Who the Symphony Diet 12T 12-Litre Personal Tower Air Cooler is for

Buy it if: Anyone in dry inland heat wanting cooling at roughly a tenth of an air conditioner's running cost.

Avoid it if: Anyone in Mumbai, Chennai, Kolkata or any coastal humidity -- evaporative cooling does not work in damp air.

Who the Faber 60cm 1200 m3/hr Auto-Clean Chimney is for

Buy it if: Anyone with a kitchen around 20 cubic metres who can duct to an external wall.

Avoid it if: Anyone who cannot duct outside -- recirculating a chimney through a carbon filter removes very little Indian cooking smoke.
