• The pre-filter can be gently vacuumed using hand tool attachments (no rotating brushes).
• Do not use any solutions, brushes or sharp objects to clean the pre-filter, as this can damage the filter.
HEPA / Activated Carbon Filter Maintenance

• A vacuum cleaner may be used to gently clean the HEPA filter periodically.
