Ducted range hoods are more effective at removing smoke, heat, and odors.
- Ductless hoods recirculate air and require regular charcoal filter replacements.
- Choose ductless when ducting is impossible, but expect lower performance.
- Consider installation cost, filter upkeep, and your cooking style when deciding.
How does a ductless range hood work?
Ductless range hoods, also called recirculating hoods, pull air through a grease filter and then a charcoal filter. The charcoal filter traps odors before the air is released back into the kitchen. This process does not remove heat or humidity. It also cannot vent smoke as effectively as outdoor venting. According to the EPA, recirculating systems are less efficient at removing indoor air pollutants.
What are the key differences between ducted and ductless hoods?
Ducted hoods capture cooking emissions and expel them outside through ductwork. Ductless hoods filter and recirculate the air. Ducted systems remove heat, moisture, and odors completely. Ductless systems only reduce odors and some grease. Airflow is measured in cubic feet per minute (CFM). Ducted hoods typically have higher CFM ratings, often 400 to 600 CFM or more. Ductless hoods usually have lower CFM, around 200 to 400 CFM, because they push air through filters.
Which type is best for your kitchen?
Choose a ducted hood if you cook frequently with high heat, such as frying or searing. It is also better for open kitchens where odors linger. Ductless hoods work well for small kitchens, apartments, or homes where exterior venting is not possible. They are easier to install and cost less upfront. However, you must replace charcoal filters every 3 to 6 months. Consider your cooking style and kitchen layout before deciding.
Can you convert a ducted hood to ductless?
Yes, many ducted hoods can be converted to ductless by adding a charcoal filter kit. The kit typically includes a charcoal filter and a diverter to redirect airflow. Check the manufacturer's instructions for compatibility. Some hoods are designed for both venting options. Conversion is useful when you move to a home without ductwork. But remember, performance will drop to ductless levels.
What are the installation and cost considerations?
Ducted hoods require ductwork, which can be complex and costly to install. Ductless hoods are simpler and cheaper to install, often a DIY project. Ducted systems may require professional installation, especially if you need new ducts. Ductless hoods have lower upfront costs but ongoing filter expenses. Over time, filter replacements can add up. Compare the total cost of ownership, not just the purchase price.
