How often should I clean the Cooper & Hunter Astoria Series filter?

Cooper & Hunter Multi R Installation Manual does not publish a calendar interval for this line in the sourced maintenance section. It identifies dirty filter maintenance as a condition to address, so treat visible dirt, weak airflow, or reduced cooling/heating as the manual-backed trigger. The source note is: Air purifying filter & Air filter(behind).

Is the Cooper & Hunter Astoria Series filter washable or disposable?

The sourced rows are treated as washable air-filter entries unless the capacity table shows a specific OEM disposable-filter part number for that model.
