How to Clean an Oreck Air Purifier

Oreck offers two types of air purifiers -- one with HEPA filters that you'll need to replace periodically, and one with permanent Truman Cell filters, which never need replacing but require occasional cleaning. To make sure the permanent filter continues to work properly and efficiently, clean it as needed. Oreck Truman Cell air purifiers have an indicator lights that comes on every 30 days. Go ahead and clean the rest of the appliance as part of regular maintenance.

Step 1

Unplug the Oreck air purifier before cleaning any part of it to avoid the possibility of electric shock.

Step 2

Clean the air purifier's filter every time the 30-day indicator light turns on. Remove the filter from the appliance and place it in a tub or sink, or on a hard, towel-covered surface such as a kitchen counter. Add a few drops of a gentle dish-washing liquid to a bowl or bucket of warm water. Dip a soft cloth or sponge into the soapy water and wring it out. Wipe the filter down with the cloth or sponge, re-wetting it as needed. Rinse the filter with water and allow it to air dry before inserting it back into the purifier.

Step 3

Wipe down the outside portion of the air purifier with a clean, damp cloth to remove any debris. Follow up with a mild, nonabrasive cleanser for more thorough cleaning or to remove stubborn stains.

Step 4

Maintain the purifier's air inlet and outlet every two months by brushing it clean with a soft brush. Don't allow any dust to fall into the air purifier.

Step 5

Clean the air sensor every two months. Open the air sensor cover, which is located on the the side of the appliance, and brush the air inlet vent, the air outlet vent and the air sensor with a soft brush to remove dust and debris. Slightly dampen a cotton swab with water and use it to gently clean the lens, the dust inlet and the dust outlet. Run a dry cotton swab over the parts to remove any moisture.
