Buying Guide for the Best 30 Inch Downdraft Gas Cooktops
What should you look for when you start buying your new downdraft gas cooktop? Are there some buying criteria that are better than others? This buying guide will highlight everything you need to know about this product so you can narrow down your choices and pick out the best one.
How Does a Downdraft Gas Cooktop Work?
Downdraft gas cooktops come with vents installed right into to the cooktop to efficiently pull fumes and smoke away from the area. It removes steam, grease, odor, and smoke through an exhaust fan in a downward motion. The smoke and smells go through several ducts before going outside.
Downdraft is a nice alternative to traditional under cabinet range hood vents. When you get a range hood vent, you have to have a lot of space when you install it, especially if you get a wall mount range hood.

It’s your job to put the exhaust together right in the cooktop. However, they can come with two different types of exhaust systems attached to them. We’ll outline them for you below.
- Active Downdraft Exhaust System – This is a system that you have to activate before it starts by pushing a button. You’ll find the vents at the rear of your stove with this type of exhaust. When you push the button, the fan will suck the steam, grease, and smoke through several ducts in a downward motion before expelling them outside.
- Central Downdraft Exhaust System – As the name implies, this exhaust utilizes a central system when it works. You’ll find it located in the center of your cooktop, and this is a stationary system. There are extractor fans located under the cooktop that pull air downwards before expelling it outside. No matter what you’re cooking, it’ll pull the steam, smoke, and smells away.
You’ll find that your downdraft gas cooktops vary wildly in their exhaust fan’s efficiency and strength. The rating for exhaust fans tells you how much air they can suck in once you switch them on, and this measurement is in cubic feet per minute. This is how much air your fan will suck in every minute, and the higher the number is, the more powerful your fan is. A CFM rating of 300 means that it’s powerful enough to remove the odors and smoke from stir-frying and searing food.
You want to get your product from a reputable brand. Going with a well-known brand is one way to help ensure they use quality materials and are available if you have questions, issues, or concerns. There are dozens of brands available, and this means there are hundreds of downdraft gas cooktops available. A few of the best brands include but are not limited too:
- General Electric
Exhaust Installation Process
Some of these cooktops require that you install an exhaust pipe that runs from the cabinet under the range outside. The exhaust pipes you have should be very straight and hard to ensure all of the fumes and smoke pull outside as efficiently as possible. A straight and hard exhaust pipe can also ensure that your fan runs quietly when it’s on.
Variable Fan Speeds
Many brands offer downdraft gas cooktops that have fans that run at a few different strengths. You can turn it on low, medium, or high, depending on what you’re cooking. If you notice that the fan is negatively impacting the burners and pulling the flames, having variable settings allow you to turn them on a lower setting to stop the interference. You’ll most likely notice interference only when you have the fan on the highest setting.
Filter Replacement Recommendations and Cleaning
There is a filter in this product that you have to clean every 6 to 12 months at a minimum. You can clean this filter by washing it with hot soapy water before rinsing it in clean water. Let it air dry before you return it to your cooktop. Some companies recommend that you replace this filter every five cleaning cycles, and this can be expensive. Don’t use your system without this filter.
Burner Strength and Numbers
Most cooktops come with four burners on them, but you can get products that have a fifth burner in the center of the cooking space. All of the burners usually have a different BTU rating, and this makes it easy to cook a broad range of food at the same time. Double-check the number of burners and the power rating to ensure it matches your needs.
