Ah, but I got an email that confirmed the essential facts we both already

1.  The filters DO remove chloramine; the conc of ammonia/um that gets
through is not detectable with an aquarium test kit.

2.  I've been using it for years and on community aquariums and even after
3,000 gallons have passed through I still don't lose fish.  When you first
expressed concern,  I gave it some thought & for a while pondered whether I
may have lost bushynose plecos to undetectable ammonia/um; till others
confirmed they lose bushynose after water changes fro R.O. units too.

Thus, the facts are the filters eliminate the chlorine and reduce the
ammonia/um to levels your common test kits can't detect.   Thus, since
undetectably low ammonia/um levels are always present in any tank, why
should I assume that the undetectably low ammounts of ammmonia/um that
might escape the CBR2-10R filter would  harm my fish?  Especially when I
have seen no evidence of this.
