Maintenance
Cleaning the Duster Unit
- Ensure the duster is unplugged before cleaning.
- Wipe the exterior of the duster with a soft, damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Periodically check the air intake and output ports for any obstructions and clear them if necessary.

- Remove Filter: Unplug the duster. Carefully remove the foam filter from the intake opening.
- Wash: Rinse the filter under cool running water until all visible dust and debris are removed. You may use a mild soap if necessary, but rinse thoroughly to remove all soap residue.
- Dry: Squeeze out excess water. Allow the filter to air dry completely before re-installing it into the duster. Do not use heat to dry the filter, as this may damage the material.
- Re-install: Once completely dry, place the clean filter back into the duster's intake opening.
Regular cleaning of the filters ensures optimal performance and extends the life of your duster.
