Fine dust appears on the exhaust side or around the HEPA filter cover.

Safety first: Remove the battery before handling filters.

• Remove and inspect HEPA: Take out the HEPA filter and check for tears, holes, or deformation.
• Check orientation: Reinstall the filter in the correct direction as indicated by arrows or markings.
• Inspect seals: Ensure any foam or rubber seals around the HEPA are intact and seated properly.
• Replace if damaged: Install a new Insignia HEPA filter if there is any damage or persistent dust leakage.
