What type of duct is best for venting a range hood?
Range hoods must be vented using metal duct. Given a choice between flexible metal duct and smooth metal duct, go with the smooth. The ridges found in flexible metal duct create turbulence and will diminish airflow. * NEVER use 101.6mm dryer duct or any plastic duct on a range hood installation. The minimum size duct allowed on most range hoods is 82.55mm by 254mm which is equivalent to 152.4mm round. More powerful hoods require even larger duct sizes up to 254mm round. Consult the specifications for the model you have chosen. * When remodeling and changing hood and cooking equipment types do not reduce the ductwork size to less than the size specified for the range hood. Decreasing the duct size restricts the performance of the range hood ventilator. [Back To Top] • Which is better, ducted or non-ducted? Range hoods should be ducted to the outside of the home. While non-ducted filters trap some of the grease and odours from normal cooking, the humidity, smoke and heat will all be re c
Range hoods must be vented using metal duct. Given a choice between flexible metal duct and smooth metal duct, go with the smooth. The ridges found in flexible metal duct create turbulence and will diminish airflow. • NEVER use 4″ dryer duct or any plastic duct on a range hood installation. The minimum size duct allowed on most range hoods is 3 ” by 10″ which is equivalent to 6″ round. More powerful hoods require even larger duct sizes up to 10″ round. Consult the specifications for the model you have chosen. • When remodeling, changing hoods, or cooking equipment types, do not reduce the ductwork size to less than the size or specified for the range hood. Decreasing the duct size restricts the performance of the range hood ventilator.

Altering the product voids manufacturer’s warranty. Check for models that already offer remote switch options. What do the CFM and Sone ratings mean? CFM stands for Cubic Feet per Minute
