Top 9 Best External Venting Microwave, Our Picks

When considering purchasing an external venting microwave, several key factors can significantly impact your decision. Understanding these factors will help you choose a model that best fits your needs and kitchen setup.

1. Kitchen Ventilation Setup: Before buying an external venting microwave, assess your kitchen's current ventilation setup. External venting microwaves require an exhaust duct that leads outside the house. If your kitchen doesn't already have such a duct, installation can be costly and may require professional assistance. Alternatively, consider models with recirculating vents if external venting is not feasible.

2. Ventilation Power and Efficiency: The effectiveness of an external venting microwave depends on its ventilation power and efficiency. Look for microwaves with high CFM (cubic feet per minute) ratings, which indicate how much air the venting system can move. Higher CFM ratings are generally more effective at removing smoke, steam, and odors from your kitchen.

3. Size and Placement: Consider the size and placement of the microwave in relation to your stove or cooktop. Ideally, the microwave should be installed directly above the cooking area for optimal venting efficiency. Measure the space available in your kitchen to ensure the microwave fits comfortably and that there is adequate clearance for venting.

4. Noise Levels: External venting microwaves can produce varying levels of noise depending on their ventilation system and fan speed. Consider models that offer multiple fan speeds so you can adjust the ventilation power according to your cooking needs. Quieter operation may be preferable, especially in open-plan kitchens or homes where noise sensitivity is a concern.

5. Features and Design: Beyond ventilation capabilities, consider additional features that enhance usability and convenience. Look for intuitive control panels, preset cooking programs, and easy-to-clean surfaces. The design should complement your kitchen decor and provide functional benefits such as sensor cooking technology or convection heating options.

6. Energy Efficiency: Check the energy efficiency ratings of the microwave model you're considering. Energy-efficient appliances not only save you money on utility bills but also reduce your environmental footprint. Look for microwaves with Energy Star certification, indicating they meet stringent energy efficiency guidelines set by the Environmental Protection Agency (EPA).

7. Installation and Maintenance: Finally, factor in installation requirements and ongoing maintenance. External venting microwaves may require professional installation, especially if ductwork needs to be installed or modified. Ensure you understand the warranty terms and recommended maintenance practices to keep your microwave running efficiently for years to come.

By considering these factors before purchasing an external venting microwave, you can make a well-informed decision that aligns with your kitchen's needs and enhances your cooking experience.

Whether you should vent your microwave outside depends on several factors such as your kitchen layout, local building codes, and personal preferences. Venting your microwave outside is recommended if:

• You frequently perform heavy cooking tasks that generate a lot of steam, smoke, or odors.
• Your microwave is installed over a range or cooktop, where cooking fumes are more concentrated.
• You want to maintain better indoor air quality by expelling pollutants and excess moisture outdoors.
• Your local building codes require external venting for microwaves installed in certain configurations.

Do countertop microwaves need to be vented?

Countertop microwaves typically do not require venting because they are designed to sit on countertops and do not have built-in ventilation systems like over-the-range microwaves. However, it's essential to ensure that there is sufficient space around the microwave to allow for proper air circulation and prevent overheating.

Does a built-in microwave have to be vented?

Built-in microwaves, especially those installed over a range or cooktop, often have the option for venting to the outside. While it's not always mandatory, venting a built-in microwave outside is recommended, especially if it is used for heavy cooking tasks or if local building codes require it for safety and air quality reasons.

Do convection microwaves need to be vented?

Convection microwaves, which combine microwave technology with convection cooking, may benefit from venting to help dissipate heat generated during the convection cooking process. While it's not always required, venting a convection microwave can help prevent overheating and maintain a comfortable kitchen environment, especially during extended cooking times.

What happens if you don't vent a microwave?

If you don't vent a microwave, cooking odors, steam, and smoke can accumulate in the kitchen, leading to poor indoor air quality and potential health hazards. Additionally, without proper ventilation, moisture from cooking can condense on surfaces, leading to mold and mildew growth. Venting a microwave helps expel pollutants and excess moisture outdoors, maintaining a healthier and more comfortable kitchen environment.
