This VH60WH Wall Mounted Visor Cooker Hood Extractor in white combines style with functionality and will suit any large appliance in any type of kitchen. This product boasts high levels of efficiency and power, as well as having a low level of noise output. Top ducting means the hood can be ducted over the top of your kitchen units. The main reason for extracting air through a duct to a vent in your wall or to pass extracted air through carbon filters before re-circulating back into your kitchen is to remove unwanted steam and smells from your kitchen.
