I don't know where you live, but I take the filters to the recycling yard in Spreitenbach. A friend of mine just throws them in the rubbish.

The best thing to do is to take it to the nearest waste disposal centre, where the staff will be able to give you information.

Hello, When I look at all the air purifiers, they are all built the same and have only slightly different functions. So I think this one will also fit in the 3C. Greetings

Anti-formaldehyde = The Xiaomi air purifier filter can effectively absorb PM2.5 particles, dust mites. Covered with the special antibacterial layer, it can kill the bacteria. The activated carbon can eliminate the pollutants and odours in the air. Is a filter that filters more than the S1. S1= Captures up to 99% of dust, pollen, dander, mould spores etc. less. So it is a standard filter without chichi.

I have just looked at the filter in detail. Unfortunately, this is not apparent in any way. Based on my experience with it, I would now guess TK-A (For general air filtration, odours, kitchen exhaust air, solvent vapours, welding fumes, diesel odours), hardly TK-B. Much more likely, however, no classification at all. An odour reduction for cooking odours, smoke flavour (oven) is clearly "smellable" over approx. 1/2h according to my perception.

This filter should work with the Xiaomi Mi Air.
