- Ensure the dust cup is securely attached and the filter is properly seated before operating the vacuum.
- Regularly check the filter for visible dirt and debris to determine when cleaning is necessary.

4. Cleaning and Maintenance
The Greenote GF50 HEPA filter is washable and reusable, extending its lifespan and maintaining filtration efficiency. Follow these steps for proper cleaning:
- Remove Filter: Detach the dust cup and carefully remove the dirty HEPA filter.
- Wash Filter: Rinse the HEPA filter under cool, running water until the water runs clear. Gently tap the filter to dislodge stubborn dirt. Do not use detergents or hot water, as this may damage the filter material.
- Dry Completely: Allow the filter to air dry completely for at least 24 hours before reinstallation. Ensure it is thoroughly dry to prevent mold growth and damage to the vacuum motor. Do not use heat sources like hair dryers or direct sunlight for drying.
- Reassemble: Once completely dry, reassemble the filter components and place them back into the dust cup. Reattach the dust cup to the vacuum cleaner.
