When it comes to searching for the best wall vent cap for a range hood, you need to be cautious and know exactly what you want. A range hood is perfect for someone who cooks on a high-powered stove. Most homes have heating and air AC systems with ductwork connecting the furnace to the different rooms. 

Wall vent caps help to cover the wall opening where the ducts come into the room. Dampers are normally attached to the back of airflow into a room. It is common to find wall vent caps for range hoods in many homes with forced air systems. But, what is the best wall vent cap for a range hood to buy today? Below we’ll review some of the best options to consider buying.

What Type of Duct Is Best for Venting a Range Hood?

The best type of duct for venting a range hood depends on the design of your kitchen. If you have the option of choosing a flexible metal and a smooth-wall air duct, you can select the second option. The reason this is advisable is that the ridges in the flexible metal ducts tend to create turbulence, which may end up reducing the airflow.

Below are some of the types of duct suitable for venting a range hood.

  • Semi-rigid duct – The good thing about this is that it’s flexible, high-quality, and durable.
  • Rigid duct – It offers higher quality than flex duct and it’s also made of durable material.

How Do I Choose a Hood Vent?

When it comes to choosing a hood vent, there are several things you need to consider. They include:

Standard Improvement for Your Home in Your Area

The standard improvement your home needs depending on your area is the first you need to consider before choosing any hood vent. There is the option of choosing ducted or non-ducted hood vents. Therefore, you have to compare these two options before making your decision.

Budget

Although it sounds like a common question, the cost is also a major contributing factor when choosing a hood vent. You have to consider your budget and the hood vents available in that price range to determine whether they are worth it or not.

The Type of Vent

The type of vent also plays a significant role in your decision – since you wouldn’t want to choose a hood vent that won’t fit perfectly with your home vent system. Therefore, you need to check on this factor to ensure you select the right hood vent.

Hoods should be designed in regards to the size and strength of the range. Therefore, a hood that is properly designed should cover the full width of the range and at least 50 percent of the front burners. 

Pro Tip: The strength of a vent hood is determined by the amount of air it moves, which is represented in CFM (cubic feet per minute).

How Many CFM for a Range Hood Do I Really Need?

Since the ventilation power of your range hood is measured in cubic feet per minute (CFM), that means the higher the CFM the more air the hood can vent out of your kitchen. To be able to properly power a vent hood, you need to have at least 100 CFM for every 10,000 BTUs of your stovetop. 

Here’s a good example:

200,000 CFM requires at least a 2000 CFM range hood. In the case of electric stoves, you can multiply the width by 10. 

If you want to efficiently vent the cooking exhaust from your kitchen, consider using a range hood of at least 600 CFM.

The best range hood is typically different for each person since it depends on your cooking style and kitchen habits.
