We had the same happen to ours, indeed the bagged spare crumbled to dust faster than the one that was fitted!
I simply re-wrapped one of the metal formers with a cut and glued piece of foam that I salvaged from a skip - it looked like it'd been packaging off something delivered by post - which looked/felt to be about the same thickness and density as the OM Filter foam. I'm sure there'll be someone along shortly with some proper knowledge/qualifications to say why you shouldn't ever do something like this, but that was fitted perhaps three years/600 hours ago and I've never had any problems or noticed it making any difference.
