Abstract
A filter media includes flat sheets that are corrugated into a honeycomb matrix wherein air flows through the material and airborne contaminants are captured on the sidewalls of the material, wherein an active electrostatic field is applied to the flat sheets.
Claims10
An active field polarized media air cleaner comprising:
- a conductive screen;
- a corrugated sheet, wherein the corrugated sheet comprises alternating flat layers and corrugated layers that define channels therethrough that allow for passage of air, wherein the channels are aligned with a direction of airflow and do not interrupt airflow through the channels, wherein each channel extends from a first side of the corrugated sheet to a second side of the corrugated sheet;
- a high-voltage power supply connected to the conductive screen that applies a voltage to the conductive screen that creates a polarizing field upstream of the corrugated sheet that charges particles passing through the field;
- wherein when the voltage is applied to the conductive screen, the corrugated sheet at a ⅜″ thickness and under a voltage of 7 kv removes at least 34%, 34%, 39%, 39%, 45%, and 67% of particle sizes in microns respectively:
- 0.3, 0.5, 0.7, 1, 2, and 3, as compared to a 0-voltage applied media that removes 20%, 17%, 19%, 23%, 26%, and 42% of particle sizes in the same particle sizes.

An active field polarized media air cleaner comprising:
- a corrugated sheet, wherein the corrugated sheet comprises alternating flat layers and corrugated layers that define channels therethrough that allow for passage of air, wherein the channels are aligned with a direction of airflow for direct airflow therethrough, wherein each channel extends from a first side of the corrugated sheet to a second side of the corrugated sheet;
- a high-voltage power supply connected to a conductive member embedded within the corrugated sheet, wherein the high-voltage power supply applies a voltage to the conductive member that creates a polarizing field within the corrugated sheet that charges particles passing through the field;
- wherein when the voltage is applied to the conductive member, the corrugated sheet at a ⅜″ thickness and under a voltage of 7 kv removes at least 34%, 34%, 39%, 39%, 45%, and 67% of particle sizes in microns respectively:
- 0.3, 0.5, 0.7, 1, 2, and 3, as compared to a 0-voltage applied media that removes 20%, 17%, 19%, 23%, 26%, and 42% of particle sizes in the same particle sizes.
