         8 . The cleaning device of  claim 1 , wherein the ozone generator include a first electrode and a second electrode positioned beneath and spaced from the first electrode such that a gap is positioned therebetween. 
     
     
         9 . The cleaning device of  claim 1 , wherein the ozone generator is spaced from the catalyst such that an air gap is positioned therebetween. 
     
     
         10 . The cleaning device of  claim 1 , further comprising a ultraviolet light positioned between the ozone generator and the catalyst. 
     
     
         11 . The cleaning device of  claim 1 , wherein the air driver includes at least one of a fan or an ion generator. 
     
     
         12 . The cleaning device of  claim 1 , wherein the first width is at most about 2.35 inches, the second width is at most about 5.4 inches, and an overall length of the housing is at most about 9 inches, and wherein the air driver is configured to drive air through the housing at a rate between 300 and 500 cubic feet per minute. 
     
     
         13 . The cleaning device of  claim 1 , further comprising a first screen extending across the inlet and a second screen extending across the outlet. 
     
     
         14 . The cleaning device of  claim 1 , wherein the catalyst is a first catalyst, further comprising:
 a first screen positioned upstream of the first catalyst, wherein the first screen is coated in a catalyst material such that the first screen comprises a second catalyst; and   a second screen positioned downstream of the first catalyst such that the first catalyst is positioned between the first screen and the second screen.   
     
     
         15 . The cleaning device of  claim 1 , further comprising a filter positioned within the first chamber, wherein the first portion of the housing defines a filter aperture and includes a cap positioned to selectively enclose the filter aperture, the cap selectively removable to facilitate removing the filter from the first chamber through the filter aperture. 
     
     
         16 . A cleaning system comprising:
 an ozone generator;   an air driver;   a catalyst; and   a controller configured to control the ozone generator and the air driver to emit ozone into a space to neutralize contaminates within the space and then, after a predetermined amount of time, cycle air in the space through the catalyst to neutralize the ozone in the air.
