Microwave Over the Range Venting Options Guide

Microwaves over the range (OTR) typically vent in two different ways, as outlined in our "Microwave Over the Range Venting Options Guide".

In the first example, the microwave over the range (OTR) will vent through the manufacturer installed grease or carbon filter, then directly through an exhaust port that is ducted to the outside of the structure. Typically there might be a cabinet installed over the microwave and inside that cabinet will be duct work or a soffit above the microwave, or a direct wall exhaust. Normally, this type of microwave over the range (OTR) will have a full frame door, with no panel above it, as depicted here.

In the second example below, the microwave over the range (OTR) will exhaust through the manufacturer installed grease or carbon filters, then recirculate the air back into the home. In many cases there are visible vents at the top of the microwave face frame, or a top panel that opens as a flap when the exhaust fan of the microwave is activated.

In either example, the cooking by-products are filtered through the filter medium, which is important. Capturing as much of the by-products as possible is the most crucial portion to any kitchen venting solution. Our mini hood/micro hood provides the additional capture zone necessary in order to complete your OTR microwave's exhaust function. Once the MICROVISOR® is installed, more effective containment is achieved, and improved updraft is accomplished. The positive effects of using MICROVISOR include reduced cooking product exposure throughout the home, less grease on cabinets and ceilings, reduced on-set of fire alarms, and better exhausting performance of your microwave over the range (OTR). During normal use with our hood you will see vast amounts of cooking grease that adhere to the bottom of the hood, that would normally escape into your home. Now, you can wash that grease down the sink! Microwave over the range owners who have recirculating models should install carbon based filters along with using the MICROVISOR. The carbon filters will neutralize the cooking odors that are circulating. Make sure to change them often for the best performance.
