Range hoods do not have to be vented to the outside. But, ducted range hoods are almost always preferred over ductless hoods. They remove all the smoke and cooking exhaust from your kitchen, while ductless hoods recirculate your cooking exhaust back into your kitchen.

How do I know if my range hood is ducted?
The most obvious way to determine if your range hood is ductless is whether or not you have ductwork. If you have no ductwork, your hood recirculates kitchen air. Also, if your vent hood comes with carbon filters or a recirculating kit, it is ductless.
What is the point of a non vented range hood?
Ventless (Ductless) range hoods clear the air from the cooking fumes, grease, smoke, and odor by using a fan with charcoal filters. Unlike ducted models, these types of range hoods filter the air from odor and smoke and recirculate the clean air back into the kitchen.
Are recirculating hoods any good?
Yes. A recirculating range hood works beautifully, the same way as a ducted range hood. The main difference is that rather than the air getting exhausted to the outside, it passes through a filter, and then recirculated back into the house.
What is code for venting range hood?
In California, vent hoods are required that produce 100 cfm or more intermittently or produce 5 air exchanges in one hour. This is required in all residential areas, remodeled homes, or areas that are 1000 square feet or larger.
What is the difference between vented and non vented range hoods?
A vented hood, sometimes called a ducted hood, sends the grease, moisture, and air outside of your home through the wall or roof. An unvented hood filters the air through a carbon filter and recirculates the air inside your kitchen.
How do I know if my hood is vented?
Range hoods are vented up through the roof or out through an exterior wall. Look for a metal duct going through the cabinets above or an exhaust cap on the exterior wall behind the range hood. You should feel air being blown out of the exhaust cap on the roof or wall when the fan is running.
Do under cabinet range hoods vent outside?
Under-cabinet range hoods can be either ducted or ductless. Ducted range hoods vent air to the outside of your home while ductless hoods filter the contaminated air before circulating it back into your kitchen. This makes it easier to access your upper cabinets without any obstacles when the range hood is not in use.
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.
Do I need a hood over my stove?
Do I need a range hood for a gas stove? Yes. Gas stoves produce intense heat and smoke, so you need a kitchen fan that can vent heavy cooking exhaust outside your home. Buy a range hood that is at least 900 CFM to keep your kitchen air clean and fresh.
How do you vent a range hood on an outside wall?
Attach a wall or roof cap to the exterior wall or roof.
- Determine where you want to vent your range hood.
- Install your ductwork in the shortest unobstructed path to the outside of your home.
- Cut a hole 1-2 inches larger than your ductwork where you’ll run the duct from your hood.
- Attach the range hood to your ductwork.
Do ductless range hoods remove smoke?
Ductless range hoods use activated carbon filters, which filter out organic gases. Ductless range hoods will remove some of the smoke from the indoor air. But since smoke contains many different compounds as we discussed earlier, it will not remove all of the harmful chemicals and gases.
Does an extractor fan need to be on an outside wall?
Ducted extractors need access to an external wall so that air can be removed from the building via a pipe (or duct) to the outside. As a general rule, the shorter the duct run and the fewer the bends, the better your hood will perform.
Does a gas stove need to be vented outside?
Most gas ranges in the United States do not require venting to the outside. We recommend venting any gas range to the outside of your home. A professional-grade range hood will evacuate harmful cooking fumes, reduce cooking odors, and improve your health and safety.
Are exhaust fans required in kitchens?
An exhaust fan is required in a kitchen. A kitchen exhaust fan removes particles, smoke, carcinogens, and odors from your kitchen’s air. They prevent your house from filling up with cooking smoke and setting off alarms. Many local residential building codes require them.
Is it OK to vent range hood into attic?
No, you should never vent your range hood into the attic. The excess buildup of grease and moisture in your attic will ruin it and over time may cause mold damage. Instead, vent your hood through an interior wall or through the ceiling all the way outside of your home.
