Safety should always be your top priority. Poor ventilation can lead to safety hazards in your kitchen. And it can easily become a breeding ground for contaminants, such as grease, smoke, or other substances. But air quality should not be your only concern. Grease fires are also possible. These can prove to be very dangerous for your family if they are not addressed promptly. 

But can a range hood reduce the likelihood of a grease fire? In this post, we will discuss what a range hood is, how it works and how it can be used to prevent a grease fire in your kitchen.  

What is a Range Hood?

Range hoods are an essential part of every kitchen. They remove odors, smoke, and other harmful particles from the air that you inhale while you cook. The powerful fans pull the air around the stovetop through filters and into a duct for exhaust. To prevent food contamination, smoke, heat, moisture, microscopic food particles, and other impurities are removed from the kitchen.

The range hood prevents grease, smoke, and other unwanted contaminants from building up inside your kitchen. The range hood vents these contaminants to the outside of your house so that you can have clean, fresh kitchen air. 

No matter what cooking style you prefer, we recommend that every kitchen have a range hood. For those who love to cook or do a lot of frying and grilling, it is even more essential. Everyone can benefit from improved air quality and fewer cooking smells. 

A range hood can greatly reduce the chance of a grease fire in your kitchen because range hoods clean the air of oil smoke and grease while you cook. This greatly reduces the chances of fire.
