Installation Guide
Follow these steps to replace the filters in your Shark IZ300/IZ320 series cordless vacuum cleaner. Always ensure the vacuum is turned off and unplugged before performing any maintenance.
- Locate the Filter Compartment: Refer to your Shark vacuum's user manual to identify the location of the HEPA filter and the foam/felt filter compartments. These are typically found near the dust cup.
- Remove Old Filters: Carefully open the filter compartments and remove the used HEPA filter, foam filter, and felt filter. Dispose of them responsibly.
- Install New HEPA Filter: Insert the new HEPA filter into its designated housing. Ensure it is seated firmly and correctly to prevent air leaks.
- Install New Foam and Felt Filters: Place the new foam filter first, followed by the felt filter, into their respective slots. Ensure they fit snugly.
- Close Compartments: Securely close all filter compartments. Ensure they latch properly before using the vacuum cleaner.

Operating Principles
These replacement filters are designed to maintain the optimal performance of your Shark vacuum. The HEPA filter traps fine dust particles and allergens, preventing them from recirculating into your home's air. The foam and felt filters provide an additional layer of filtration, protecting the motor from larger debris and extending the life of the HEPA filter.

Maintenance and Replacement
To ensure your vacuum cleaner continues to operate at peak performance, regular maintenance of the filters is essential. These filters are designed for replacement rather than extensive cleaning.
- Replacement Frequency: It is recommended to replace the HEPA, foam, and felt filters every six months. This frequency may vary depending on your usage habits and the amount of dust and debris collected.
- Signs of Replacement: Replace filters sooner if you notice a decrease in suction power, unusual odors from the vacuum, or visible damage/excessive dirt on the filters.
Troubleshooting
If you experience issues with your vacuum cleaner after filter replacement, consider the following:
- Reduced Suction: Ensure all filters are correctly installed and seated firmly. Check for any blockages in the vacuum's hose or brush roll.
- Unusual Noises: Verify that the filters are not obstructing any moving parts and that all compartments are securely closed.
- Dust Leakage: Confirm that the HEPA filter is properly sealed within its housing and that the foam and felt filters are correctly positioned.
