Cooking is one of life's great pleasures, but what about all those smells and fumes? The solutions used in the kitchen are the extraction hood, to expel air outside, or the filtering hood. However, as the extraction hood removes odors, it is also extracting warm air from the kitchen during winter and cool air during summer, thus pushing up heating and air-conditioning costs. The filtering hood using activated carbon filters has limited efficiency when it comes to removing odors and has significant maintenance costs since carbon filters require frequent replacement. But now there is a solution to all these issues in the shape of GALVAMET filtering hoods incorporating plasma technology.
