Nova Curved Filter Detachable PVC Oil Cup Kitchen Chimneys are kitchen appliances designed to remove the odours, steam, smoke, and heat that are generated by cooking. Also called a range baffle filter and chimney, a chimney cooker hood helps to absorb and trap grease so that it doesn't build up on your cabinets and appliances. When it comes to Indian cooking, the use of oil, masalas, and other seasonings, as well as the resulting food stains, all leave their imprint on your kitchen over time. Watery eyes and strong scents from cooking are also significant obstacles for some people. The use of a kitchen exhaust hood may be helpful in this situation. Grease particles and kitchen air are sucked up by an electric chimney. Filters in the range hood and chimney capture grease particles and absorb heat, keeping your kitchen fresh and odour-free.
