Substitute hoods can be mounted under an upper cupboard or mounted on the wall. Handy if you do not have much room for a large hood. A substructure hood is not very wide with a standard width of 60 centimeters. This fits this type of hood in almost every kitchen. Due to its extraction capacity, the hood is best suited for small or medium kitchens. Use this hood above a hob with 4 cooking zones so that all vapors are collected.
