Filter Maintenance - Every 3 months, remove the H13 HEPA Filter from the unit and dry it under direct sunlight. Use a vacuum cleaner or soft brush to remove dust buildup on the filter. This will help to extend the life of the filter and maintain its performance. - The H13 HEPA Filter is not washable.
