    Why Trust Us?

    Everyone wants a kitchen that’s a welcoming, cozy place where people can gather, have a cup of coffee, and sit down for a nice chat. However, for this to be the case, you must ensure your kitchen environment is suitably set up. If your kitchen is one where the microwave seves as the kitchen ventilation, you will want to vent a microwave in your kitchen.

    Vented microwaves are essential solutions to any kitchen’s air quality needs, taking care of the challenges of airborne grease, odors, and smoke that cooking inevitably produces. Beyond their primary function of reheating or cooking, these microwaves integrate robust ventilation systems, offering a dual-purpose solution that optimizes both space and air quality. By expelling contaminants outside, they ensure a cleaner, fresher atmosphere, enhancing not only the cooking experience but also the overall health and comfort within the home. Learn more about how to improve kitchen air quality, including how to vent a microwave and which models we pick when it comes to purifying air in the kitchen.

    The Importance of Kitchen Ventilation

    Proper kitchen ventilation is crucial for maintaining a healthy indoor environment and can be easily attained through a kitchen ventilation fan. Having one helps to eliminate odors, smoke, and airborne grease, preventing the buildup of harmful pollutants in the air that can lead to respiratory issues. Effective ventilation removes excess heat, moisture, and carbon monoxide produced during cooking, reducing the risk of mold growth and promoting a more comfortable space.

    Health benefits include improved air quality, minimizing exposure to toxins, and preventing potential allergic reactions. Additionally, kitchen ventilation helps preserve the integrity of kitchen surfaces and cabinetry by reducing grease accumulation.

    Overall, buyers are more bound to come across a recirculating over the range microwave—which doesn’t expel air but rather filters it and redistributes it back—versus a ducted mode. However, there are microwave vent hood models available (at a higher cost), which are incredibly beneficial to the air quality in your home, especially if you have a gas cooking appliance. That’s because gas appliances work via a combustion process, which produces byproducts like carbon monoxide. Electric or induction cooktops produce less heat and emissions, hence requiring comparatively less ventilation power.

    Choosing an Over the Range Microwave for Your Kitchen

    Over the range microwaves combine multiple functions, serving as both a microwave and a ventilation system. Over the range ducted microwaves save countertop space, provide built-in lighting for the cooktop, and offer efficient kitchen ventilation by removing smoke and odors. Their integrated designs maximize kitchen utility and convenience in a compact, multifunctional unit.

    Thankfully, many brands have caught on to the need for over-the-range microwaves and offer some incredible options. GE over the range microwaves, Whirlpool over the range microwaves,

    LG over the range microwaves, and GE Profile over the range microwaves are all excellent brands on the market today. There are many other fantastic brands and models for sale as well, a variety of which we will highlight later on.

    Recirculating Microwaves vs Ducted Microwaves

    Recirculating microwaves utilize a filter to trap grease and odors before recirculating the air back into the kitchen, while over the range ducted microwaves vent outside, expelling the air pollutants. Recirculating units are easier to install as they don't require ductwork but are less effective in eliminating odors and moisture.

    On the other hand, ducted microwaves offer superior ventilation, effectively removing contaminants outdoors. Homeowners in apartments or spaces without access to exterior venting might prefer a microwave with vent fan for their ease of installation. In contrast, those seeking more efficient removal of cooking byproducts, particularly in larger kitchens, benefit from the superior air quality management from ducted microwaves.

    What is a Microwave CFM Rating?

    A microwave CFM (Cubic Feet per Minute) rating helps determine a microwave's ability to exchange air within a space. A microwave with a higher CFM rating is more adept at removing airborne pollutants and maintaining air quality. When selecting a microwave, consider the kitchen size and cooking habits to match the CFM rating to the ventilation needs. Larger kitchens or those with heavy cooking might require microwaves with higher CFM ratings for more effective air circulation and pollutant removal.

    As with range hoods, the general rule is 100 CFMs per every 10,000 BTUs of heat output. For example, a gas range with a total of 45,000 BTUs will need an over the range microwave with a ventilation system with at least 450 CFMs.

    How to Vent a Microwave

    Venting a microwave involves installing ductwork to channel air outside, which then expels cooking byproducts. Before venting an over the range microwave, check with the manual to be sure the model is suited for ducting; not all models are equipped for outdoor ducting, and trying to install ductwork can damage the appliance.

    With that in mind, the process is typically the same brand to brand. Here are some general steps.

    • Prepare the Space: Locate the mounting template provided with the microwave to mark where the vent will go. Ensure a clear path for the ductwork.
    • Drill Holes: Create openings for the vent and ductwork according to the template.
    • Install Ductwork: Connect the ductwork from the microwave to an external vent. This may involve cutting and fitting pieces to size.
    • Secure and Seal: Attach the microwave securely, ensuring a tight seal around the vent to prevent air leaks.

    While this can be a DIY task, complexities in installation and potential electrical or structural considerations make it advisable for a professional to handle. Professional installation ensures safety, compliance with local building codes, and proper functionality.
