Filter life Braun IQ

Garry
Hi, any users of Braun IQ experienced reduced life of ultrafilters? We only use at one unit and every machine has failed with df/hdf filter blocked message with inlet press to filters at >700mmhg with each machine showing around 40-50 treatments left and around 400 hours.  Water quality good at 0cfu/ml.  As we're new to the IQ unsure if this is an issue others have come across with the equipment now monitoring ultrafilter pressure.  Possible a bad batch of diacaps but can't be sure until Braun investigate or next replacement window comes around.  As it mainly occurred mid treatment I'd rather get is resolved before then. Cheers
