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