This is an odor threshold issue.  MeOH has very poor odor detection
hence you can't detect cartridge breakthrough.

Subject: [DCHAS-L] MeOH and organic vapor cartridges

I recently learned that organic vapor respirator cartridges do not
adequately filter out methanol. Can someone explain why? Are there other
common solvents that these cartridges are inadequate for?

Thanks,
