Installation
Follow these steps to replace the filters in your Shark Rocket Powerhead vacuum cleaner:
- Locate Filter Compartments: The pre-motor filters (foam and felt) are typically located under the dust cup, while the post-motor filter is usually at the rear of the vacuum.
- Remove Old Filters: Open the filter compartments and carefully remove the used foam, felt, and post-motor filters. Discard them appropriately.
- Insert New Pre-Motor Filters: Place the new foam filter into its designated slot, followed by the felt filter on top of it. Ensure they are seated correctly.
- Insert New Post-Motor Filter: Place the new post-motor filter into its compartment at the rear of the vacuum.
- Close Compartments: Securely close all filter compartments.

Operating Your Vacuum with New Filters
After installing the new Leadaybetter filters, your Shark Rocket Powerhead vacuum cleaner is ready for use. The H12 filtration effect of these filters helps to efficiently capture particles as fine as 0.3 microns, improving air quality during operation. Ensure all compartments are securely closed before powering on the vacuum.
Maintenance and Cleaning
To maintain optimal performance and extend the lifespan of your filters, follow these cleaning guidelines:
- Regular Cleaning: It is recommended to clean the filters every 2-3 weeks, depending on usage.
- Washing: Rinse the foam and felt filters with clean water until the water runs clear. You may use a mild soap if necessary, but ensure all soap residue is thoroughly rinsed.
- Drying: Allow the filters to air dry completely for at least 24 hours before re-installing them into the vacuum. Do not use a dryer or direct heat, as this can damage the filter material.
- Replacement: Replace the filters every 2-3 months to ensure efficient filtration and prevent reduced suction.

Troubleshooting
- Reduced Suction: If you experience reduced suction, check if the filters are dirty or clogged. Clean or replace them as recommended. Ensure all filter compartments are sealed properly.
- Unusual Odors: Persistent odors may indicate a need for filter cleaning or replacement. Ensure filters are completely dry before re-installation to prevent mildew.
- Filters Not Fitting: Double-check that you have the correct filter models for your specific Shark Rocket Powerhead vacuum (AH400, AH400C, AH401, AH452, AH452W, AH454Q). Refer to the specifications section.
