They will work in the imported brands, there is a heavy emphasis on clean fresh air there now,
Daikin, Toshiba, Toshiba Daisekai (my fav), Hitachi, Mitsubishi, and of late even Panasonic, even the high end Samsungs and LGs have it,
For Samsung (silver Nano), these features start only from the 1.5 ton range onwards, the general catalogue is the same giving the impression that the whole range has all the features but a small asterix marked on the 1 ton, so be careful of that. The Wisden range in LG is good, but same price as Daikin, Toshiba etc.
They are all almost the same price , except the Daisekai, which is about 15% more, but its got air purification and filtration capability, no one else has.
be prepared for an installed cost of around 40k for these high end machines. (in Mumbai)
Toshiba is sold by Carrier -
Oh yes, I missed out O general, very good, but again pricey and snooty sales people more interested in "projects". When getting O general, make sure its the imported models, not the ones manufactured in India.
Not familiar with electrolux, like their refrigerators though, the only ones who have 4 shelves (other then Siemens) everyone else has 3.
bottom line, if you want enhanced Air filtration, ~40k installed.
