The introduction the KXFL3 manual described these filters. (https://ftp.elecraft.com/KX3/Manuals%20Downloads/E740165%20Elecraft%20KXFL3%20Option%20Rev%20A3.pdf)
They are not IF filters in the sense you may be used to. In the KX3, selective filtering is done in the DSP. These are roofing filters, at baseband, that sit in front of the DSP, and serve to improve the dynamic range of the radio. They switch in automatically, and there’s no way to select them specifically (and no reason to). But the display does show you what roofing filter is active.
