Operating
Once the new filters are installed, reassemble your vacuum cleaner according to its specific instructions. The filters will now work to capture dust and allergens, ensuring clean exhaust air during operation. Monitor your vacuum's suction power and the cleanliness of the filters regularly.
Maintenance
To maintain optimal performance and extend the life of your Nispira filters, regular cleaning is recommended.
- Cleaning Frequency: It is recommended to rinse the foam and felt filters every 3 months, or more frequently depending on usage.
- Washing Instructions: Rinse the filters under running water until the water runs clear. Gently squeeze out excess water. Do not wring.
- Drying: Allow the filters to air dry completely for at least 24 hours before reinstalling them into your vacuum. Do not use a clothes dryer or other heating devices, as this can damage the filter material.
- Replacement: Replace the foam and felt filters every 12 months, or as needed, to maintain peak vacuum performance and filtration efficiency.
Troubleshooting
- Reduced Suction: If you experience reduced suction after installing new filters, ensure all filters are correctly seated and the vacuum is fully reassembled. Check for any blockages in the hose or brush roll. If the issue persists, the filters may be clogged and require cleaning or replacement.
- Unusual Odor: An unusual odor during vacuum operation can indicate that the filters need cleaning or replacement. Ensure filters are completely dry before reinstallation to prevent mildew.
