The Honeywell replacement air filter model number FC100A1003 is the 16 x 20 x 5 OEM replacement filter media for Honeywell models F100F1004, F100B1008, F150E1000, F100F2028 whole house Air Cleaners.
The size of the FC100A1003 air filter is approximately 16" x 19 5/8" x 4 1/2". The FC100A media filter offers MERV 10 performance at 492 FPM with lower pressure drop at no additional cost.
Honeywell recommends the replacement of the air filter media every six months, before heating season and before cooling season. 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.
For instructions on how to change your air cleaner filter and reset the indicator, please refer to your units Owner’s Guide.
