Only the pre-filter is washable. To clean, separate the pre-filter from the combo carbon and HEPA filter. Use the brush attachment on your vacuum cleaner to remove lint and dirt from all three filters. If necessary, you can wash the pre-filter in warm water with mild dish detergent. Make sure it is completely dry before reattaching it to the combo carbon and HEPA filter.
