Size – Outdoor Vent Hood Sizing Guide

Size is a great matter of regret for the outdoor kitchen vent hood. We recommend at least 12 inches larger hood considering your range. Extra-large 12 inches will be enough to cover the lower range properly in both directions. As a result, it increases the performance of smoke and grease capturing.

For example, a 24″ range needs a 36″ outdoor vent hood and a 36″ range needs to vent with a 48″ vent hood.

CFM – How many CFM do I Need for An Outdoor Grill?

You should look at the vent hood’s CFM. As it is an outdoor range hood it should be more powerful to do its job in an open environment.

Generally, we recommend a range hood with a CFM of 1200 for outdoor kitchens since it has to deal with the wind of air and the amount of smoke produced by the grill. Besides, you can calculate how much your grill machine requires CFM. Suppose, the total BTUs of your grill is 90,000. Simply 90,000 divided by 100 which means you need a 900 CFM outdoor vent hood.


Since it’s an outdoor appliance, it’s going to get very dirty, making stainless steel range hoods more convenient to clean. A vent hood should be cleaned after every 24 hours of use to prevent dripping grease and dirt build-up. To make the task easier you should go for a stainless-steel outdoor vent hood.


In terms of the outdoor kitchen, we suggest baffle filters. Because baffle filters are more efficient than mesh filters. In contrast, baffle filters can be cleaned very easily with a dishwasher. A baffle filter is very strong to catch the maximum amount of grease to prevent build-ups.
