Can You Increase Range Hood CFM?


An effective range hood is essential for keeping a kitchen atmosphere that is both clean and healthful. It aids in the removal of contaminants including smoke, oil, smells, and others created while cooking. However, if you discover that the CFM (Cubic Feet per Minute) of your present range hood is not delivering the appropriate performance,

you might question whether there are any ways to boost its strength. This post will examine various techniques for raising the CFM of your range hood and improving its functionality. These suggestions will enable you to get the most out of your kitchen ventilation system regardless of whether you own a Winflo range hood or another kind.
Can You Increase Range Hood CFM?
Regularly cleaning the filters is one of the simplest methods to increase the CFM of your range hood. Grease and dirt can build up on the filters over time and block airflow. For details on how to remove and clean the filters, consult the user handbook that came with your range hood.

Depending on the filter type, they may often be cleaned in a dishwasher or with warm, soapy water. Prior to reinstalling them, make sure they are totally dry.

The best performance from your range hood is ensured by routine filter cleaning. Better airflow increases CFM and the ventilation system’s overall efficacy thanks to clean filters. Additionally, clean filters avoid the buildup of oil and other debris, which lowers the danger of fires and increases the lifespan of your range hood.

Clean the Blower

 Another essential component that requires routine upkeep is the blower. It is in charge of removing air from inside the range hood and releasing it outdoors. On the blower blades, dust, oil, and grime can assemble and reduce efficiency.

Remove any panels or filters that may be covering the blower, then turn the power off. To carefully clean the blades and get rid of any dirt, use a soft brush or a moist cloth. Before putting the blower back together, make sure it is thoroughly dry.

Airflow through the range hood is ensured to be unrestricted by a clean blower, increasing CFM. You may avoid blockages and keep your range hood operating efficiently by routinely cleaning the blower. A clean blower also aids in lowering noise levels and enhancing the ventilation system’s overall effectiveness.

7 Tips for Better Power with Your Winflo Range Hood

Remove Blockages in the Ductwork:

Your range hood’s CFM may be greatly impacted by blocked or obstructed ductwork. Check the ductwork to make sure there are no airflow-restricting obstacles like bird nests, dirt, or bends. Clean or fix any obstructions you uncover as necessary. In addition,

make sure the ductwork is correctly sealed to minimize air leakage, since this might reduce the ventilation system’s efficacy.

The CFM of your range hood may be increased thanks to smooth airflow through clean, unblocked ducting. Regular ductwork inspection and cleaning assures peak efficiency and averts any possible problems that can impair your range hood’s efficacy.

Keep the Range Hood Fan going After Cooking:

It’s a good idea to keep the range hood fan going for an extra 10 to 15 minutes after you’ve finished cooking. This makes it possible for the hood to get rid of any leftover smoke, aromas, or dampness in the kitchen. Additionally, by avoiding the buildup of oil and other particles,

leaving the fan on for a short while after cooking contributes to maintaining a cleaner atmosphere.

After cooking, keeping the fan running improves ventilation and raises the CFM of your range hood. It makes sure that any lingering smoke, aromas, or wetness are efficiently removed, fostering a clean and fresh kitchen atmosphere. By avoiding grease buildup and extending the lifespan of the range hood, this approach also lessens the strain on it.

Purchase a range hood with a sufficient CFM:

Consider switching to a model with a greater CFM if your existing range hood isn’t providing enough ventilation for your requirements. The range hood’s CFM rating defines how much air it can circulate in a minute. It’s important to choose a range hood that fits your kitchen’s size and level of cooking activity. In order to efficiently eliminate smoke and smells, range hoods with greater CFM ratings are often needed in larger kitchens or those with high-output cooktops.

A higher CFM range hood will guarantee that your kitchen has enough airflow. A range hood with a greater CFM rating can flow more air, which improves its ability to remove smells, oil, and smoke. When selecting a range hood with the proper CFM rating, take into account the size and configuration of your kitchen as well as the sort of cooking you perform.

Purchase a Range Hood with a Multi-Speed Fan:

You can modify the airflow to suit your cooking needs with a range hood that has different fan settings. The ability to boost the fan speed when cooking with high heat or pungent aromas can improve the range hood’s overall performance. 

Lower fan speeds can also contribute to a quieter cooking atmosphere in the kitchen.

Selecting a range hood with different fan settings offers superior CFM control and enables you to tailor the ventilation to meet your unique demands. While lower fan speeds are adequate for daily cooking, higher fan speeds may swiftly eliminate smoke and strong smells.

It helps your kitchen run more efficiently and with better power when you can change the fan speed.

Select a Range Hood That Ducts Outside:

Range hoods that vent outside are frequently more successful in removing pollutants than recirculating hoods. You might want to think about converting to a range hood with an exterior vent if the one in your kitchen presently circulates air.

You can avoid moisture, smells, and smoke from your kitchen from being sucked back into the room by venting the air outdoors.

Better airflow and more CFM are both provided by ducting your range hood to the outside. Ventilating the air outside stops contaminants from being recirculated, creating a cleaner, fresher kitchen atmosphere. When installing your range hood, take into account if ducting is possible. If necessary, get expert assistance.

Be on the lookout for range hoods with a low sone rating in relation to CFM:

A range hood’s sone rating gauges the amount of noise production. High CFM is necessary for performance, however it frequently leads to more noise. Choosing range hoods with a low sone rating in relation to their CFM will help you create a balance between power and noise. This enables effective ventilation without causing your kitchen undue noise disruption.

You can be sure that the ventilation will be efficient without being overly noisy if you use a range hood with a low sound rating. In order to get optimum performance without compromising your kitchen’s comfort, use equipment with a balance between CFM and sone rating.

If you want more power than a standard range hood can provide, think about purchasing a range hood that is compatible with a remote blower. A remote blower, an independent device, can be put in a remote location, such an attic or an outside wall. These blowers may significantly enhance the performance of your range hood because they have higher CFM ratings.

Your possibilities for reaching larger CFM ratings increase if you choose a range hood with a remote blower. Greater power and efficiency may be achieved with remote blowers, particularly in bigger kitchens or for individuals who need additional ventilation as a result of intensive cooking. Because it is situated further from the range hood,

the remote blower unit is quieter and has additional positioning possibilities. With this configuration, your range hood’s CFM is maximized and optimal ventilation performance is guaranteed.

Right Mounting Height:

For optimum performance, your range hood must be mounted at the right height. Between 28 and 36 inches is the appropriate space between the cooktop and the bottom of the hood. As a result, the hood is better able to contain cooking gases and keep them from leaking into the kitchen. The effectiveness of the range hood might be lowered by mounting it either too high or too low.

Your range hood will function at its best if it is mounted properly. You may help the hood properly collect and eliminate smoke, oil, and aromas from your cooking area by sticking to the suggested installation height. This encourages improved airflow and raises the range hood’s total CFM.


Maintaining a clean and healthy kitchen environment depends on your range hood operating effectively. No matter if your range hood is a Winflo model or not, you may increase its CFM and overall performance by using the aforementioned advice. Simple maintenance procedures may have a big impact, such routinely cleaning the filters and blower, clearing blockages from the ducting, and leaving the fan on after cooking. If more space is required, think about switching to a range hood with a larger CFM,

different fan settings, and support for a remote blower. You may increase the strength and efficiency of your range hood by using these techniques, resulting in a clean and enjoyable cooking environment.
