This is a BMW video about counterfeit filters, not legitimate aftermarket filters, but it does show what can happen. If you watch to the end there is a durability test where the filter dissolves.
BMW in the Middle East has issued a press release about increased number of counterfeit parts coming out of that region.

If I had a filter dissolve on me, and I thought it had been changed not too long back, I would check the markings on it and suspect it was not OE quality. If it had all the OE markings, I would suspect it was counterfeit.
