Abstract:
The invention provides a monitoring device for monitoring an air cleaning system for determining when a particle filter of the air cleaning system needs cleaning or replacement. The monitoring device is a remote unit for application to the air cleaning system when a periodic monitoring function is to be performed. It is used to monitor changes in the sound made by the air cleaning system over time to derive information relating to the filter status.
