Question about Xiaomi Mi Air Purifier Pro

The replacement filters can be ordered from Galaxus, I somehow didn't find any at Digitec.

However, I would first recommend removing the filter from the device and then vacuuming off the dust fluff that sticks to it. I have been using my Air Purifier for years with the same filter. This 3 to 6 months and the filter used indicator does not take into account how dirty the ambient air really is, so if the Air Purifier itself constantly shows a value of 1, then the air is not very dirty.

And one must also consider that the device filter change intervals certainly make sense for really dirty air. For example, in countries where the air pollution is 200 ppm or more and must be properly cleaned, here in Switzerland, vacuuming is enough :). And then reset the unit and continue to use the filter.

If you need a new one, take the grey one, it's the most modern and best. They are all good, but the grey HEPA is the newest.
