Some of the polypropylene glycol antifoams are sufficiently water soluble
that they ought not plug a sterile filter if the medium plus antifoam is
filtered. You can't easily filter sterilize the antifoam by itself because
the viscoisty is rather high. You also could steam sterilize the antifoam
and then add it to the medium after the latter has been filter sterilized.
