Converting a ducted range hood to a ductless system primarily involves installing a recirculating kit specifically designed for your range hood model. This kit allows the hood to filter air and return it into your kitchen, eliminating the need for external ductwork.
Understanding the Recirculating Kit
A recirculating kit is the essential component for converting a ducted range hood into a ductless one. It typically consists of:
- Charcoal Filters: These filters are crucial for trapping cooking odors, smoke, and grease particles from the air. Unlike ducted systems that expel these elements outside, ductless systems rely on these filters to clean the air before it's recirculated.
- Stainless Steel Vent (or Blower Vent): This component is installed on top of your range hood. Its purpose is to direct the filtered, clean air back into your kitchen space.
These components work together to ensure that while the air isn't vented outside, it is effectively cleaned and refreshed within the kitchen environment.
Steps for Conversion
The process of converting your range hood to ductless is generally straightforward, but it's crucial to follow your specific model's instructions.
- Check Compatibility: Before purchasing any kit, verify that your current range hood model is designed for conversion to a ductless system. Not all models are convertible, and compatibility often depends on the manufacturer and series.
- Purchase the Correct Recirculating Kit: Obtain the specific recirculating kit recommended by your range hood's manufacturer. Universal kits may not fit or function correctly.
- Install Charcoal Filters: Locate the filter housing within your range hood (often behind the grease filters). Install the new charcoal filters according to the kit's instructions. These are usually easy to snap into place.
- Install the Recirculating Vent: Attach the stainless steel vent or blower cover to the top of your range hood. This component typically connects to the hood's internal fan system, guiding the filtered air out through the vent openings.
- Remove or Seal Ductwork (if applicable): Since you're converting from ducted, you'll no longer need the external ductwork. You may choose to remove it completely or seal off the opening to prevent drafts and improve insulation.
Benefits of a Ductless System
Opting for a ductless range hood offers several advantages, especially in certain kitchen layouts:
- No External Ductwork Required: This is the primary benefit, making installation much simpler and more flexible, especially in apartments, condos, or kitchens where running ducts is difficult or impossible.
- Flexible Placement: Without the constraint of ductwork, you have more freedom to place the range hood wherever it best suits your kitchen design.
- Easier Installation: Generally, installing a ductless system is less complex and time-consuming than installing a ducted one, which requires cutting through walls or ceilings.
Considerations Before Converting
While converting to ductless offers convenience, it's important to be aware of certain aspects:
- Filter Maintenance: Ductless range hoods require regular replacement of their charcoal filters (typically every 3-6 months, depending on usage) to maintain effectiveness. Failing to do so will result in poor air purification and lingering odors.
- Humidity and Heat Removal: Ductless systems are highly effective at filtering grease and odors, but they do not remove heat or humidity from the kitchen. Since the air is recirculated, the temperature and moisture level in your kitchen will remain unchanged by the hood's operation.
- Airflow and Effectiveness: While significant improvements have been made in ductless technology, ducted systems generally offer superior performance in terms of overall air exchange and complete removal of all cooking byproducts.
Recirculating Kit Components
The table below summarizes the key parts of a typical recirculating kit:
| Component | Primary Function | Maintenance |
|---|---|---|
| Charcoal Filters | Absorb odors, smoke, and grease | Must be replaced periodically (3-6 months) |
| Stainless Steel Vent | Direct filtered air back into the kitchen | Occasional cleaning |
By understanding these points and ensuring your model's compatibility, converting your ducted range hood to a ductless system can be a practical and effective solution for your kitchen ventilation needs.
