A ductless chimney is a type of kitchen chimney that does not require an external ducting system to expel the smoke and fumes generated while cooking. Instead, it uses a filter that traps the smoke, fumes, and grease and releases the purified air back into the kitchen. This makes it an ideal solution for those living in apartments or houses where ducting systems are not feasible or cannot be installed. Ductless chimneys are suitable for Indian-style cooking, which involves a lot of frying and cooking with oils and spices. However, they may not be as effective for cooking methods that produce a lot of steam, such as boiling and steaming. Ductless chimneys are noisier than ones with a duct, and they usually require more maintenance. They are also less effective than ducted chimneys in terms of suction power. Despite these drawbacks, ductless chimneys are a vital component of any Indian kitchen, as they help to soak up the heat that is generated while cooking, absorb strong aroma, keep air circulation constant, remove unpleasant smells, and keep the kitchen tiles clean.
