Its a genuinely great air purifier. My breating improved vastly and it covers a large area to purify the air. Its smart features are great to use, mainly its connection to the phone via Air+ app. You can switch it on and control it through your phone. The price is also great as compared to dyson etc. Its quite silent amd we can have a peaceful sleep. Looks very modern too.

it is very good air purifier for my home, works well for my living room and bed room size. AQI display is very helpful to check air quality anytime. app is also good. very easy to use and setup, no issues so far. overall happy with the purchase, worth buying

I recently moved to Gurgaon with my husband, so we have purchased this air purifier for our hall area in our 3BHK flat works fine, and the noise level is pretty less The size is also not very big. It is connected to our Wi-Fi. We can also operate it from the mobile app and set the schedule. I must buy if you feel like dust is a problem in your area.

The air purifier is amazing — it easily detects current PM levels and automatically adjusts the cleaning mode. The app connectivity makes it even smarter and more efficient for maintaining clean air. Solid build quality too. Definitely worth trying!

Extremely high running cost. Do not buy. The pair of filters are advertised to have a 12 Months life but they last less than 6 months. It costs INR 6000 for a pair so that would mean that every year you would have to spend INR 12000 just on the filters. The machine is silent and works well but honestly at this kind of running cost, pls look for something else. In just 2 years, this would cost more than a dyson.

The purifier is really working well in my living area - I noticed a clear difference in the air quality within a few hours when its working. There is hardly any sound even at night. The best part is that it can be controlled using a smartphone, which has made it very easy to use.

Auto mode and other slow modes just filter air in and around the purifier. If you want results - even in a small room, put it in turbo mode for 30 mins and then maybe bring it down to auto mode. Air purifier does work. My kids allergic reaction to dust and morning colds have reduced significantly. There is quite a bit of sound on turbo mode. The key metrics when choosing air purifier is how much volume of air it's able to recirculate in a time frame.

I lot quieter than other ones, easy touch top, i liked the light indicator for pollution level . Not too heavy. Reduced AQI for (6*8) room in 12min by 88%. App control works okay. It’s comparable to Dyson one in less cost. No fan exposure so safe for babies
