To keep your VALBERG 972442 Purifying Fan running at its best, regular filter is key. The pre-filters should be cleaned every two weeks. For the HEPA filter, it's recommended to replace it every six months, especially if the fan is used frequently. The fan has a filter replacement icon that will light up to indicate when it's time for a new HEPA filter. Here's a simple guide to cleaning and replacing the filters: Cleaning the Pre-Filters: Remove the air inlet covers and the pre-filters. Use a vacuum cleaner or a soft, damp sponge to clean the pre-filters. Make sure they are completely dry before you put them back in. Replacing the HEPA Filter: Take out the old HEPA filter and put in the new one. Resetting the Replacement Icon: To reset the filter replacement icon, press and hold the filter replacement icon button until it turns off. Following these steps helps maintain the fan's performance, reduces the chance of repairs, and extends the life of your VALBERG 972442 Purifying Fan.
