Step1
Read product reviews. These reviews are becoming more common on the web. People who are not invested in any company will write reviews for products. Take them with a grain of salt, but spend a little time reading them.
Step2
Look up the manufacturer's recommendation for the fan that works best with your stove. If you are replacing an existing fan, then make sure the new fan fits in the location without much adjustment. If you have a hood, then you will need to use a fan specified for that use.
Step3
Talk to friends and acquaintances. You may be surprised at who knows more about exhaust fans than you would expect. When you bring up your need in conversation, inevitably someone knows where you can get a deal or tells about a recent experience buying a new fan.
Step4
Shop online once you have determined which model that you need. A number of websites for appliances have good contacts for best prices. Some website suggestions are listed below.
