Only mode of survival in this AQI of NCR. Helping us a lot. Clean air by this air purifier actually feels different and perfect. A sense of freedon

I got it today only, will update my review later. But as of now it exceed my expectations. I can feel change in my rooms air. It hardly takes 5-7 minutes, to change the room’s air quality. Its very effective. But again I am saying its too early to judge . Display indicator also seems working accurately.

Tested for Delhi NCR (AQI > 500). A purifier must be able to keep the room AQI below 20. This purifier works best at max speed only (PM2.5/AQI goes as low as 1 or 2) Gives minimum around 300 PM2.5 in night/sleep mode (so doesn't help much here) Automatic mode goes from high speed to low speed as soon as PM2.5 hits 59 and so it isn't able to lower it below 30 due to low speed (goes till 35 or 40 only). Its just the high speed which reduces the AQI most. Takes very low electricity (as much as an electric bulb) so using it on high speed is not costly at all, 21W only. In cold weathers, the high speed makes the room even cooler due to the fan so besides that it works very good. Go for it.

Used it for a day and its really doing a good job. The difference is obvious. Even if we take some extra numbers being shown into consideration still its a great thing to have in this pollution. The before and after aqi is day and night! The auto mode works perfectly.

On a utube video, the person showed that the aqi display is kind of gimmicky...but the thing is if u run this for 1 hour (full speed), u r gonna get what u need. Just don't trust the aqi display blindly..! Rest is fine
