According to the user manual, the PPI30 filter in the LENA LIGHTING UV-C Sterilon Air Z1 should be checked after the first 4 months of device operation. If the filter is dirty and blocking the airflow, it should be replaced every 4 months. If the filter is not dirty during the first inspection, its cleanliness should be checked every 6 months (or 1000 hours) of operation and replaced if dirt appears. Regular maintenance and filter replacement ensure the optimal performance of the device in disinfecting the air.
