OEM air filter - manufacturer?

[Beez540]

I've seen several different sites selling OEM air filters for BMWs and I've seen 6 or 7 different manufacturers of them.

So which one is right, best, or are they the same?

I've seen Mann, Mahle, Bosch, Hengst, etc.

Any help would be appreciated.

Mann, Mahle, Bosch, are all good and also OEM spec suppliers. Not sure about Hengst.
