AC1711/61

Went with Philips AC1711. Trust Philips blindly given past experiences and filters easily available and long lasting.

I am using this from Philips: https://flipkart.com/s/EQhmMjNNNN Works well, has an AQI display. During Diwali it brought it down from 650+ to 50 in around 30-45 min in normal mode. Doesn't have connected features though. HEPA Filter access is easy. Has 4 modes including sleep which is super silent. Got it for 9k during sale. Edit: correct link AC1711/63 CADR 300 m3/h, covers upto 380 sqft Portable Room Air Purifier on Flipkart https://www.flipkart.com/philips-ac1711-63-cadr-300-m3-h-covers-upto-380-sqft-portable-room-air-purifier/p/itme5e1401e0c02f

I opted for Philips AC1711. I think it's out of stock now. But I found Coway and Sharp to be good as well in my research. Eureka Forbes is also good. It's cheap and feature-packed with high filtration power. The only cons is that the air filter refill is costly.

I have Philips AC1711/63, it is amazing, no complaints yet. It is a bit on the pricey side but so worth it
