I don't understand your comment.  A filter is a filter.  Assuming we're talking a band reject filter, if the filter is between the source of the AM signal and the rig, even if the source is due to rectification, the filter should still do its job.  Why would it not?

Probably Array Solutions, DX Engineering and maybe VA6AM have broadcast filters however if there is rectification occurring they will likely not help. At my station in Chicagoland I could hear a mix of two AM broadcast stations on my 80m TX antenna which was quite annoying at times. I never tried a specialized filter because I did not feel that it was a RX overload issue.

I remember someone recommending a brick wall AM broadcast band filter some
months back.  Was a little on the expensive side but.if it works. Anyone
recall that thread and the name and/or contact for the manufacturer or
dealer?  Thanks.   - Mike
