Qubo Q500
The Qubo Q500 lists True HEPA H13 filtration, a PM2.5 sensor, 500 sq ft coverage and app and voice control for about ₹11,990. It is the cheapest app-connected purifier we compared, with a single PM2.5 sensor, a 1-year warranty and fan noise up to 55 dB.
Read the review - Cuckoo
Cuckoo A Model
The Cuckoo A Model is a Korean-made purifier with a listed 300 m³/h CADR, a three-stage filter and an LED panel for about ₹15,999. It has no app or smart control, so at this price it costs more than app-connected purifiers that list similar airflow.
Read the review - Coway
Coway AirMega 150
The Coway AirMega 150 is a popular, simple purifier with 303 m³/h CADR and H13 HEPA, but it is an older design: in our testing it has no sensor-driven auto mode and no app, so it is essentially a fan with a filter. At about ₹15,000 newer purifiers give more.
