Claims

1-10. (canceled)

11. An air purifier comprising at least one removable particulate filter, a fan or impeller and a motor for driving said fan or impeller, a top and, opposite thereto, a base and means for elevating said base from the ground, at least one side surface connecting said top and base, a base air intake disposed on said base and facing the ground in a working configuration a top air intake on said top and facing away from the ground in a working configuration and a pair of opposing air outlets, and wherein said top and base are rectangular or square in form and comprises four side surfaces connecting said top and base, and wherein the air outlets are disposed on two opposing side surfaces.

12. The air purifier according to claim 11 wherein the means for elevating said base comprises a leg or stand.

13. The air purifier according to claim 11 further comprising an ioniser.

14. The air purifier according to claim 13 wherein the ioniser is disposed on an exterior surface of said purifier to ionise air outside the purifier.

15. The air purifier according to claim 11 further comprising a supporting plate elevated above said top.

16. The air purifier according to claim 11 wherein the removable particulate filter is a HEPA filter.

17. The air purifier according to claim 11 further comprising a pair of air flow ducts, each air flow duct comprising an air intake, a fan or impeller, a removable particulate filter, and an air outlet.

18. The air purifier according to claim 1 wherein the fan or impeller for each air duct is powered by a single motor.

19. The air purifier according to claim 14 wherein the ioniser on the exterior surface of the purifier facilitates aggregation of domestic dust particles, the air purifier further comprising an interior ioniser to facilitate capture of the aggregated domestic dust particles by the removable particulate filter.

20. The air purifier according to claim 11 wherein the air purifier has a bottom surface and the top and bottom surface have an aperture to intake air when the fan draws air into the air purifier.

Description

[0039] Embodiments of the invention will now be described with reference to the following non-limiting drawings in which:

[0040] FIG. 1 shows a mid-cross section through an air purifier with a side wall (1), a top (2) and a bottom (3) surface. The top (2) and bottom surface (3) have an aperture (4a and 4b) which function as an air intakes when the fan (labelled) draws air from ambient into the device. The aperture air intakes (4a and 4b) are guarded by a poke filter (5a and 5b).

[0041] The device also comprises a pair of replaceable particulate HEPA filters (7a and 7b) through which the air must pass as it is moved by the fan towards the exit apertures (8). These outlets (8) are filled with a further poke guard (9) to prevent the user from easily accessing the interior of the device and causing damage to the device or themselves.

[0042] The interior of the purifier is formed into two distinct air flow chambers (A and B) where are is drawn into the device through air intake (4a) and HEPA filter 7a into chamber A and through air intake (4b) and HEPA filter (7b) into chamber B. The bulkhead (11) separates chambers A and B and also maintains the fan in a central disposition.

[0043] The device is maintained off the ground in use by legs (10).

[0044] FIG. 2 is a schematic and shows how the air is circulated by an embodiment of the invention. The device is maintained off the ground by legs (10). Air is drawn in through the aperture on the base by the fan (not shown) and into the device. It exits through the outlets on the side (8). In this embodiment air is also drawn in through the aperture (18) on the top of the device thus creating an especially contrived air flow between air drawn in through the base (4) and air drawn in through the top.

[0045] FIG. 3 is a perspective view of a device according to the invention. Shown is a purifier on legs (10) to maintain the device away from the ground and permitting air to be drawn from underneath the device during use.

[0046] On the top is an air intake (4a) through which air is drawn by a fan. There is also an intake on the base (3) not shown and which draws air from underneath the device. Side wall (1) has no air outlet whereas side wall (20) does have an air intake (8) and which is protected by a poke guard.

[0047] The device also has a table top (21) which can be used by the consumer to stand domestic decorative or functional items. The stand also agitates the air being drawn into the device thus improving the aggregation of dust particles in the ambient air.

[0048] In FIG. 4 we see the same device but from the front view. Accordingly, the air outlets on side walls (20) are not in view. The base (3) is maintained above the ground by an amount commensurate with optimal agitation of the air stream and thus optimal agitation of dust particles in the ambient air.

[0049] FIG. 5 is a bottom view of the device and which shows the legs (10) and a circular air intake (4b) protected by a pre-filter or poke guard.

[0050] FIG. 6 is a plan view of the same device without the table top item (21) to show the configuration of the air intake on the top (2). The air intake is circular in design to facilitate drawing of air from all directions equally.

[0051] FIG. 7 is a schematic view from the side of a similar embodiment in which can be seen the air outlet (8) and which is rectangular and protected by a poke guard. The air outlet is of a substantially similar shape to the device in side profile.
