Xiaomi - Mi Air Purifier 3

MI Air Purifier 3

I bought 2 of them 3 years back from Amazon. It cost me 10k for each.

I had bought for 10k 3 years back.

i love the mi air filters.. i suggest getting two professional ones and you'll be able to clear this out immediately. after that you can adjust them around your house and it will solve your issue. you also need a big humidifier tho you need to think about it access points, but anything that comes from outside into your house. ie, sinks or drains will have service shafts that run up the building etc, and that air is bad. this will repeat in kitchen etc, and there will also be any form of stove/electrical. another example that i don't think applies for you is the radiators/pipes etc

So far its good . I have Mi airpurifier 3, I run it for few hours almost every day . Shows Aqi. I am a dust allergic person. It works for me . So 10/10 till now

Mi (xiaomi) Purifier works great 

>All others are just importing $40 air purifiers from China and then slapping on their own logo (like GFC), Damn, almost went for GFC as I need one urgently. Could you please link me to the purifier they are importing? This would have been my first "Pak origin" device. Already pretty happy with my Xiaomi 3 and 4.

I had MI purifier 3. Good experience but didn't last long. Wanted to check if there's anything new in the market.

I'm have the following purifiers for my family of 5. Phillips 2887 and 1215. Mi Purifiers 2, 3 and 4. Coway Airmega 150 and Qubo 1000C. Not sure about replacing filters every 3 months. We clean it once a fortnight or month depending on the pollution. Mi and Qubo give filter replacement alarms. They say 9000 hours to 15000 hours. So not sure how you came up with 3 months. 90 days x 24 hours is about 2k hours of filter use only. I've placed the Phillips 1215 in the kitchen to reduce pollution in the rest of the house. I didn't think much about Co2 but will see if I can monitor. I counter room cooling with a oil based heater since it doesn't alter the room humidity unlike convection based heaters.

I agree with 3 months, atleast for my Xiaomi. In fact I do 2 months in Oct-mid to Dec-mid for Diwali + stubble burning and 2 months again for winter smog from Dec-mid to Feb-end. Then I go easy with 2 filters for the next 8 months, which I also justify by not running the filters all the time esp during monsoon. I don't like the idea of running the same filter for too long even if it is advertised. The efficiency rapidly decreases based on my testing and I don't want to take the chance of mold/bacteria developing in the trapped dirt, esp in humid (smog) conditions in winter. It's one reason I don't go with models with overly expensive filters advertised for > 6 months. I also agree that cleaning is not that useful. About the AQI spikes due to cooking. we don't fry much, so most of the time, the spike is due to pressure cooker whistle which I don't worry about too much as it is mostly steam and food particles. I haven't looked into longevity of the filter due to this but the high AQI last only a few mins so I've ignored it mostly. I too run 3 air purifiers: 2 in 2 bedrooms and 1 in the living room. I don't keep the bedroom doors to living room closed. I leave one living room window open all the time. The bedroom ones run on medium due to draft issues that you mentioned. I used to stress a lot about keeping AQI perfectly by closing windows and running all purifiers on high but I don't anymore. I can mostly tell now if something it's not working so I just go by feel. I'm also ok with shorter filter life due to window open. Traded for mental peace vs perfection over time. I started with Smart Air in 2014-ish then switched to Xiaomi's around 2018-19. They used to have filters for 1499 so it used to be 18k/year but now it's 2499 (they stopped providing the non-carbon, only HEPA filters). So it's gotten more expensive. Which model do you use. since you say your filter is 1500, I wanna know.

I have Xiaomi 3 & 4 and they work great. They have a store at Fortune it

Check for the availability of filters, not easily available. Hence went ahead with MI, going good for last 2 years

Check during sale period, i got it around 12-13k. Also right now is the peak period when people really buy. I got mine during rains just before winters
