Maintenance instructions from Thomas:

Cleaning:
Clean the filter thoroughly every 3 months . This prevents additional resistance when drawing in air. Rinse the filter carefully with water and allow it to dry completely before reinserting it.

Replacement:
Replace the filter at least once a year , even if it still looks clean. Over time, the filter can become less effective due to wear and clogging, which can lead to reduced air pump performance.
