F100 versus F200 versus F300
Honeywell uses the same chassis for the F100, F200, and F300. The chassis is made in four sizes 16x20, 16x25, 20x20, 20x25. They all accept the same media filters or can be fitted with electronic cells.
The F100 is the basic model that comes with a filter rated at Merv 11 (FC100A1045). The F100 is available with or without the W8600A wall mount indicator that simply provides a reminder to change the filter based on calendar days. The F100 filter will also fit in the F200.
The F200 model uses the same chassis as the F100 but the access door has a sensor. The F200 door senses the pressure drop across the filter and transmits the status to the W8600B wall mount indicator. The W8600B will indicate a filter change is needed based on the differential pressure drop. The F200 comes with a filter rated at Merv 13. The F200 filter will also fit the F100 model.
The earlier model F35F and F25F also used the same chassis and door as the F100. The F25 and F35 used the current F100 or F200 replacement filters.
