ELECTROSTATIC AIR FILTER DESIGN AND ASSEMBLY

1 . An electrostatic air filter comprising:

a case having an inlet part and an outlet part;

an ionizer located in the inlet part of said case;

a collector located in the outlet part of said case; and

wherein said inlet part of said case is detachable from said outlet part of said case.

2 . The electrostatic air filter according to claim 1 , wherein said case comprises a housing section and a door attached to said inlet part is mounted on said door.

3 . The electrostatic air filter according to claim 1 , wherein said ionizer further comprises an ion emitter and an exciting electrode.

4 . The electrostatic air filter according to claim 3 , wherein said ion emitter comprises a set of thin wires suspended on a frame;

said exciting electrode further comprises an electrically conductive mesh;

wherein said frame and said mesh are suspended at one or more exciting electrode mounting points to the inlet part walls;

wherein said frame is mounted at one or more mesh mounting points at the inlet part walls;

wherein said exciting electrode mounting points and said mesh mounting points and said exciting electrode mounting points are spaced from each other a substantially maximized surface distance from said conductive mesh suspending points.

5 . The electrostatic air filter according to claim 1 , wherein said collector further comprises collecting electrodes and plate-like repelling electrodes essentially parallel to each other and also to the principal direction of the air flow.

6 . The electrostatic air filter according to claim 5 , further comprising a removable substrate and wherein said collecting electrodes are attached to said removable substrate.

7 . The electrostatic air filter according to claim 6 , wherein said removable substrate further comprises one or more brackets supporting said collecting electrodes from an inlet side.

8 . The electrostatic air filter according to claim 7 , wherein said brackets are supported by a rail located at the substantially maximum surface path from the repelling electrodes attachment points.

9 . The electrostatic air filter according to claim 5 , wherein said collecting electrodes further comprises plate-like flat members containing inner flexible electrically conductive part and outer nonconductive parts consisting of porous open cell media.
