To clean a ductless range hood, you will typically remove the screw holding the grease filter retainer. Next, release the retainer by turning it, pulling toward you and away from the fan. Finally, wash your filter in the dishwasher or a hot detergent solution, dry it and then screw it back in place. Always check your owner’s manual before disassembling or cleaning any part of your hood as instructions may vary.
In general, some cleaning solutions to avoid when cleaning the exterior surface of the filter include: Soap-filled scouring pads, abrasive cleaners, cooktop polishing creme, steel wool, gritty washcloths or paper towels. Additionally, so as to not damage the stainless steel, avoid cleaners that contain chlorine.
