Review: A vital device to see what our eyes cant see - why did i buy this: i do a lot of WFH and realized i get too tired and exhausted after just a hour. Dk why i bought this and found out that CO2 accumulation was way outta normal levels in my room due to poor ventilation. now i remedied the CO2 issue and also found out that my DIY air purifier works really well. normal AQI is around 70-80 normally in my region. Features and good experience with this product : built in battery lasts for a day but this device is designed to be connected to power at all times. CO2 measurement can be calibrated and is set to off by default built like a brick which i honestly did not expect measurements respond pretty fast to changes which i really appreciate. has a smoke alarm kinda feature where if AQI crosses 100 it beeps. looks nice in my room. The cons and bad experience. backlight is not bright enough experienced a glitch where CO2 ppm was stuck at 500 had to reset the device i wish it lasted atleast for months before charging if there is bad ventilation temperature reading is unreliable Something i want to say: i read a lot of reviews before buying this product and it seems like the seller is listening to feedback and fixing a lot of issues users experienced my experience till date is almost flawless except the problems mentioned above. which is also something i didnt expect. i expect this thing to last atleast 3 years or so and if it fails i will update my review as this one is not cheap at all atleast for me. overall i can confidently recommend this product if you can accept the shortcomings mentioned above
Review: Broke after 1 day - It was working fine for one day (showing value of 40 indoors), afterwards it shows a reading below 5 all the time even in highly polluted areas. The AQI reading is still incorrect after fully charging.

### ⭐ Broke after 1 day
*by A***R on 1 February 2026*

It was working fine for one day (showing value of 40 indoors), afterwards it shows a reading below 5 all the time even in highly polluted areas. The AQI reading is still incorrect after fully charging.

### ⭐⭐⭐⭐ Does the job
*by S***. on 14 January 2025*

It does the job well. i think it may be detecting water particles as pm but that's not a big issue cause it also has humidity sensor so you know how to interpret the readings. Worth it.
