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!

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.

Pathetic product, we have received a malfunctioning product and the technician is saying buy a new filter as the product is giving a foul smell We have a warranty of 2 years and The techician is is saying to us it without a filter Pathetic service They are saying us to to buy a new filter Or put the filter in open air Have received a bad smell product with defected filter It’s a refurbished product that we have received Need a solution immediately

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.

This air purifer comes with high room coverage it cleans my 250sqft room in 10 minutes. Aqi level changed from 200 to under 20 with very less noise
