Where is my F50F Model Number
Order parts based on your model number. The F50 model number is located on the inside of the door.
Otherwise order parts based on the overall size of your cells. The F50F came in 5 sizes. The smallest model has one cell 12½x20. The two cell models are 16"x20", 16"x25", 20"x20", 20"x25".
If your air cleaner was manufactured by a different company and looks like ouu photos, then it is a Honeywell air cleaner. Honeywell also had an earlier F50E that was similar. The most noticeable difference between the F50F and the earlier F50E is the size of the powerbox. The F50F power box runs the full length from front to back. The F50E power box is half the length.
The F300 is identical to the F50F but with different paint color.

Simple Power Supply Test Procedure
Troubleshoot Problem:
- The neon indicator light is not coming on
- The cells never spark
- Power box switch is ON
- Door is tight in place
- Blower is ON
- Verify Power is Present.
Unplug the power box cord and operate a drop-light in the 3-prong receptacle verifying an acceptable voltage and current. - Check for Shorted Cells
A shorted cell can prevent the indicator light from coming on. Remove both cells, with door back in place operate without cells. If the unit now appears OK with indicator light ON, then the cells have a problem. - Operate without cells
- Check cells for broken wires
- Check cells for bent plates
- Check with one cell at a time (align cell with contacts)
- Replace or Repair Power Box.
If the power box is plugged in to 120v and the Neon indicator still does not light without the cells, then the problem is in the power box.
- Check the on/off switch, interlock door switch and wiring.
- Bypass the Air Flow Switch (AFS), The AFS is a sensor that signals the power supply when air flow is present. Disabling the AFS will simulate the ON state. Using a jumper wire, ground AFS resistor to the chassis, see AFS Tech Notes.
- Replace Air Flow Switch, if the Neon indicator lights and unit appears to work with the AFS disabled.
- Replace Power Supply, if the Neon indicator does not light with the AFS disabled and no cells to short the output.
- Neon problem, is not likely if test button does not spark. The neon lamp voltage should measure 125 vdc.
