3. Operating Principles
Once installed, the Fdit 3MM White Air Filter Cotton operates as a passive filtration medium. Air passes through the cotton material, and airborne particles are trapped within its fibrous structure. The 3MM thickness and high-density cotton material contribute to its effectiveness in capturing dust, pollen, and other suspended particulates, thereby improving air quality.

5. Troubleshooting
If you experience issues with your filtration system after installing the Fdit 3MM White Air Filter Cotton, consider the following:
- Reduced Airflow:
- Check if the filter cotton is correctly installed and not obstructing the air intake/output.
- The filter might be saturated with particles. Replace it if it appears dirty.
- Ensure the filter is cut to the correct size and not folded or bunched up.
- Poor Filtration Performance:
- Verify that the filter cotton is properly seated and there are no gaps around its edges allowing air to bypass it.
- Consider if the filter needs replacement due to heavy particle load.
- Ensure the filter cotton is appropriate for the specific type of particles you are trying to filter. This product is a primary filter.
- Unusual Odors:
- While the filter cotton itself is tasteless, if new odors appear, ensure the filter is clean and properly installed.
- Check other components of your device for potential odor sources.
