Slide the power switch on the front of the Oreck air purifier over to the "Off" position. Unplug the power cable running from the back of the purifier to your electrical wall outlet.
Lift up the front end of the air purifier until the small plastic thumbscrew on the bottom edge is visible. Manually turn the screw counterclockwise with your fingers until it pops out of the air purifier. Set the purifier back down.
Grip the plastic grill on the front of the purifier and slide it toward you. Set the grill and its attached collector cell on a flat work surface. Grip the charcoal filter on the back of the collector cell and pull it upward to remove it from the cell.
Grab the rectangular plastic filter screen inside the air purifier and slide it out of the purifier. Locate the fragrance cartridge release switch on the control panel at the right side of the air purifier. Slide the switch over to the left to eject the fragrance cartridge.
Pull the fragrance cartridge out of the device to finish disassembling the Oreck air purifier.
- Oreck air purifiers use a "polarized" style electrical cable that only fits into the wall socket in one direction. If the cable won't fit in the socket, turn it over and insert it into the socket again.
- Cleaning off the filter screen inside the air purifier with a damp cloth extends the life of the unit, but the charcoal filter cannot be cleaned. Instead, the charcoal filter connected to the collector cell needs to be replaced every two months. Replacement filters are available directly through Oreck.
