Navien Peakflow E replacement filter question

[Silverexpress01]

Hello, I've got an older Navian NPE-240A tankless water heater, and it is using the Peakflow E filtration system. They no longer make the filter (GXXX001726) for this, and so I was wondering if the newer Peakflow S (GWFC110GD001) is a drop in replacement or if I will need to replace the whole entire housing assembly for the new filter?

Regards,

Jose

I also have Peakflow E. Installers replaced GXXX001726 cartridge after 2 years with GWFC110GD001. I now have small beads plugging the screens on inlets to washer, Navien NPE, and other in-line screens. I suspect the cartridge is failing??

Just added... confirmed my gwfc110gd001 failed and leaked the microbeads throughout my water system. argggghhh. See photo.
