What about replacing the filters?
The HEPA 12 filter for particle removal and the filter for gas cleaning need to be checked regularly, and it is recommended that they are replaced at least every six months. However, every home is different. Check the filter regularly to see if it's dirty. An LED indicator also illuminates when you need to check the filters and possibly replace them. To open the unit, simply pull the pull-tag on the right side and loosen the pre-filter. Remove the pre-filter to access the particle and/or gas filter behind for replacement.
