PVDF filters are compatible with BB and BA, never had any issues while using these filters. I've even used PES, those filters can usually handle a small amount of BB (if you filter it fast) without starting to break down.

My advice about those membranes is you can either sterilize them for real, I can send a small summary/Article that I've written about sterilizing equipment if you PM me. Or you just use it as is, that's what I've done.
If you decide to use the membrane discs as is, brew small batches that you'll use up in a short time.

thank you THX; as always, you’re the man!
