4. Installation (Filter Replacement)

5. Driftsmæssige overvejelser
Once the new filter is installed, your Sejoy KJ100F Air Purifier is ready for operation. The filter works continuously to purify the air as the device runs. Ensure the air purifier is placed in an open area, away from obstructions, to allow for optimal airflow and filtration efficiency.
6. Vedligeholdelse
To maintain optimal air purification performance, it is recommended to replace the Sejoy KJ100F filter every 6 til 8 måneder. This timeframe may vary depending on air quality, usage frequency, and environmental factors (e.g., presence of pets, smoking, high pollution levels). Regular replacement ensures the filter's efficiency in capturing pollutants and odors.
Do not wash or attempt to clean the HEPA or activated carbon layers of the filter, as this can damage the filtration media and reduce effectiveness. Only the pre-filter layer might be gently cleaned if accessible and designed for it, but for this integrated 3-in-1 filter, full replacement is recommended.
7. Fejlfinding
If you experience issues after replacing the filter, consider the following:
- Reduceret luftstrøm: Ensure the filter is correctly seated and the base cover is securely tightened. Check if the plastic packaging was fully removed from the new filter.
- Vedvarende lugte: If odors persist shortly after replacement, verify that the new filter is genuine Sejoy KJ100F and properly installed. Extremely high levels of pollutants might require more frequent filter changes.
- Filterindikatorlampen forbliver tændt: Refer to Step 7 in the Installation section to ensure the filter reset procedure was performed correctly. If the light still persists, consult your air purifier's main user manual.
- Usædvanlige lyde: Ensure the filter is not loose inside the purifier. Re-open the base, re-seat the filter, and close securely.
