ExtendAir cartridges have many advantages, not the least of which is its ease of use. This will be most obvious to those who have been using granular adsorbents, as loading a rebreather canister has historically been the subject of much training and discussion of technique. The performance variability resulting from individual differences in loading methods is virtually eliminated with ExtendAir cartridge technology.
					With a rebreather designed to use an ExtendAir cartridge, loading the canister is as simple as opening the package, taking out the cartridge and sliding it into the canister. An ExtendAir cartridge can be loaded correctly in about 30 seconds, compared with 5 to 15 or more minutes using granules.
	There is training required to learn how to use ExtendAir cartridges and how they work, but the bottom line is a much simpler and user-friendly technology.
