If you would have got an AC with Air purifier, you wouldn't need a separate air purifier. How much did that Daikin AC cost? Check if it has inbuilt purifier?
One such AC with built in air purifier is Panasonic AC model: CS/CU-NU18ZKY5W
Anyway for good air purifier, checkout: Coway AirMega 200 (AP-1018F).

I dont want to mix things...A/C & Purifier...Purifier means need to change filter some time...Otherwise, its marketing tactics
I inspect
Panasonic AC model: CS/CU-NU18ZKY5W checked in this model at the local showroom. After removing front cover checked there is a small 2 filter strips was pasted exiting filter...Its a pure scandal for market gimmick...Marketing salesmen also do not recommend this model.
Daikin FTKM50UV16VA @ 47,990
I think this is suitable for me...Coway AirMega Aim Professional Air Purifier
