Setup and Installation
Follow these steps to correctly replace the filters in your AlorAir CleanShield HEPA 550 Air Scrubber:
- Power Off: Ensure the AlorAir CleanShield HEPA 550 Air Scrubber is turned off and unplugged from the power source before attempting any filter replacement.
- Open the Unit: Locate and unlatch the clips securing the filter compartment cover. Carefully open the cover to access the filters.
- Remove Old Filters: Gently remove the used pre-filter, HEPA filter, and activated carbon filter. Dispose of them according to local regulations.
- Insert New Filters: Place the new HEPA/Activated Carbon filters into the unit. Ensure they are seated correctly and the "FRONT" indicator on the filter is facing the correct direction (typically towards the air intake). No modification of the air scrubber is required; simply place the new filter.
- Secure the Cover: Close the filter compartment cover and secure all latches firmly.
- Check Indicator Light: If the "Change HEPA Filter" indicator light was on, it should reset after proper filter replacement. If it remains on, ensure filters are correctly installed and the unit is properly sealed.

Operating Instructions (Filter Function)
Once the new filters are installed, the AlorAir CleanShield HEPA 550 Air Scrubber is ready for operation. The filters work in conjunction with the air scrubber to:
- Capture 99.97% of airborne particles as small as 0.3 microns, including dust, pollen, pet dander, and mold spores.
- Absorb odors, smoke, and volatile organic compounds (VOCs) through the activated carbon layer.
- Maintain optimal air quality in various environments, including construction sites, water damage restoration areas, and during home renovations.
Refer to your AlorAir CleanShield HEPA 550 Air Scrubber's main instruction manual for detailed operating procedures of the unit itself.
Maintenance
Regular filter maintenance is crucial for the efficiency and effectiveness of your AlorAir CleanShield HEPA 550 Air Scrubber.
- Replacement Frequency: It is recommended to change the HEPA/Activated Carbon filter every 6-8 months, depending on usage and air quality conditions.
- Indicator Light: Always change the Activated Filter when the "Change HEPA Filter" indicator light on your air scrubber illuminates.
- Remediation Use: When using the CleanShield for remediation purposes (e.g., water damage, mold), replace both filters at the same time and thoroughly clean the machine between jobs to prevent cross-contamination.

Troubleshooting
If you encounter issues after replacing your filters, consider the following:
