Note: The 50000293-003 will not fit the F50A or F50E series systems. These high-efficiency charged post filters boost the efficiency of any Honeywell electronic air cleaner with negligible effect on pressure drop. The 50000293-003 post filter size is approximately 20" x 10". Two replacement filters are required for each 20" x 10" F300 or F50F electronic air cleaner installed in your HVAC system. Maintenance & Care: Honeywell recommends the replacement of the post-filter every six (6) months. Regular replacement of the post filter will maximize the efficiency of your electronic air cleaner. The post filter is optional, boosting the air cleaner's efficiency. Do not wash the post filter, which will neutralize the factory-applied charge. Please refer to your unit's Owner's Guide for instructions on changing your air cleaner filter and resetting the indicator. This package ships with 2 x 2 packs of post filters (4 Filters for an Annual Supply).
