When installing a ducted venting system, it is essential to ensure that your kitchen layout allows for the installation of ductwork leading to the outside. Additionally, the distance from the microwave to the vent should be within the manufacturer’s specifications to maximize performance.
2. Non-Ducted Venting (Recirculating)
In contrast to ducted venting, non-ducted venting, also known as recirculating, does not expel air outside. Instead, it filters the air through charcoal filters and recirculates it back into the kitchen.
Advantages of Non-Ducted Venting
- Flexible Installation: This method does not require ductwork, making it suitable for apartments or homes where external venting is not feasible.
- Less Costly Installation: Since non-ducted systems do not need extensive ductwork, they can be more economical to install.
Drawbacks of Non-Ducted Venting
While non-ducted venting has its benefits, it does come with limitations:
- Less Efficient: Non-ducted systems are generally less effective in removing pollutants from the kitchen.
- Filter Maintenance: The charcoal filters need to be replaced regularly to maintain efficiency, which can be an added expense over time.
Understanding Ventilation Performance Ratings
When evaluating ventilation performance, it’s essential to consider the CFM (Cubic Feet per Minute) rating. The CFM rating indicates how much air can be moved or exhausted per minute through the venting system.
Recommended CFM Rating for Kitchens
- Cooking on low heat typically requires a CFM rating of about 100-200.
- Medium cooking necessitates a CFM range of around 200-350.
- High-heat cooking (e.g., frying or grilling) recommends a CFM rating over 350 to adequately remove smoke and odors.
