Excerpt from Range Hood Size Calculator - How to Choose The Correct Size of Range Hood :
Range Hood Size Calculator - Common sense dictates that the more heat a unit produces, the more airflow will be required to rid the greater amount of resulting grease and smoke. Let's call this the Common Sense Rule. That said, the first calculation method we will look at is based on cooking surface size and range hood location. If the hood is mounted on a wall behind the range (as most are), then you will use the 40 cfm per linear foot of cooking surface rule. This method dictates that for a typical 30" four burner range, you should employ at a minimum a hood able to move 100 cfm's of air. But remember the Common Sense Rule. If you do a lot of frying or wok cooking and therefore produce an increased level of grease and smoke, you will likely be disappointed with a 100 cfm unit - go bigger. To extend this method to kitchen island cooking, the 50 cfm per linear foot of cooking surface rule should be used. With the same 30" four burner range operating in an island, the minimum cfm's are bumped up to 125, and as always, the Common Sense Rule is applied.
Range Hood Size Calculator - By applying either of these two methods in combination with the Common Sense Rule you can be well on your way to ensuring that your home remains a clean, healthy and inviting place to be.
