This extractor hood is designed to keep open kitchens smoke and odor-free. It solves the three most common problems in the kitchen: smoke, odors, and air pollution from cooking oil. It eliminates smoke produced by hot oil 17,000 times more efficiently than regular hoods! The hood's powerful patented cyclone technology sucks up fumes and harmful particles produced by frying and eliminates the carcinogens released by fumes from hot cooking oils. That brings relief to people who suffer from respiratory illnesses and allergies, the elderly, and pregnant women.
