After buying the Mijia Smart Air Purifier 6 and the Xiaomi Smart Air Purifier 4 Lite, I went down a bit of a rabbit hole with Xiaomi’s air purifier lineup. Both devices impressed me, but they were covering our living area and bedroom respectively, which left my office without anything. Coincidentally, my office is also the room that is most impacted by outdoor air pollution and I wanted clean air while I work too, so I started looking at what else Xiaomi had to offer. That led me to the 4 Compact, the smallest and most affordable purifier in the…
Hi, and thanks for a great review!
I am wondering whether it is still worth buying the Xiaomi Smart Air Purifier 4 Compact in 2026, given its relative age (released in 2022, I believe). Are you not worried about it being discontinued and filters becoming unavailable? What are your thoughts?
Thanks for your help!
Hi @s.modrak,
Thanks for joining and great question(s)! I see two questions here, so I will answer them individually.
I personally believe this device will be replaced in the near future. The new line of Xiaomi air purifiers (Mijia 6 line) already has its first device, and I believe this will expand this sooner rather than later. I am hoping this improves on a few aspects of the 4 series. However, I have no idea when this will happen, and it’s never ideal to wait for an ‘imminent’ product that never seems to get released. I think if you need a purifier, go for it now. If you can afford to wait, then it could be worth waiting.
I am not too worried about this because there are a range of OEM filters available already. If Xiaomi drops official support, I think it will be possible to get these filters on AliExpress for many years to come.
If this is a concern to you, you can always stock up on 3-4 filters now and hold those in case the filters ever get discontinued.
