Xiaomi - Mi Air Purifier 3H

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 

>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.

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.

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

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.

Xiaomi is THE best, as they are properly engineered devices with extremely good airflow (airflow is much more important than filter technology). However, Xiaomi has gotten a bit expensive over the years. My recommendation is that you shouldn't get any cheap home-made purifiers that you may come across on social media. The only local manufacturer that I'd recommend is Royal Fans. All others are just importing $40 air purifiers from China and then slapping on their own logo (like GFC), only to sell them at $200 in Pakistan. Apart from Xiaomi and Royal Fans, if you have the time and motivation, you can go for a DIY purifier, but PLEASE do not blindly copy some cheap online design. I would highly suggest that you visit r/crboxes to learn about the new CRbox movement, that is strongly against over-paying big companies for low CADR air purifiers. In order to do a quick PhD in air purifier science, please watch the following video: [Most HEPA Air Purifiers Are A SCAM (There's A Better Option)](https://www.youtube.com/watch?v=gaQTYrisieA) I currently have a good Xiaomi Air purifier that I bought in 2021. It has been running non-stop since that day without a hiccup. Extremely satisfied. Today, I even bought a Royal Fan for 30k. But I did so because I needed the device urgently. I would highly recommend all others reading this comment to go for a DIY air purifier. If you investigate r/crboxes in detail, you can easily make a DIY air purifier that is much better than Xiaomi or Royal Fans.

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.
