Recirculating hood: odors not removed / charcoal filter

Ductless hoods rely on charcoal filters that cannot be washed and lose effect over time. Grease filters must be clean or the charcoal clogs fast. Replace charcoal on the maker's schedule.

Range hood ducting: duct size, route, termination and makeup air

Hood performance depends more on the duct than the blower. Use the duct size the hood requires (never smaller), smooth metal duct, as few elbows as possible, and a proper wall or roof cap with a damper. Larger hoods can trigger a makeup-air requirement under local code (commonly when the hood can exhaust more than 400 CFM in homes with certain fuel-burning appliances).

Range hood turns on by itself or jumps to high speed

Many hoods (e.g. Broan Heat Sentry and similar) have a heat sensor that starts the fan or raises speed when it senses excess heat. That is a safety feature, not a fault. If it runs with a cold cooktop, suspect the sensor, a stuck switch or the control.
