Stainless Steel Filter Maintenance

CAUTION

• The Ionizer Wire may break if pressure is applied to it. Be careful when handling or cleaning!
• NEVER insert a wet Filter into the unit. Doing so may permanently damage the electrical components!

It may be necessary to clean the Filter more or less frequently  depending on the air quality in your environment. Your Sharper Image® Ionic Comfort Quadra Stainless Steel Filter Assembly may be machine washed in your dishwasher or manually in your sink.  Please follow these steps to clean the Stainless Steel 
Filter Assembly

1. Press the Power Button to turn the unit off.
2. Unplug the unit from the receptacle outlet.
3. Open the Filter Door and remove the Stainless Steel Filter Assembly by firmly gripping the Filter Handle and pulling the assembly out of the unit.
   Dishwasher Cleaning
   Remove the Honeycomb Pre-Filter from the bottom of the Stainless Steel Filter Assembly and place both components on the bottom tray of your dishwasher. Wash the filters as you would dishes. If you find that the filter’s Stainless Steel Filter Plates do not get completely clean with one wash cycle, increase the wash cycle time or wash the Filters for a second time. Note that some phosphate-free dishwasher detergents can cause staining to the aluminum filter-frame. Staining will not affect performance. If in doubt, use water-only cleaning or clean in sink. The normal dishwasher drying cycle should be an effective drying time.
   Note: Do not allow the dishwasher rack to bend the Stainless Steel Filter Plates or break the lonizer Wire. Care must be taken when positioning in the dishwasher. Your air purifier will not function properly if the Stainless Steel Plates touch each other or the lonizer Wire breaks.
   Sink Cleaning
   Remove the Honeycomb Pre-Filter from the Stainless Steel Filter Assembly and place both components in your sink. Rinse to remove large debris. Submerge both filters in warm water that contains standard dish washing soap. Allow the filters to soak for at least 15 minutes, drain the sink and rinse the filters with cold water.
   Note: You may use a small-headed scrub brush to clean stubborn residue between the Stainless Steel Plates or Honeycomb Pre-Filter. However, take care not to bend the Stainless Steel Plates or apply pressure to the lonizer Wire.
4. Allow the Stainless Steel Filter and Honeycomb Pre-Filter to dry completely before inserting them back into the lonic Comfort Quadra unit. They can be dried either in the dishwasher or allowed to air dry. Typically, evaporative air drying can take 12-24 hours, depending on humidity and temperature.
5. Install the Honeycomb Pre-Filter back into the bottom of the Stainless Steel Filter Assembly. Don't worry: both ends are the same, so it can be inserted either way. Never operate the unit without the Honeycomb Pre-Filter.
6. Insert the cleaned and dried Stainless-Steel Filter Assembly back into your Sharper Image lonic Comfort Quadra unit.

CAUTION: If you have reinstalled the Stainless Steel Filter Assembly after cleaning and drying, and hear "crackling" after turning it on, your filter is still wet. Turn the unit off, remove the Filter Assembly and allow it to dry longer.
