Installation Guide
Follow these general steps to replace the filters in your Shark vacuum cleaner. Refer to your vacuum's original instruction manual for specific compartment locations and detailed instructions.
- Power Off and Unplug: Always ensure your vacuum cleaner is turned off and unplugged from the power outlet before performing any maintenance or filter replacement.
- Locate Filter Compartments: Identify the filter compartments on your Shark vacuum. Typically, the foam and felt filters are located in the pre-motor filter housing, and the HEPA filter is in the post-motor filter housing.
- Remove Old Filters: Open the filter compartments and carefully remove the old, dirty filters. Dispose of them according to local regulations.
- Insert New Filters: Place the new Leadaybetter foam and felt filters into their designated slots in the pre-motor housing. Ensure they are seated correctly. Insert the new HEPA filter into the post-motor housing, making sure it fits snugly.
- Close Compartments: Securely close all filter compartments. Ensure they are latched properly to prevent air leaks.
- Resume Operation: Plug in your vacuum cleaner and turn it on. You should notice improved suction and air quality.
Filter Functionality
The Leadaybetter replacement filters are engineered to provide multi-stage filtration for your vacuum:
- Foam Filter: Captures larger particles and debris, protecting the motor.
- Felt Filter: Traps finer dust and particles that may pass through the foam filter.
- HEPA Filter: The high-efficiency particulate air (HEPA) filter is designed to capture 99.97% of airborne particles as small as 0.3 microns, including pet dander, pollen, and dust mites, ensuring cleaner exhaust air.

Maintenance and Care
Regular cleaning and timely replacement of your filters are crucial for maintaining your vacuum's suction power and filtration efficiency.
Cleaning Instructions:
- The foam and felt filters are washable. Tap off loose dirt, then rinse them under running water until the water runs clear.
- The HEPA filter can also be rinsed under running water. Do not use soap or detergents.
- Important: Allow all filters to air dry completely for at least 24 hours before reinstalling them into your vacuum. Do not use a dryer or other heating devices, as this can damage the filters.
Recommended Replacement Schedule:
- Cleaning Frequency: It is recommended to clean the foam and felt filters every 2 to 3 weeks, depending on usage. The HEPA filter should be cleaned monthly.
- Replacement Frequency: For optimal performance, replace the foam and felt filters every 2 to 3 months. The HEPA filter should be replaced every 6 months to 1 year, or sooner if heavily soiled or if you notice a decrease in vacuum performance or an increase in odors.

Troubleshooting
If you experience issues with your vacuum after replacing the filters, consider the following:
- Reduced Suction: Ensure all filters are installed correctly and are completely dry. A wet filter can severely restrict airflow. Check for any blockages in the vacuum hose or brush roll.
- Unusual Noises (e.g., Screeching): This can sometimes indicate an improperly seated filter or a filter that is not fully dry. Re-check the installation of all filters. If the noise persists, consult your vacuum's original manual for further troubleshooting.
- Persistent Odors: If odors persist after cleaning and replacing filters, it may indicate a need for more frequent filter changes or a deeper cleaning of other vacuum components (e.g., dust cup, hose).
- Filter Not Fitting: Double-check the compatibility section and your vacuum's model number. Ensure you have purchased the correct replacement filters for your specific Shark model.
