The Honeywell replacement air filter model number FC100A1011 is the OEM replacement filter media for Honeywell models F100B1024, F100F1020, F100F2036, and F150E1018 whole house Electronic Air Cleaners.
The size of the FC100A1011 air filter is approximately 19 1/2" x 19 7/8" x 4 3/8". The FC100A media filter offers MERV 11 performance at 492 FPM with lower pressure drop at no additional cost.
Honeywell recommends the replacement of the air filter media every six (6) months before the heating and cooling seasons. Adjust the schedule to your needs, but at least replace the filter annually. Regular replacement of the air filter will maximize the efficiency of your heating and cooling system.
If the F100 unit includes an Airwatch Indicator, replace the media at least once a year or when the built-in pressure sensors in the F100 door detect that airflow is impaired and the filter requires cleaning. This condition causes the indicator light on the F100 door to begin flashing and the transmitter to send a signal to the wall-mounted RF Indicator that the filter needs replacing.
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 five (5) filters.
