Description
An extractor hood consists of three main components: a skirt or capture panel to contain the rising gases (also known as the "effluent plume"), a grease filter, and a fan for ventilation.

Filters
Filters remove most odors and particulates, including grease, from the vented air. There are three main types of filter:
• Mesh or cassette filters are made from aluminium mesh strips placed one over the other. They are highly effective in the capture and removal of oil and grease from smoke of both ducted and ductless chimneys. They must be cleaned regularly.
Hood overhang
Greater hood overhangs are suggested to help contain cooking fires in the hood area protected by the fire suppression system.
Noise levels
Loud kitchen hoods can affect well-being, and may even contribute to hearing loss. Variable speed fans are generally noisier at higher speeds and different models may have different noise levels. Vented hoods are generally noisier but more effective than recirculating hoods.
Noise levels are measured on dB(A) scale or in sones (in the U.S.). Most kitchen hoods produce 60-70 dB(A), while "quiet" models can go as low as 40 dB(A).
Flow
Hood air flow is measured in liters per second (L/s), cubic meters per second (m /s), or cubic feet per minute (cfm).
