Hi, sorry my question was not good. Is it a standard scrubber cannister that you fill yourself? and, what is Extedair?
The ExtendAir cartridge is from Micropore, and used in the DiveRite Optima CCR as well as Inspos, Megs, Dolphins, Azimuths, LAR Vs etc with various adapters or replacement scrubber cannisters.
Pre-packed cannisters are usually inserts for the cannister that contain granular absorbant packed by manufacturer. Some military rigs had that over the years, as well as the Frog and I believe the Fieno, too. Real success stories, those two units.
Idea behing both is to open the scrubber cannister, place or replace the cartridge/pre-packed container and not worry about properly packing the scrubber with granular sorb.
Problem is both tend to be hard to come by in most places and tend to cost quite a bit more than granular absorbant.
