What’s the range hood:
A range hood consists of three main components: a capture panel or skirt to trap rising gases, a fan, and one or more grease filters. Range hoods are also known as extractor hoods, fume extractors and ventilation hoods,etc.
There are two types of range hoods: ducted range hoods and ductless range hoods. A ducted range hood should be installed in an area where a duct system is already installed to keep the polluted air out of your kitchen. For ductless range hood, the filters removes odor and smoke particles, often using activated charcoal, then release the cleaned air into the kitchen. So it can be installed almost anywhere in the kitchen.

Some developments in range hood history:
The range hoods were first invented in 1926 by Theodore R.N. Gerdes, who applied for a patent for “ventilating hood for ranges, etc.” He used a fan to catch the escaping fumes.

Two years later, Lloyd W. Ray filed for a patent for a stove hood “particularly design for use in connection with a stove or hod plate such as is used in hamburger stands and the like and provision is made for separating the grease from the vapors as well as to carry oil hot air from underneath the hot plate.”

Since these rang hoods needed ventilation fans, Henry Broan started his business manufacturing ventilation fans in 1932, and Broan-NuTone LLC is a leader in ventilation fans and range hoods.

Vent-A-Hood®,founded in 1933, was the first manufacturer of home cooking ventilation and range hoods.

Today's range hoods incorporate many of these incremental developments into modern, beautiful additions to your kitchen.
