Air purifier

Abstract

An air purifier is disclosed having an electrostatic chamber and a germicidal chamber, wherein the two chambers are distinct and there is no air flow communication between the electrostatic and germicidal chambers.

1 . An air purifier, comprising:
 an electrostatic chamber;   a germicidal chamber;   wherein there is no air flow communication between the electrostatic and germicidal chambers.   
     
     
         2 . The air purifier of  claim 1 , wherein:
 the electrostatic chamber comprises a first electrode array, a second electrode array and a first air stream moving in a direction from the first electrode array toward the second electrode array; and   the germicidal chamber comprising a germicidal lamp and a second air stream.   
     
     
         3 . The air purifier of  claim 2  wherein the second air stream moves in a substantially vertical direction. 
     
     
         4 . The air purifier of  claim 2  wherein the first air stream moves in a substantially horizontal direction. 
     
     
         5 . The air purifier of  claim 1 , further comprising:
 a housing, having a top, bottom, front and back;   wherein the electrostatic chamber has an electrostatic chamber entrance at the back of the housing and an electrostatic chamber exit at the front of the housing; and   wherein the germicidal chamber has a germicidal chamber entrance near the top of the housing and a germicidal chamber entrance near the bottom of the housing.   
     
     
         6 . The air purifier of  claim 1 , further comprising a fan positioned in the germicidal chamber. 
     
     
         7 . The air purifier of  claim 5  wherein the fan is positioned near the bottom of the housing. 
     
     
         8 . The air purifier of  claim 1  wherein the germicidal chamber is positioned within the electrostatic chamber. 
     
     
         9 . The air purifier of  claim 1  wherein the germicidal chamber and the electrostatic chamber are positioned side-by-side. 
     
     
         10 . An air purifier, comprising:
 an electrostatic chamber comprising a first electrode array, a second electrode array and a first air stream moving in a direction from the first electrode array toward the second electrode array;   a germicidal chamber comprising a germicidal lamp and a second air stream;   wherein there is no air flow communication between the first and second air streams.   
     
     
         11 . The air purifier of  claim 10  wherein the second air stream moves in a substantially vertical direction. 
     
     
         12 . The air purifier of  claim 11  wherein the first air stream moves in a substantially horizontal direction. 
     
     
         13 . The air purifier of  claim 10 , further comprising:
 a housing, having a top, bottom, front and back;   wherein the electrostatic chamber has an electrostatic chamber entrance at the back of the housing and an electrostatic chamber exit at the front of the housing; and   wherein the germicidal chamber has a germicidal chamber entrance near the top of the housing and a germicidal chamber entrance near the bottom of the housing.   
     
     
         14 . The air purifier of  claim 10 , further comprising a fan positioned in the germicidal chamber. 
     
     
         15 . The air purifier of  claim 14  wherein the fan is positioned near the bottom of the housing. 
     
     
         16 . The air purifier of  claim 10  wherein the germicidal chamber is positioned within the electrostatic chamber. 
     
     
         17 . The air purifier of  claim 10  wherein the germicidal chamber and the electrostatic chamber are positioned side-by-side.
