There is no prefilter so I added a 3M AC filter.. this will make the filter last longer.. MI doesn't want you to do this... Else how will they sell the filters!!
The Xiaomi Mi Air Purifier 2S is silent, even when it is working over time to clean the room. The real test for the air purifier came on Dussehra day. Around dusk the PM2.5 levels were around 40, which is good, but certainly not great. But after scores of Ravanas had been send to their smoky ends across Delhi, the numbers shot up to around 172 indoors. Outside, the numbers were over 260, scary when Diwali is still a fortnight away. In ten minutes of running in Auto, the Xiaomi Mi Air Purifier 2S was able to bring the numbers down to a more breathable 82. Much later in the night the levels had fallen to about 45. But that did take some effort from the Air Purifier.
changes reading drastically one moment it shows reading as 225 and next moment as 31 again 176
Value for money product, very easy to operate
I’ve been an MI fan as I’ve been using MI mobiles for a long time now. But my view about this air purifier is not positive. It works really slow at night mode and most of the time shows very unrealistic AQI even if the room is closed. I bought it this month itself for my kid’s room but looking at quality and performance of this device, I would look for some other better alternative as this hasn’t been a good buy. Sorry MI but its a shame for you this time.
Pros -- -- The product works as expected, reduces PM2.5 efficiently. -- Using it in Delhi on top floor, closed room. Noise level is so low, that you may forget its still on. -- When I turn it on PM2.5 is around 190 AQI (very bad for lungs), then within 5 minutes (in manual mode) it brings it down to 40 AQI which is good enough. -- After using it, when I go out I can finally feel how pollution smells like. (It's also a trade off, because, if your body is sensitive, you may catch cold. Take necessary precautions when you go out, if you have sinusitis or asthma, it will feel like being a non smoker suddenly exposed to smoke). -- AQI sensor works well, except occational glitches (as per reviews, it is expected to be better than old model). Humidity sensor works well too, not sure about the temperature sensor (so far its been 26deg, most of the time). -- It has a led display (with PM2.5, temperature, humidity, wifi status, current mode). The display was not present in old model (big plus), which is also listed on flipkart at the same price (misguiding). -- Received one firmware update through app so far. No big improvements though. Cons -- -- For delhi, auto and night modes are not good enough. When I leave it for four hours or more, PM2.5 goes above 90 (75 being the safe level). -- But manual mode can quickly use up the filter. (Also, when I bought this product, filter was sold out in flipkart). The filter costs around 3000rs, needs to be changed every 4-6 months depending on the usage. -- To change modes from auto, app integeration is required. Product only has a power button. -- Android version of the app is very invasive in terms of privacy. So much for a Chinese product. Check it on playstore (MI Home). I'm using it on iOS now. -- In the app, there is no option to automate using PM2.5 levels, only time based automation is available. (This could have been a big plus for delhi users).
good air purifier worth the price
you will feel an instant difference in air quality it's almost noiseless , wouldn't even know it's on. live display of air quality is great, which is not present in other products biggest problem is connecting it to the network, it doesn't work with certain routers, but it easily connects if you connect it to hotspot network from ur phone. Mi needs to resolve that issue
Good performance. successful device. Fresh Air
Great practical design.Good connectivity with app.The air you breathe suddenly feels much lighter and better. Helpfull on those bad days when the AQI is bad.Use SAFAR app to know air quality outdoor in your locality.This will give u great idea whether u require air purifier on that day or no. Irrespectivw keep it on during night for that much better sleep in night mode.Has auto timer function in Mi Home app.Great overall.
