Very good. It has tons of features. If anyone farts in your room, its gas sensor detects and send a notification on your phone.

This product comes with a hepa filter tech.Very effective especially for metro cities with peak pollution. Feature wise it is nicely equipped by smart ambient light, child lock, variety of modes and compact design. Features are controlled via app which is the best part. Overall its a good value for money product and easy to install.

I received this product, qorks well and all but whenni check the gas. Its already at Low! New product without gas or used product sold as new?!I would not recommend buying this product.

Philips produces best air purifiers in India at an affordable price packed with lot of features. This purifier looks amazing and occupies very less space. The wifi connectivity is added advantage and setting it up is very easy. Just turn it on and set it at auto mode and forget it, you will be breathing fresh air and difference can be felt. It has helped me getting rid of nose blockages after waking up in morning and noise level of fan while operating is very less to negligible at gentle and sleep modes. Fan speed kicks in automatically if air quality is bad and purification happens in very less time and a notification will be sent to mobile device about the quality of the air.

Very efficient air purifier. Keeps a large room in the blue zone. The app is very useful.

The media could not be loaded. Good product1. Detects the 2.5 accurately2. Cleans out 200 sq m room in 5 minutes approximately3. Detects odour or any other gas present in the room

Product is very good and it is very effective as well. Wish it could have heating mode as well in the purifier because it is very difficult to use it in winters.

Extremely worst product. It deteriorated within a month of use. Furthermore, the service provided by Philips is exceptionally bad. Despite numerous follow-ups with customer support, they dispatched a technician who was unable to repair the purifier and left it disassembled. We continue to face challenges with Philips customer care in our efforts to have another qualified technician sent, as they have repeatedly made false promises regarding the technician's visit.
