This article delves into what recirculating venting is, how it works, its benefits, and considerations for choosing a microwave with this type of system.
What is Recirculating Venting?
Recirculating venting, often referred to as ductless or internal venting, is a method utilized in certain microwaves to manage air circulation within the kitchen. Instead of venting air outside through ducts, the air is filtered and returned to the kitchen space. This type of ventilation is especially common in microwave range hoods and built-in microwaves where external venting is impractical or impossible due to structural constraints.
How Does Recirculating Venting Work?
To better understand recirculating venting, it’s essential to know the process involved. Here’s a step-by-step breakdown:
1. Air Collection
When the microwave operates, it generates heat and steam from the cooking food. The recirculating venting system features a motorized fan that draws in the warm air, smoke, and steam from the cooking area.
2. Filtration Process
Once collected, the air passes through one or more filters. The purpose of these filters is twofold:
- Grease Filtration: This typically involves a metallic mesh filter that captures grease particles to prevent them from settling onto surfaces and contaminating food.
- Odor Filtration: Many systems also incorporate charcoal filters, which are designed to absorb and neutralize odors, ensuring the air returned to your kitchen is fresh.
3. Air Reintroduction
After passing through the filters, the now-cleaned air is released back into the kitchen, improving the overall air quality while cooking.
Benefits of Recirculating Venting

What is recirculating venting in microwaves?
Recirculating venting in microwaves is a method of ventilation that filters and circulates air back into the kitchen instead of venting it outside. This system utilizes charcoal filters to trap smoke, grease, and odors produced during cooking, ensuring that the air released back into the environment is cleaner and healthier. It is particularly beneficial for homes without external venting options.
This type of venting is commonly found in over-the-range microwaves, which not only serve as cooking appliances but also double as range hoods. When the microwave operates in recirculation mode, air is drawn through the filters, cleaned, and then returned to the kitchen, making it an efficient solution for smaller spaces where exhaust venting isn’t feasible.
How does recirculating venting work?
Recirculating venting works by pulling in the air from the cooking area through an intake vent, typically located at the bottom or front of the microwave. Once the air is drawn in, it passes through a series of filters, primarily charcoal filters, designed to trap odors and grease. The filtered air is then released back into the kitchen environment through an exhaust grill, ensuring that any unpleasant smells or particles are effectively mitigated.
While no outdoor venting occurs, it is essential to regularly replace or clean the filters for optimal performance. Most manufacturers recommend changing charcoal filters every six months, depending on usage. This maintenance is crucial to keep the appliance functioning correctly and to maintain air quality in the kitchen.
