If you’ve recently purchased an over-the-range (OTR) microwave, you might have noticed features that set them apart from traditional microwaves. One of the most significant differences is how they vent. Understanding how over-range microwaves vent is essential not only for your cooking experience but also for maintaining an efficient kitchen environment. This article will delve into the intricate workings of OTR microwaves, how they effectively manage air quality, and the various venting types you may find.
What is an Over-Range Microwave?
Over-range microwaves serve a dual purpose: they act as a traditional microwave oven while also functioning as a range hood above your stove. This two-in-one unit cleverly maximizes kitchen space, particularly in smaller kitchens where counter space is at a premium. But beyond convenience, these appliances help to keep your cooking area smoke-free and odor-free by venting hot air, steam, and cooking odors outside or recirculating them back into the kitchen.
How Do Over-Range Microwaves Vent?
Understanding how OTR microwaves vent involves knowing the types of venting systems available. Primarily, over-range microwaves vent via two methods: external venting and recirculating venting.
1. External Venting
External venting is often regarded as the most effective method for removing airborne particulates from your kitchen. Here’s how it works:
Mechanism of External Venting:
– The microwave draws in air from the cooking area through its grease filters located at the bottom.
– This air is then passed through a fan system that drives it out of the kitchen through ductwork installed during the microwave installation.
Pros of External Venting:
– Superior Odor Control: By exhausting air outside, external venting significantly reduces cooking odors and smoke.
– Better Air Quality: Removes heat and humidity during cooking, which can help maintain a comfortable kitchen environment.
Cons of External Venting:
– Installation Complexity: External venting requires proper ductwork, which may increase installation costs and complexity, especially in kitchens that are not pre-equipped for it.
– Space Constraints: The ductwork must be routed outside, which may be challenging in densely packed kitchen layouts.
2. Recirculating Venting
Recirculating venting is designed for spaces where external venting isn’t feasible. It reuses the air in the kitchen, making it an adaptable option for many homes.
Mechanism of Recirculating Venting:
– Similar to external venting, air is drawn through the grease filters but is instead cleaned and circulated back into the kitchen.
– The microwave’s charcoal filters help absorb odors, allowing cleaner air to re-enter the cooking space.
Pros of Recirculating Venting:
– Simplified Installation: No ducting is required, making it easier and cheaper to set up.
– Flexibility: Suitable for apartments or homes where external venting isn’t an option.
Cons of Recirculating Venting:
– Limited Efficiency: Because air is recirculated rather than expelled, it may not eliminate odors and humidity as effectively.
– Filter Maintenance: The charcoal filters need to be changed regularly to maintain efficiency, which adds to ongoing maintenance.
Critical Components of Over-Range Microwave Venting
Several essential components work to ensure that over-range microwaves vent efficiently. Understanding these parts can help you better appreciate their functionality.
1. Grease Filters
Grease filters trap and remove grease particles from the air. They are typically made from metal or charcoal, depending on whether the unit uses external venting or recirculating methods. Regular cleaning and maintenance of these filters are crucial for optimal performance.
2. Fan or Blower
The fan, often referred to as a blower, is integral to either venting method. It pulls air into the microwave’s ventilation system, ensuring that cooking smoke and odors are either expelled or treated before being sent back into the kitchen.
3. Charcoal Filters
For recirculating venting systems, charcoal filters are a necessary component. They absorb odors and improve air quality. These filters must be replaced periodically to maintain effectiveness.
Choosing the Right Venting Option for Your Kitchen
When deciding between external venting and recirculating venting for your over-range microwave, several factors must be considered.
