Buying Guide Kitchen Chimneys

What are Kitchen Chimney?

Kitchen chimneys are appliances that absorb smoke & fumes from the kitchen and keep the kitchen grease & smoke free.

Factors to consider when buying a chimney

1. Mounting

  • Wall Mounted: Chimneys is fitted against the wall. These are designed for traditional kitchens where stove is located near the wall. There is minimal ducting/pipes required.


  • Ceiling Mounted / Island Chimneys: Chimney is fitted in the centre of the kitchen. These are designed for modern island shaped kitchens where stove is located in the centere. There is substantial ducting/pipes required.


2.Popular Technologies

  • Auto Clean Chimneys : When the cimney is working, the coil that cover the motor gets heated up for 15 to 20 mins. The oil gets liquidized and is let out. The chimney stops after auto cleaning itself.


  • Ductless Chimneys : Unlike a ducted chimney, which vents air to the outside, a ductless chimney consists of a fan (or a blower, motor) with a charcoal filter that sucks up grease particles heat, smells, and smoke, filters it, and then recirculates it back into the kitchen. This is specially useful when there is no exit vent from the kitchen.

The type & filter surface area determines the quality of filtration. Typically, higher number of filters indicate higher surface area.

The suction power gets hardly affected even if the oil gets collected in the first layer. Perfect for indian style of cooking.
    • Maintenance : Needs celaning once in 5-6 months. Gets rusted with use. Some modles have easy removal while others require a technician. The filters need change in 4-5 years.
