F50F1065 Parts


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 smalest model has one cell 12½ x 20.
The two cell models are 16 x 20, 16 x 25, 20 x 20, 20 x 25 inch.

If your air cleaner looks like our photos, then it is a Honeywell. Honeywell also had an earlier F50E that was similar. The most noticable difference between the F50F and the earlier F50E is the size of the power box. The F50F power box runs the full length from front to back. The F50E power box is half the length. More F50E ...

The F300 is identical to the F50F but a different paint color.

Permatron manufactures the pre-filters for the brand name electronic air cleaners. Permatron also manufactures a premium line of electrostatic pre-filters and activated carbon filters. Permatron has engineered filter upgrades for the F300 and F50 utilizing the latest advancements in filtration technology.

Simple Honeywell Power Supply test Procedure
Your problem is:
   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
  1. 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.
  2. 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.
    1. Operate without cells
    2. Check cells for broken wires
    3. Check cells for bent plates
    4. Check with one cell at a time (align cell with contacts)
  3. 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.
    1. Check the on/off switch, interlock door switch and wiring.
    2. 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.

Choosing the replacement power box may be dependent on the series. If you do NOT have the optional wall mounted Remote Performance Indicator (W8600), the series does not matter.

If you are replacing a power box of any series and do NOT have a W8600, we recommend choosing the Series 2 power box.

F50F Series 1 was manufactured from 94 to 97. The Series 2 was manufactured 98 thru 06.

The Series 1 power box comes with a 4 connector terminal strip on the left side of the box. The connector would be used for the optional W8600E.

The Series 2 power box has a knock-out for a terminal strip. The terminal strip would be included with the optional W8600F. The F50F Series 2 power box is the same used in the current


The Honeywell warranty for F300 replacement parts is 2 years.  Our customers simply need to ship us the defective part.  We test and confirm defective.  We then ship back a brand new part at no charge.
