Even if the copper hood vent doesn’t vent to the outside, which is the optimal set up, it will still make a difference by just drawing away and dissipated the unhealthy are that comes from a stove that’s being cooked on. This is good news for many as it’s not always possible to vent to the exterior of the home.

Before settling on a particular copper hood vent, it’s important to consider some things.

Getting the Correct Size

Before running to the store or choosing a supplier for a copper hood vent, it’s important to measure the cooktop. The hood should cover the width of the burner area, and be mounted near the back to cover the rear burners as well. Believe it or not, there are many ill-installed copper hood vents.

As far as height, the blower intake should be over 2 feet above the cooktop. If the stove is gas-powered then one should figure the heating capacity in BTU in order to get a hood that offers the right amount of air flow to be useful and not just decorative.

Check Out the Features

The main features on a copper hood vent are the fan speed and the lighting levels if there is lighting featured on the hood. If there’s lighting, consider whether LED or halogen will be better. For some it doesn’t matter, for others they’d prefer it match existing lighting in the kitchen. A great feature on some vents is the ability to have it turn on when necessary and shut off on its own. Of course, it will be higher priced the more features it offers.


The blowers on copper hood vents rate by cubic feet of the air they are able to effectively clean in a minute’s time. This is called CFM. The higher the rating, the more airflow it can handle. As the old adage says, bigger is better. Prices will go up but it will be well worth the investment. Electric cook tops can have a range hood rated in CFM, but gas cooktops should be rated by BTU of the range, and then CFM of the hood. Of course, a great source is a salesperson or the manufacturer/builder of the choice copper hood vent.


Noise is another important factor when choosing a copper hood vent. A very loud vent can be annoying, leading the owner to not use it as often. Then this defeats the whole purpose of having one! While it may look nice, what’s the point if it doesn’t perform well. The higher the sones a hood vent has, the louder it will be. 1 sone is about the sound a refrigerator makes, to give an idea. Higher priced models carry less sones, and motors that are better built overall, this is because they use the latest technologies.


Grease building up is never a good sign. It may be time to change the filter on the copper hood vent. No one wants to spend time scrubbing walls and appliances. This is more common with air that recirculates rather than those that vent to outside. Still, look for types that have carbon filters that are simple to replace.

While a recirculation type of copper hood vent is cheaper to install, those savings may not be worth it in the long run. Taking into account the amount of ventilation needed is key. Either way, the copper addition will bring a beauty unlike any other to a kitchen.
