When it comes to kitchen appliances, few items command as much attention as the over-the-range microwave. This versatile gadget not only heats your leftovers but also serves as a space-saver and a range hood. However, one crucial question often arises: does an over-the-range microwave need to be vented? In this extensive article, we dig deep into this topic to help you make an informed decision for your kitchen.
Understanding Over-the-Range Microwaves
Over-the-range microwaves, commonly referred to as OTR microwaves, combine the functions of cooking and ventilation. Positioned above the kitchen range, these appliances are designed to free up counter space while providing an efficient method for cooking and removing smoke, steam, and odors generated during food preparation.
The Dual Purpose of an OTR Microwave
The dual functionality of over-the-range microwaves means they can either vent air outside or recirculate it back into the kitchen.
-
Vented Mode: In this mode, the microwave is connected to an external vent, allowing smoke and steam to exit your home. This method is generally more effective in eliminating unpleasant odors and airborne particles.
-
Recirculating Mode: In recirculating mode, the microwave uses a charcoal filter to clean and purify the air before returning it to the kitchen. This option is often easier to install since it doesn’t require ductwork but may be less efficient in controlling odors and smoke.
Why Venting Matters
Venting is not just a matter of preference; it is essential for maintaining a healthy cooking environment.
The Importance of Ventilation
Proper ventilation in the kitchen serves multiple purposes:
