Abstract: An air purifier (10) is disclosed which includes a housing (11) having a top wall with a schedule indicator (14). The housing top wall has a central recess (16), an annular inner groove (18) positioned concentrically about the central well, and an annular outer groove (20) positioned concentrically about the inner groove. An annular plateau (28) is formed between the inner groove and the outer groove. A first reset ring (31) is positioned within the outer groove for rotational movement therein. The first reset ring includes two inwardly extending timing indicating tabs (32) and (33). A second reset ring (35) is positioned within the inner groove for rotational movement therein. The second reset ring includes two outwardly extending timing indicating tabs or indicators (36) and (37). A knob (43) coupled to a power switch (45) is positioned within the central well for rotational movement therein.

Abstract: An air purifier (10) is disclosed including an electrically motorized fan (12). The air purifier includes a manual touch pad controller (16) which allows the manual operation of the air purifier and a computer interface which allows the user to control the fan speed through a personal computer (18). The software can allow the user to utilize the computer to automatically turn the air purifier on or off, change the fan speed, indicate the percentage of filter life remaining, and provide a mode of operation which includes a timer mode, wake mode or snooze mode that is in sync with the computer. In an air purifier wake mode, the air purifier is turned “on” whenever the computer is in an awake mode and turned “off” whenever the computer is in a sleep mode. In an air purifier snooze mode, the air purifier is turned “on” whenever the computer is in a sleep mode and turned “off” when the computer is in an awake mode.

Abstract: A humidifier (10) is disclosed having a top portion (11), a middle portion (12) and a bottom portion (13). The middle portion is essentially a water tank which provides water to be used in humidification. The bottom portion has a floor (41) and side walls (42) extending from the floor to form a tub (43) having a select height (SH1). The bottom portion is configured so that should water be uncontrollably released from the middle portion, the water level within the middle portion (MPEWL) will reach an equilibrium level with the catastrophic water lever (CEWL) within the bottom portion below the selected height of the bottom portion (SH1). When the middle portion water lever (MPEWL) reaches the same height or equilibrium lever with the bottom portion catastrophic water lever (CEWL) the flow of water from the middle portion will cease. As this equilibrium level is below the select height of the bottom portion (SH1) the water will be fully captured and will not overflow onto the underlying floor.
