A wall-mounted range hood is a range hood with mount which you can mount on the wall. There are 3 types of range hoods: slanted, flat, and standard. The most striking wall-mounted range hood is a slanted model. This model runs upwards at an angle, so you won't bump your head anymore. The difference between a flat and standard model is that the flat model is flat at the top. The standard dimensions for a mounted range hood are 60cm and 90cm wide.
