2. Installation (Setup)
Follow these steps to properly install your MOUNTO HEPA500 replacement filter:
- Safety First: Ensure the air scrubber unit is unplugged from the power source before beginning any maintenance or installation.
- Access Filter Compartment: Locate and open the filter access panel on your air scrubber. Refer to your air scrubber's manual for specific instructions on accessing its filter compartment.
- Remove Old Filter: Carefully remove the used HEPA filter. Dispose of the old filter according to local regulations.
- Insert New Filter: Place the new MOUNTO HEPA500 filter into the compartment. Ensure the filter is oriented correctly, typically with the airflow arrow (if present on the filter or compartment) pointing in the direction of the air scrubber's airflow. The gasket on the outflow side should create a tight seal.
- Secure Compartment: Close and secure the filter access panel.
- Restore Power: Plug the air scrubber back into the power source.

3. Operating Principles
The MOUNTO HEPA500 filter functions as a critical component in your air scrubber system. It utilizes advanced pleated filter media to effectively remove a wide range of airborne contaminants. The H13 HEPA standard ensures that the filter captures 99.97% of particles as small as 0.3 microns, including dust, pollen, mold spores, pet dander, and other microscopic allergens and pollutants. This high level of filtration contributes to improved indoor air quality in various environments, from residential to commercial and industrial settings.
4. Maintenance
Regular maintenance of your HEPA filter is essential for optimal performance of your air scrubber.
- Inspection: Periodically inspect the filter for visible signs of dirt, debris, or damage. The frequency of inspection depends on the usage environment and air quality.
- Replacement: The HEPA filter should be replaced when the air scrubber's filter indicator light illuminates, or when you notice a significant decrease in airflow, or increased noise from the unit. In typical usage, HEPA filters may last several months to a year, but this can vary greatly based on air quality and operational hours.
- Disposal: Used filters may contain captured pollutants. Handle and dispose of them responsibly according to local waste disposal guidelines.
5. Troubleshooting
If you encounter issues with your air scrubber after filter replacement, consider the following:
- Reduced Airflow:
- Ensure the filter is installed correctly and seated firmly within its compartment.
- Check for any obstructions in the air intake or exhaust vents of the air scrubber.
- If the filter is heavily soiled shortly after replacement, the environment may be exceptionally dusty, requiring more frequent changes.
- Filter Indicator Light Remains On:
- Verify that the new filter is correctly installed.
- Some air scrubbers require a manual reset after filter replacement. Consult your air scrubber's manual for specific reset procedures.
- Unusual Odors:
- While HEPA filters primarily capture particles, strong odors might indicate a need for an activated carbon pre-filter (if your system supports one) or a new HEPA filter if it has absorbed significant odors over time.
