Which of these filters also fit another device
Fit rarely carries across generations, so this lists only the exact models each product is separately documented to fit.
What looks like it fits GoPro HERO13 Black but does not
Lens mods and ND filters sold for HERO9 through HERO12 are the common wrong buy: HB-Series is a different mount.
These sit in the same filters aisle and are confirmed for a different exact model. We have no published answer saying any of them fits GoPro HERO13 Black, so treat them as unverified for this device rather than as a fit.

Coming from an older model
Why a previous-generation filter may fail here
HERO13 Black introduced the HB-Series lens system and a magnetic latch mount in place of the older folding-finger mount.
Enduro batteries and the general mount ecosystem carry across from HERO12, but lens mods and filters made for earlier HERO generations do not attach.
