I bought a Mi Air Purifier two Diwalis ago when I became really concerned about indoor air quality with a five-year-old in the house. My rented house has old iron windows and it can’t keep out anything, certainly not dust or even smaller pollutants. But I was not sure I should buy an air purifier, most of which cost over Rs 25,000 at that time. That’s when I went for the Mi Air Purifier which was the most affordable option. I have not regretted it one bit and the air purifier has been whirring away, almost non-stop, for two smog seasons. So when Xiaomi announced a new version, I was keen to test it out.
Xiaomi Mi Air Purifier 2S review
The Xiaomi Mi Air Purifier 2S is almost similar in looks to the earlier version that I have. There are some improvements though. There is an OLED screen on the front that shows the temperature and humidity, PM 2.5 levels in the room and the mode the purifier is set on. Also, there is a sensor on the top now that seems to be on the lookout for particles in the air so as to adjust the filtration levels. Plus, the power cable now is detachable, not that it should bother you in any way.
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 in about 10 minutes. Much later in the night the levels had fallen to about 45. But that did take some effort from the Air Purifier.
