3. Installation Instructions
Follow these steps to properly install or replace the activated carbon prefilter in your InvisiClean Claro Air Purifier IC-4524:
- Power Off and Unplug: Before beginning, ensure the air purifier is turned off and unplugged from the power outlet to prevent electrical hazards.
- Locate Filter Compartment: Refer to your InvisiClean Claro Air Purifier's main instruction manual to locate and open the filter compartment. This is typically on the back or side of the unit.
- Remove Old Prefilter: Carefully remove the existing activated carbon prefilter. It may be attached to the main HEPA filter or sit in a separate slot. Note its orientation.
- Prepare New Prefilter: Unpack the new InvisiClean Activated Carbon Prefilter.

- Restore Power: Plug the air purifier back into the power outlet and turn it on.
- Reset Filter Indicator (if applicable): If your air purifier has a filter replacement indicator, follow the instructions in your air purifier's manual to reset it. This usually involves pressing and holding a "Filter Reset" button for a few seconds.

4. Maintenance and Replacement
Regular maintenance of your prefilter is essential for maintaining air purifier efficiency and extending the life of your HEPA filter.
4.1. Cleaning the Prefilter
The activated carbon prefilter should be cleaned regularly to remove accumulated dust and debris. This can be done by:
- Gently vacuuming the surface of the prefilter with a brush attachment.
- Wiping the prefilter with a dry cloth.
- Do not wash the activated carbon prefilter with water, as this can damage the carbon material and reduce its effectiveness.
Recommendation: Clean your prefilter monthly, or more frequently if the air quality is poor or if you notice a decrease in air purifier performance.
4.2. Replacing the Prefilter
While the prefilter can be cleaned, it has a limited lifespan for odor reduction and particle capture. It should be replaced periodically to ensure optimal air purification.
- Replacement Frequency: Replace the activated carbon prefilter every 1-3 months, depending on usage and environmental conditions. Heavy use, pets, or smoking in the area may require more frequent replacement.
- Signs of Replacement: Replace the prefilter if you notice a persistent odor, reduced airflow, or if the filter appears heavily soiled and cleaning does not restore performance.
