Re-activateOf all the options for kitchen ventilation, range hoods work best for venting smoke, fumes, and heat. Many good undercabinet range hoods and wall-chimney models (shown) often cost $800 or less; island models for venting cooktops often cost $2,000 or more.
Whether you buy a range hood or an over-the-range microwave oven, follow these steps to help it vent smoke and fumes effectively:
• Vent it to the outside, which helps vent as much smoke, cooking odor, and heat as possible.
• Use solid, smooth-walled metal ducting. Choose the largest size that fits your hood or microwave and inside the wall.
• Keep duct runs short and minimize curves. Both steps help maximize airflow.
• Prevent backdrafts by installing a wall or roof cap outside your home.
• Wash or replace the filters every one to three months, more frequently if you cook often.
