A: General FAQs

Q: How do I convert my unit to ductless?

A: To convert your unit to a ductless operation and recirculate the air back into the room:

  1. Purchase the necessary carbon filter kit found online at www.cosmoappliances.com/product-category/parts-and-accessories/range-hood-parts/filters/. This filter is not included with your purchase and must be purchased separately.
  2. Use the included air vent caps to cover the rear and top (if applicable) air vents.
  3. Remove the aluminum filters on your range hood.
  4. Install the carbon filter by pressing it against the motor and twisting clockwise. It will create a tight seal.
  5. Loosen the set screw on the switch next to the carbon filter’s location and slide it to the recirculating icon.
  6. Tighten the switch’s set screw.
  7. The air will now recirculate into the room through the vents on the front of the range hood.
