Extractor hoods take the steam, smoke and grease particles from cooking and remove them from the air. Generally they work in one of two ways, either extracting air from the kitchen to the outside, or pumping it through a filter and recirculating it back into the kitchen. Extractors come in different sizes and styles. Mechanical extractor fans are fitted directly above the hob and draw air through ducting to the outside, helping to keep the kitchen free from clouds of steam. Canopy hoods are popular in modern kitchens where they can be placed discreetly into the bottom end of a wall cabinet. Chimney hoods are usually fixed against a wall and are an integral piece of furniture in the cooking area, drawing air up through a usually quite thick pipe and taking it outdoors. Integrated hoods are subtly hidden away inside a cabinet above the hob and only activated when opening the door. Here at Solmer we also stock air filters for kitchen cooker hoods.
