This is a must buy for every home irrespective of any location in India. I have been having dust allergies, sinus headaches and eye irritation since my childhood days and now after installing Mi Air purifier 4 I dont have any of these problems anymore. Digital indicator is really helpful and negative ionizer and laser sensors works like charm. Its very quiet. Worth buying it. Your kids will thank you for having this. Blindly go for it.

Great product with a capability to reduce dust by approximately 3/4 e.g. if atmosphere pm2.5 is 300ppm , it will be reduced to upto 75ppm inside room , only if minimum ventilation is provided to take care the CO2 we generate.
In my case , I have found in my area that the ambient has CO2 at ~410 ppm. If we open one window door to only by 5mm clearnce, the CO2 is being maintained from 500 to 600 ppm with 2 adults inside the room , based on wind velocity and direction. This adjustment 5mm clearance was achieved measuring with “calibrated stand alone CO2 cum PM 1.0, 2.5 , 10 measurement meter”
One more example with above ventilation arrangement, the machine is in auto and ambient air pm2.5 at 198ppm, room also at 198 ppm, the fan speed reached medium (sound audible), it took some time to reach 85ppm and then it took 1min from 85 ppm to 68 ppm, now fan speed changed to low speed in Auto (sound is inaudible), this ppm starts increasing gradually to 85ppm in 1.5 minutes, now fan speed increases to medium again and the cycle repeats as long as outside pm 2.5 is 198ppm.
Similarly the fan speed (so it’s sound) can be very high if ambient pollution is very high.
It needs external cleaning of it’s HEPA filter every month based on pollution. The sensor may need cleaning every 3 months for accurate readings (if sensor mal functions , it is to be cleaned first and check before taking to any service center).
It has a simple filter element with spare availability and capable to give atleast 3 times the specified life, if we clean the HEPA filter element externally with vacuum cleaner regularly.
It does not have ozone producing UV rays or ion generators, which if not properly designed ( specified to customes not worry) may pollute the air with ozone.
It has particulate count PM 2.5 meter which is very accurate, in addition it change display colour according to pollution zones to know the condition of air in the room (The readings were authenticated with above calibrated stand alone meter CO2, PM1.0, PM2.5 and PM10).
We have to keep it on Auto to facilitate to change flow /speed based on pollution level (it’stemperature and humidity meters are also useful).
Update 24.04.22 (still under warranty) : It developed some abnormal sound just audible , when we go near to it (like kitch, kitch, kitch..) at lowest speed. Doubt was on loosening of bottom locknut of fan and sound is ruled out from fan bearings, this diagnosis also strengthened by the observation that the above sound disappeared, when it is made upside down.
Bottom cover opened , side covers opened , the bottom grill was moved down by lifting lock with columns and it was found that the button lock nut was in slightly loose condition as anticipated. The abnormal sound and mild vibration problems are resolved after tightening the nut (with 13mm tubular spanner already available with me), holding the fan (nut is a self locking type) and assembled back , But opening of side covers is a tricky and risky job (some locks may be broken, use hand gloves to protect hands from sharp edges , they may open in jerky motion ). I have made some top grill locks bottom side open by cutting (modification) so that I can open the panels easily in future. However another Mi Air purifier 2S is working almost continuously without any problem from last 3 years.
Update: 02.07.22 High abnormal sound observed. This time I want send it to service center , but while lifting some material flied off from grill. So, when I run it upside down many foreign material came out like some bodies of flying ants , their wings and one baby lizard. Now again it is working normal.
17.01.2023 The filter replaced as the flow became very low after 14 months of almost continuous use in high PM 2.5 conditions. Hence the time taken to reduce pm 2.5 had increased to an extend that it is unable reduce less than 150 , while ambient is at 300. The effectiveness restored after filter replacement.
