DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0026] Before the present invention is described in further detail, it is to be understood that the invention is not limited to the particular embodiments described, as such may, of course, vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to be limiting, since the scope of the present invention will be limited only by the appended claims.

[0027] Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit unless the context clearly dictates otherwise, between the upper and lower limit of that range and any other stated or intervening value in that stated range is encompassed within the invention. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges is also encompassed within the invention, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the invention.

[0028] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Although any methods and materials similar or equivalent to those described herein can also be used in the practice or testing of the present invention, a limited number of the exemplary methods and materials are described herein.

[0029] It must be noted that as used herein and in the appended claims, the singular forms a, an, and the include plural referents unless the context clearly dictates otherwise.

[0030] All publications mentioned herein are incorporated herein by reference to disclose and describe the methods and/or materials in connection with which the publications are cited. The publications discussed herein are provided solely for their disclosure prior to the filing date of the present application. Nothing herein is to be construed as an admission that the present invention is not entitled to antedate such publication by virtue of prior invention. Further, the dates of publication provided may be different from the actual publication dates, which may need to be independently confirmed.

[0031] The invention is described in detail with respect to preferred embodiments, and it will now be apparent from the foregoing to those skilled in the art that changes and modifications may be made without departing from the invention in its broader aspects, and the invention, therefore, as defined in the claims, is intended to cover all such changes and modifications that fall within the true spirit of the invention.

[0032] Referring to FIG. 1, the proposed electrostatic air filter 101 is schematically shown. It contains a case 102 with the ionizer 103 located in the door and the collecting assembly 106 located behind the door. The emitting wires 105 and the exciting mesh-like electrodes 104 constitute an ionizer 103. The ionizer 103 is secured in the inlet door. The exciting electrode 104 is inserted via a slot 108. The exciting electrode 104 (which is preferably earth grounded) may be easily removed through the slot 108 for periodic cleaning. The handle 107 is located on the top of the electrostatic air filter 101. Inside of the handle 107 HVPS and controller electronics are located. HV cables (not shown) are located in a proximity of the electrodes. Due to close proximity the HV cables are short and, in some cases may be replaced with low voltage cables or even bare wires since they do not cross path with low voltage cables.

[0033] FIG. 2 shows the same electrostatic air filter 201 with the ionizing assembly 203 open (as an inlet door). The exciting mesh-like electrode 204 is also exposed. The exciting electrode 204 may be located at the upwind or on the downwind side of the ion emitting wires 205 or on both sides of it. The collecting electrodes 206 are also expose here. The front brackets 209 on which the collecting electrodes are secured are also shown here.

[0034] FIG. 3 shows the same electrostatic air filter 301 with the door open and the collecting electrodes pre-assembly 310 removed. The pre-assembly may be rearranged in the way that the collecting electrodes are inverted. After the inversion the collecting electrode] plate's front edge will be placed at the back. The front edges of the collecting electrodes are usually dirtier than tail edges. Therefore, relatively clean tail edges being placed in front may be used for a long time. That increases the electrodes time between replacement and decreases overall operating expenses.

[0035] FIG. 4 shows the same electrostatic air filter 401 in exploded view. It contains the ionizer 403. The collecting electrodes pre-assembly consists of the collecting electrodes 406, the front brackets 409 with the rail 411. When the collecting electrodes pre-assembly is inserted into the case, the rails 411 are sliding along the slots 412. When the collecting electrodes pre-assembly is fully inserted the collecting electrodes tails are supported and secured by the back bracket 414. The repelling electrodes are secured on the horizontal walls of the case (top and bottom). The electrostatic air filter 401 also contains the top lid 407 with electronics hidden inside and the fans 413 at the air outlet.

[0036] Thus, the specific systems and methods for the electrostatic air filter have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the disclosure. Moreover, in interpreting the disclosure, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms contains and containing should be interpreted as referring to members, or components in a non-exclusive manner, indicating that the referenced elements and components, may be present, or utilized, or combined with other members and components that are not expressly referenced.
