I think it's because the cannisters are well sealed and the cap is secured on the breathing tube. So it seems that 3 days is not a definite limit, more like a caveat.So it's been over a week since I opened the bag and I couldn't figure out how to iron it properly to reseal it. So far it doesn't appear the white granules have turned color? I'm not sure what this means. I thought they would turn color and that meant they had to be replaced.
