Cleaning and Maintenance Tips for Honeywell Pre Filters: Clean your pre filters every 4-6 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 the mesh screen to rip away from the aluminum frame. Always allow the pre filters to dry completely before placing them back in the air cleaner.  Damaged pre filters, especially with the screen hanging loose from the frame, should never be used.  When your heating and cooling system is on air pressure from the fan motor may pull the loose screen into the cells causing arcing.  This can result in constant and loud snapping sounds at best and in some cases severe damage to your electronic air cleaner.
