Abstract
Presented is an air cleaning system, comprising: an electrostatic precipitation air filter comprising a collector electrode, a repeller electrode and a corona wire; a detection system for detecting particles; characterized in that: the detection system is configured to determine a status of the electrostatic precipitation filter from an amount of particles present on the collector electrode. Further presented are methods for determining a status of an electrostatic precipitation air filter and methods for determining a particle size distribution in air.

An air cleaning system, comprising:
- an electrostatic precipitation air filter comprising a collector electrode, a repeller electrode and a corona wire;
- and
- a detection system for detecting particles;
- wherein the detection system is configured to determine a status of the electrostatic precipitation filter from an amount of particles present on the collector electrode;
- and wherein the detection system comprises:
- an actuating component configured for actuating the collector electrode such that present particles on the collector electrode are detached from the collector electrode when activated;
- a detector configured to determine the amount of particles present on the collector electrode from detached collector electrode particles in air.
A particle detector, comprising:
- at least one collector electrode, at least one repeller electrode and at least one corona wire;
- and
- a detection system comprising:
- an actuating component configured for actuating the collector electrode such that present particles on the collector electrode are detached from the collector electrode when the actuating component is activated;
- and
- a detector configured to determine the type of particles present on the collector electrode from detached collector electrode particles in air.
A method for determining a status of an electrostatic precipitation air filter comprising a collector electrode, a repeller electrode and a corona wire, the method comprising:
- determining the status of the precipitation air filter by:
- determining an amount of gathered particles on the collector electrode;
- and
- determining the status of the electrostatic precipitation air filter based on the determined amount of gathered particles;
- and
- wherein determining the amount of gathered particles present on the collector electrode comprises:
- detaching the gathered particles from the collector electrode thereby forming an airborne particle cloud, and
- determining the amount of particles in the particle cloud.
