Cleaning Tips: Clean your pre-filters every 2-4 months. Pre-filters are very delicate and care should be used while cleaning them. Do not clean pre-filters in the dishwasher. Tap water from the sink or an outside hose should work fine. Do not whip or shake the pre-filters when drying as this could cause ripping. Always allow the pre-filters to dry before placing them back in the air cleaner.
