3. Operating Instructions
Once installed, the B84B HEPA filter operates automatically as part of your Vacmaster industrial vacuum cleaner's filtration system. It is designed to capture a wide range of particles, including dust, debris, and fine allergens, ensuring cleaner exhaust air and protecting the vacuum's motor.
4. Maintenance
Regular cleaning of your HEPA filter is crucial for maintaining optimal vacuum performance and extending the filter's lifespan. This filter is washable and reusable:
- Removal: Unplug the vacuum cleaner and carefully remove the filter as described in the installation steps.
- Cleaning: Gently tap the filter to dislodge loose debris. For a more thorough clean, rinse the filter under running water (preferably lukewarm) until the water runs clear. Do not use harsh detergents or brushes that could damage the filter media.
- Drying: Allow the filter to air dry completely before reinstalling it. This may take 24-48 hours depending on humidity. Do not use heat sources (like a hairdryer) as this can damage the filter material. Ensure it is bone dry to prevent mold growth and maintain filtration efficiency.
- Reinstallation: Once completely dry, reinstall the filter following the setup instructions.
Note: The filter's color may vary slightly from images due to manufacturing or display differences, but this does not affect its functionality.

5. Troubleshooting
- Reduced Suction: If your vacuum cleaner experiences reduced suction, the filter may be clogged. Remove and clean the filter as described in the Maintenance section. If suction does not improve after cleaning, the filter may need to be replaced.
- Unusual Noises: Ensure the filter is correctly seated and securely installed in its compartment. A loose filter can cause vibrations and unusual noises.
- Dust Escaping: If dust is escaping from the vacuum's exhaust, verify that the filter is properly installed and that there are no tears or damage to the filter media. A damaged filter should be replaced immediately.
