Mi Air Purifier 3H

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.

Depends. Earlier/cheaper models do give a lower AQI. Higher end models with laser sensors don't. My Xiaomi Pro purifier is much more accurate than my 3H was.

Xiaomi Mi Air Purifier 3H can be flashed it with ESPHome for local control. Some disassembly required, but it wasn't that bad. https://github.com/jaromeyer/mipurifier-esphome
