Abstract

A stackable air treatment device is provided and includes a base, a cover, a plurality of air treatment modules modularly stackable between the base and the cover in groups of one or more to form a stack with the base and the cover and a blower configured to move air from an exterior of the stack into the stack and out through the cover. Each air treatment module in the stack is configured to purify, clean, and/or condition the air moved by the blower.

Claims (21)

1 . A stackable air treatment device, comprising:

a base;

a cover; and

a set of air treatment modules that are respectively interchangeable with one another to be modularly stackable between the base and the cover in groups of one or more to form a stack with the base and the cover,

the base, the cover and each air treatment module in the stack having a same peripheral shape and size for fitting together in the stack and each air treatment module in the stack comprising:

filter media; and

a blower configured to move air from an exterior of the stack through the filter media and subsequently to and through the cover.

2 . The stackable air treatment device according to claim 1 , wherein the base, the cover, and each of the air treatment modules comprises a stacking element for engagement with a corresponding stacking element of a neighbor in the stack and a stacking direction of the stack is vertical or horizontal.

3 . The stackable air treatment device according to claim 1 , wherein a portion of the air treatment modules have differing capacities.

4 . The stackable air treatment device according to claim 1 , wherein at least two air treatment modules are stackable between the base and the cover and are operable in series or in parallel.

5 . The stackable air treatment device according to claim 1 , wherein the cover is formed to define an aperture and comprises filter media in the aperture.

6 . The stackable air treatment device according to claim 1 , wherein:

the base and the air treatment modules each comprise an inter-module power connector, and

the stackable air treatment device further comprises a power distribution system configured to distribute power from the base to each air treatment module in the stack via the inter-module power connectors.

7 . The stackable air treatment device according to claim 1 , wherein, for each air treatment module:

the filter media is cylindrical, and

the blower is disposed within the filter media and configured to draw the air through the filter media in 360° directions and subsequently to blow the air longitudinally.

8 . The stackable air treatment device according to claim 1 , further comprising at least one of:

an air quality monitor operably disposed to sense a quality of the air moved by the blower; and

a control panel operably disposed on one of the cover and the base, the control panel being disposed and configured to control operations of the air treatment modules in the stack.

9 . The stackable air treatment device according to claim 1 , wherein at least one of the air treatment modules in the stack is provided as multiple air treatment modules in parallel.
