Pictures attached for 3 bathrooms, first 2 are from same bath

Its always best to go for a ducted chimney as foul air is removed out of the kitchen. A ductless chimney has charcoal filters which need to be replaced periodically and it just recirculates the air. But if u have no choice to go for a ducted option, then u can go for ductless model. We have used Elica models, not in mumbai though . Didnt have any problem as such. Also check the service availability in your locality. Faber is also a good option. Also a baffle filter is much easier to clean than a mesh filter in case of ducted chimneys.

Nomitha, of the two Kaff is better rated. Faber and Hafelle are better in terms of service as far as Bangalore is concerned. PS: Solely based on our experience. Thanks, Nitin Cornerstone Designs, Bangalore.
