Xiaomi Mi Air Purifier HEPA Filter Suitable for Xiaomi Air Purifier 2/ 2S/ 2H/ PRO

God knows if they really work. But I have noticed the air after cooking or smoking/farting etc when purifying cleans the air smells/oders despairing. But I am not sure on the pm2 particles and others stuff they say it sucks up and gives back cleaner air . I do see small amount of dust build ups and hoover it away with my lovely Henry hoover sucks it all up. I do suffer with winter and summer allergies but no differences that I have noticed. In the dark flash a torch and you will see dusty all around. But everything is a mind game. And only manufacturers know well if their products work or not. Amazon sellers are just selling products not their faults.

Took some measurements and a gamble on this as I could not get hold of any filters for my Acekool AF2 air purifier. Fits perfectly and works like the original.

I am a teacher and in a group at risk of Covid complications. I purchased one of these at Christmas just as Omicron was taking hold in schools. This was one of only a handful of HEPA filters suitable for use in large rooms, making it ideal for my classroom. On full power it is quite loud so I don't use that all the time. I have it running on II (quiet and unobtrusive) when I am wearing my FFP2 mask, then crank it up to III for 10 mins before I take my mask off. I also keep two windows open at all times. So far with this regime, I've managed to dodge Covid like this. I have also stopped suffering from Hayfever do I know it's working. I would highly recommend this HEPA filter to anyone needing to clean air in a large space such as an office.

Dont think this is working. Its very noisy

I have this new Grey Xiaomi HEPA filter, and the purple one. Why does the purple one feel like it is making the air cleaner?When I enter a room that has the purple filter I feel like i'm walking into a spring meadow, like my health is genuinely improved. But with the New grey HEPA filter I feel like I have just vacuumed the house, no clean smell, no anti bacterial layer, and the air feel dry. The Purple one just felt 'right', this one is weird, is it lacking the clean scent layer and perhaps cleaning the air too much? It's like tasting wine, when you know, you know.This filter has been released during the coronavirus pandemic - has Xiaomi increased production of filters to meet demand and somehow quickly come out with this strange hepa filter and branded it as better 'hepa'? Lots of questions I have, but if you want my recommendation, go with the purple filter.

Is a filter and is doing what is suppose to do.

FAKE! Will not work or initialize in fan and system say the filter is bad
