How often should I clean or replace my LUMME LU-3216 vacuum cleaner filter for best results?

[OJosephine]

To keep your LUMME LU-3216 vacuum cleaner running at its best, pay close attention to the filter. The filter should be cleaned whenever it appears dirty. For optimal performance, replace the filter after approximately 100 hours of use. Remember to hand-wash the filter when it is full of dust; do not use a washing machine or an electric heater. Always air-dry the filter completely before reinstalling it. Regular filter maintenance is key to ensuring your LUMME LU-3216 continues to provide efficient cleaning.
