality of electrostatic precipitation collector units arrayed in the housing of given profile. The greater the number of units arrayed, the smaller may be their size, and the easier they are to handle, maintain and replace.
