Do Range Hoods Have To Be Vented Outside?
Yes, range hoods need to be vented outside in order to work properly and efficiently. The primary purpose of a range hood is to remove smoke, odors, and moisture from the air while cooking, and venting it outside ensures that it does not circulate back into the room. In addition to improving indoor air quality, venting outside also prevents potential fire hazards caused by the buildup of grease and other flammable substances. While recirculating range hoods are available and can be used as an alternative in certain situations, they are not as effective as vented range hoods.
