Xiaomi - Mi Air Purifier 3

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

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

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

Yes. On fan speed 3 i would say it makes just as much noise as a ceiling fan. I have mi air purifier 2, 3 and 4 (models) lol. All of them have noisy-highest efficiency to quiet-lower efficiency modes. Have been using them for 3-4 years now so I guess I'm just used to the noise. It's like when u first turn on the fans in the beginning of the hotter months you notice the sound for a couple of days but later on just forget the noise. You'll get used to it. You can also go into automations in the mi app and decide the logic like 0-100 go fan mode 1, 100-200 go fan mode 2, above 200 go fan mode 3. I have just set mine to fan 3 all the time. I'd rather have cleaner air with more noise. My bedroom aqi is around 20, and living room around 60 (which jumps to around 400-600 when cooking is done or doors are opened for someone to go in/out the house)

New or higher end Xiaomi models (I think 3 Pro and later, 4 normal and later) have a laser particle detector and are dead accurate. Earlier models like the 3H I used to have were less accurate.

Using MI, no hassle at all. Everything is synced with the app and you can change the filter yourself.

Mi Air 3H does a good job with cigarette smoke in a small bedroom. i doubt 4 or 3H would put a noticeable dent in OP's serious need.

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

Mi (xiaomi) Purifier works great 

Yes no brainer. We got 3 mi ones at home

Even my MI is struggling to keep aqi below 160 today. Need to re seal doors and windows since ive shifted recently.

Buy the Mi don't look for anything else
