It should be replaced at least every 3 months. If there are heavy concentrations of odors, smoke, or large particles in the home, you may need to change the carbon pre-filter more often. For instructions on how to replace your pre-filter, refer to section "Removing/Changing the Filters" in this manual. Note: We do not recommend operating the air purifier without the carbon pre-filter.
