What is a Microwave Exhaust Fan?

A microwave exhaust fan is an essential kitchen appliance for removing smoke, particles, and moisture from the cooking area. It typically functions as both a range hood, which serves to vent out smoke, steam, and odors from cooking activity, and acts as a built-in recirculating filter system that captures grease particles suspended in the air before they disperse throughout the home. 

The fan is typically mounted above the cooking surface and can be equipped with adjustable speed added ventilation options such as a boost or delay features.

Additionally, this kitchen appliance often features shock-resistant construction materials that won’t corrode over time with regular exposure to hot temperatures or moisture. All in all this convenient unit performs several tasks that keep the kitchen safe and odor free.

Benefits of Improving Your Microwave Exhaust Fan Efficiency

1. Improved Air Quality:

An efficient exhaust fan helps to reduce odors and pollutants in the kitchen by drawing them out of the room, ultimately leading to better air quality inside the home.

2. Lower Energy Costs:

By controlling humidity levels, an effective exhaust fan can help to reduce heating and cooling costs as it eliminates excess moisture from the air.

3. Reduced Mold Growth:

An effective exhaust fan helps to reduce the chances of mold growth, which can lead to potentially hazardous health effects.

Choosing The Right Microwave Exhaust Fan For Your Kitchen

Factors To Consider When Selecting a Microwave Exhaust Fan

1. Size:

This is one of the first and most important factors to consider when selecting an exhaust fan. It should be sized according to the size of your kitchen, with larger rooms requiring more powerful fans.

2. Noise Level:

The noise level produced by your exhaust fan will depend on the type of motor used in its construction. Make sure you select a fan that is quiet enough to not be disruptive in your home.

3. Energy Efficiency:

Look for an exhaust fan with a high energy efficiency rating as this will help you save money on electricity bills over time.

4. Warranty:

Make sure the exhaust fan you select comes with a good warranty, as this can provide peace of mind in case of any malfunctions.

Types of Microwave Exhaust Fans Available

1. Wall Mount:

Wall mount exhaust fans are typically the least expensive option and can be installed directly onto a wall in your kitchen. They are most suitable for kitchens with limited space and feature adjustable speed settings to suit different cooking needs.

2. Island Mount:

Island mount exhaust fans hang down from the ceiling and provide adequate ventilation for larger kitchens. They usually feature variable speed settings and can be equipped with a light fixture on top, adding to its practicality.

3. Under Cabinet Mount:

This type of exhaust fan is mounted beneath the kitchen cabinet, making it ideal for smaller kitchens or applications where space is limited. It offers adjustable speed settings and is typically quieter than other types of fans.

Tips For Improving Your Microwave Exhaust Fan Efficiency

1. Check and Clean the Filter Regularly:

Be sure to check and clean the filter regularly, as this will improve airflow efficiency and help keep your kitchen free from smoke, particles, and odors.

2. Select the Right Fan:

Select a fan that is sized according to your kitchen size, as this will ensure adequate ventilation and reduce energy costs over time.

3. Upgrade Your Ventilation System:

Upgrading from an older model to one of the newer more efficient models can make a big difference in reducing energy costs and keeping your kitchen free from pollutants.

4. Make Sure the Ductwork is Sufficiently Insulated:

Make sure that your ductwork is properly insulated, as this will help to keep the air temperature consistent and reduce energy loss.

5. Give Your Fan a Boost With a Motorized Damper:

A motorized damper will act as an additional boost for your fan, helping to improve efficiency and reduce energy costs.

6. Install a Humidity Sensor:

Installing a humidity sensor in your exhaust system will help to regulate the moisture levels in your kitchen, eliminating excess moisture that leads to mold growth.

Troubleshooting Common Issues with Microwave Exhaust Fans

1. Fan Won't Turn On:

If your fan won't turn on, check the power cords and outlets to make sure there is no loss of electricity. If the issue persists, you may need to replace the motor or contact a technician for further assistance.

2. Not Enough Air Flow:

If the air flow from your exhaust fan is not adequate, check the filter to make sure it is not clogged. If the filter is clean, you may need to switch to a higher-powered fan or upgrade your ventilation system.

3. Excessive Noise:

If your fan is producing too much noise, you may need to adjust the settings on the fan or switch to a quieter model. You can also try adding insulation to your ductwork to help reduce noise levels.

4. Fan is Leaking:

If your fan is leaking, check for cracks and seal any areas that may be causing the leak. If this does not resolve the issue, you may need to replace the fan's gasket or contact a technician for further assistance.


Choosing the right microwave exhaust fan is essential to keeping your kitchen smoke-free and energy efficient. Be sure to consider factors such as size, cost, energy efficiency rating, warranty, and installation method when making your selection.

Also keep in mind tips such as cleaning the filter regularly, selecting the right fan, upgrading your ventilation system, and giving your fan a boost with a motorized damper. With proper care and maintenance, you can ensure that your microwave exhaust fan is working optimally.
