The best range hood for a gas stove is a ducted (vented-outdoors) hood with enough CFM to match your burners' total BTUs and the static pressure to clear the duct—because a gas flame adds combustion gases like NO2 and CO to the usual grease and fine particles, and only venting outside fully removes them. This guide explains the gas-specific specs that matter, shows the simple BTU-to-CFM math, and compares ROBAM's top range hoods for gas ranges across sizes and kitchens. More
