I'm planning on getting the oxygen masks that come with nebulizers. They have 2 holes on each side and a medicine chamber directly attached to the mask.
Is this mask ok?
Should I close those holes with tape? Or leave them open so that the Carbon dioxide I breathe out can be let out and wont react with the H2S?
