Hi Peter You can't go wrong with a great mask like that, but Gump in Germany feels that since the OA vapor recrystallizes in the air, that you only need a good particle mask--not organic vapor. I'm just reporting, not recommending. I've never used vapor myself. Randy Oliver -- Visit www.honeybeeworld.com/bee-l for rules, FAQ and other info ---
