What is needed are detailed specs on the radio before and after if TX use of the filter is planned. I don't see such information published anywhere. I am not saying that the filters are not good quality. I am sure they are. But in a world full of unintended consequences there is not enough information for the technical ham to make an informed decision. Dozens of eHam reviews and user testimonials that say "works great!" notwithstanding.
