PUREBURG Replacement Filter Compatible with Xiaomi 4 Compact Smart Air Purifier, 2-Pack H13 HEPA 3-Stage Filtration Activated Carbon 2-in-1

First time using used, like new. Great experience. The filters came on time, and in perfect condition. They fit my air purifier fine, and I will be ordering this way in the future.

These are great and fit my air purifier perfectly!

I can't really tell quality of the filer, but Fit with Xiaomi 4 compact

Works? But since there is no RFID, can't tell when is a good time to replace outside manual recording.

The media could not be loaded. Air purifier does not recognise the new filter. I've tried it on two different devices. I've reset both and neither one says there's a new filter. There is now a constant flashing light to say replace filter.
