On the Micropore cartridges there is an interesting technicality. We cannot use granules, by law. It must use cartridges. I will explain:
The law in Europe says rebreathers must meet EN14143:2003, and that requires meeting EN61508. The latter applies to any system incorporating any electronics or electrical system, or programmed system.
This means if the CCR has a controller, EN61508 applies to the whole lot.
CCRs using granules cannot meet EN61508. This means any CCR marked CE without a Micropore cartridge, is a lie.
The reason is users have too much variation in packing. A recent posting to select Inspiration users from Martin Parker highlights this problem. Not even all the instructors APD trained know how to pack it safely.

How about prepacked granules then?
Something like this maybe:
Intersurgical Complete Respiratory Systems. News
Or the RGUFM, didn't the Japanese Fieno have that? I have also seen drawings of Russian scrubbers for UW use with prefabricated scrubbers.
Not that I know of any rebreather that is for sale today that uses prepacked scrubbers.
