Quick Guide

A kitchen downdraft fan is a ventilation system built into the cooktop or countertop. Instead of pulling smoke upward, a downdraft range hood pulls air down through a cooktop downdraft vent. This type of downdraft ventilation is popular in modern kitchens where a clean, open design is important.

Why People Choose a Downdraft System

• Ideal for island or peninsula cooktops
• Keeps the kitchen layout open and minimal
• Useful when overhead venting is difficult
• Works well for light to medium cooking

How a Downdraft Fan Works

The fan pulls steam and smoke downward through hidden ducting and vents it outside. It’s a compact alternative to traditional hoods and often considered one of the best downdraft system options for kitchens with limited space.

What to Look For

• CFM: Most kitchens need between 300–600 CFM
• Duct Size: Larger ducts improve airflow and reduce noise
• Noise: Look for quieter models if the kitchen is open-concept
• Cooktop Type: Gas cooktops may need higher airflow

Downdraft vs Traditional Hood

Downdraft fans offer a clean look and save space. Traditional hoods still provide stronger capture for heavy cooking, but downdrafts are a great option for island setups or kitchens with low ceilings.
