Abstract

An air purifier (10) is provided having a housing (11) having a grilled air inlet (12), a grilled air outlet (13), and a control panel (14). The air purifier (10) also includes a pre-filter (16), a main filter (17), a blower (18) and a controller (19), all mounted within the housing (11). The controller (19) has a central processing unit having a permanent memory for storing the program instructions for operation and control of the air purifier, a working memory, and a non-volatile memory for the permanent storage of programs and counters. The controller is programmable so as to control the operation of the blower according to time and speed parameters entered into memory.
