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.

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!

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

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.

It's hard to breath around considering the air quality in East Delhi. Thanks to my childhood friend - Rishi who suggested me to buy this Air purifier which has changed my life manifold times. As my parents are aging, I always wanted to gift them something of need that adds value to their health and life. When we added this purifier for the first time - it gave AQI of 300 which later purified up to 50. Now, when we switch it on - it starts with 100 -150. Thats the change that made us surprised which we never imagined . Good product, totally recommended

Very premium looking air purifier. Perfect for people who do not want to compromise on the aesthetics. It has two hepa filters which makes it very effective and efficient

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.
