VEVOR Range Hood Insert, 30 Inch Built-in Kitchen Vent Hood, 800CFM Stainless Steel Stove Hood, with Gesture & Touch Control, LED Light, Baffle Filters, 4-Speed Exhaust Fan, Ducted/Ductless Convertible

it didn’t come with a grease collection box. the grease gets trap in the vents and they are very easy to remove and clean. this range is powerfull

There is no grease box, such as in a commercial hood. You just bring down the vents and place them in your dishwasher. They come out great. There will be some water left. I shook mine in the sink, for half hour or so then ,put them back into the hood. I use Simple Green, full strength to clean the stainless trim on the outside.
