How Does Microwave Exhaust Work?
Understanding the working of microwave exhaust systems involves looking at the processes they use to ventilate and clean the air in your kitchen.
Step-by-Step Process of Microwave Exhaust Functionality
When you turn on your microwave’s fan during cooking, here is what typically happens:
1. Activation of the Exhaust Fan
Once your microwave oven is set to cook, the exhaust fan kicks into action, starting the process of drawing air into the system. This is initiated by either a manual setting or automatic sensors that detect high heat or smoke.
2. Air Intake
The fan pulls the warm, steamy air from around the cooking food into the microwave where the ventilation components are located.
3. Filtration Process
The air passes through the grease filter, which collects any grease particles. In a ductless system, it then moves on to the charcoal filter, which absorbs odors. The charcoal filter is crucial for ensuring that any smells are neutralized before the air is recirculated back into the kitchen.
4. Exhausting the Air
For ducted systems, the cleaned air is then expelled outside through the ductwork, effectively removing unwanted particles and moisture. Ductless systems return the cleaned air back into the kitchen, providing some relief but not completely eliminating contaminants.
Maintenance of Microwave Exhaust Systems
Regular maintenance is critical for ensuring the longevity and efficiency of your microwave exhaust system. Here are essential maintenance tasks:
1. Cleaning Grease Filters
Grease filters should be cleaned every couple of months or as needed. Most will be dishwasher safe, making maintenance a straightforward task.
