Let’s get started.

  1. First, you want to make sure the unit has been unplugged and the power is switched to OFF.
  2. Next, you have to dismantle the front panel grill by loosening the four screws fixing the grill of the front panel.  Once removed, you can safely remove the grill.
  3. Dismantle the knobs by loosening the screws by fixing the knobs with a flat-headed screwdriver.  Once the screws are loosened, you can remove the knobs safely.
  4. Remove the Hepa filter by loosening the two screws on the back which attack the Hepa filter to the cabinet/housing.  You should be able to remove the Hepa filter, the photo catalytic metallic filter and the ozone plates.  Note: depending on your model, your model will or won’t have all of these parts.
  5. Dismantle the housing by carefully flipping the air purifier upside down on a gentle, hard surface.  Loosen and remove the two bottom screws.  Now safely remove the housing.
  6. Remove the front metal bar by removing the two screws holding the front metal bar in place.
  7. Remove the fan blade by cautiously pulling the fan blade towards you gently rocking it side to side, so that when it is pulled out, it won’t hit the two ionizer prongs in front of it.
  8. Dismantle the support bar by loosening the four screws which are fixing the support bars.  Safely remove the support bar.
  9. Loosen the wires by cutting the bundling strings.
  10. Remove the fan wire by fining the wire connected to the fan motor on the PCB panel board.  The slot with the plug is named “fun”.
  11. Finally, remove the fan motor using a screw driver to remove the screws from the motor.  Use pliers to hold the bolts in place while you’re unscrewing the screw.

You should now be able to completely remove the fan motor and replace it with a new fan motor.  In order to put the air purifier back together, follow the steps in reverse order.
