When Should I Replace the Air Purifier Filters

When one of the filters is almost full and has to be cleaned or replaced, the appropriate filter replacement light starts to flash. We suggest replacing the filter every 6 months. Normally, the light flashes after running 6 months. 

The filters' lifetime is based on your house air quality and usage time (assuming 24h being on). The suggested replacement period is just for your reference. Using the appliance in a humid environment will reduce the lifetime of the activated carbon filter and HEPA filter.
