Xiaomi - Mi Air Purifier 3H

We have 2 Xiaomi 3H running at home for now ~5 years. Got good testresults by Kassensturz Concerning their filter quality and I'm overall really happy aswell.

Xiaomi 3H. Namomonitor sa app. Thougj personally, pinatatagal ko famitin kahit 0% na. Usually 3 to 6 months. Kainis lamg itong unit ko kasi mahirap linisin yung top ng hindi babaklasin lahat ng side panels. kung hindi gagamitin, make sure na coveran yung ibabaw para hindi mag alikabok.

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.

As a single point of comparison, the PM2.5 reading shown on my Xiaomi 3H reads about 10% lower than my stand-alone meter when sat atop the Xiaomi. Also note that they both read PM2.5 ug/m^3 The AQI number is a calculated value with ug/m^3 as a component, so will be higher than the actual ug/m^3 shown on a meter. One downside of an air purifier with a built-in meter is that it may have a small fan to push air past the sensor, these small fans tend to develop noisy bearing. The small sensor fan on my Xiaomi appears to have this issue after about 3 years of almost constant use. I also have a Bwell air purifier that was about triple the cost of the Xiaomi that hasn't developed this problem yet, but it only has about half the hours on it that the Xiaomi does. Don't have a model number for the stand-alone meter, but it was around 1750 baht when purchased 3 years ago.

By a funny coincidence, I was just checking the output of my Xiaomi 3H with a fresh filter. The room showed a PM2.5 of around 22 ug/cm^3 and the output of the Xiaomi showed 9 to 10 ug/cm^3 when checked with a meter. The display on the Xiaomi showed 10+/- 1. This is with the Xiaomi on auto, running at a quiet setting.

Any HEPA filter air purifier will work. Has to be HEPA filter. Carbon filter won't work that well (takes an hour at least). I used to be a heavy smoker. I smoke literally beside the air purifier that's only meant for my smoking activities. Clears the smell in the room within 15 minutes if it's a new filter. Does not remove the smell from your clothes though, just the air. Only caveat is you need to smoke beside the purifier for it to work decently. Like ash tray and cigarette as close to it as possible and blow smoke into the purifier. I used Xiaomi 3H and swear by it.

I got the Xiaomi 3H as filters are cheap, design is clean and you can flash it with ESPHome.

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

I have Xiaomi Air Purifiers in each room. Big one for living room, smaller ones for smaller rooms. My particle sensitive partner (allergies & athma) feels the difference Edit: as for why I trust it, did my share of research at the time, like airflow and all. Beside that, the Pm5 score readings have been very reliable, reflect every messy event in the house, the level of pollution when we open the windows, and goes down steadily when we close all doors&windows. New filters can be ordered on Lazada btw
