Most residential building codes do not require a range hood above a stove or cook top, but you’d be wise to ensure your locale is not the exception. Even if it’s not legally required, you should think long and hard before forgoing a hood altogether.
Keeping this in consideration, are ductless range hoods worth it?
Unvented range hoods do filter some grease and cooking odors from the air, but the general consensus is that they’re nowhere near as effective. Nor do they remove heat and humidity, so they won’t help keep your kitchen cool while you cook.
Hereof, what happens if you don’t have a range hood?
1. Use a window fan. If you’re fortunate enough to have a window in your kitchen (or at least nearby), install a small window fan and run it on “exhaust” every time you cook. This will pull the air out, and while it may not do much for grease, it will help eliminate cooking odors.
Why do some kitchens not have a range hood?
Some kitchens have been designed and constructed on the cheap and may not have a range hood. This is more common in rentals and some older homes. It can be the scourge of the home with no way to exhaust airborne grease, smoke, cooking smells, and steam out of the kitchen.
