Hydrogen Sulphide with Gas mask set up

[Qimaster]

I'm looking to do the Hydrogen sulphide method but with some kind of gas mask.

I looked online and couldn't find any masks that came with 2L or 1L containers. They usually only include an Oxygen mask with a tube. If anyone can find relatively cheap one's please reply or PM.

If not, is there a way to DIY one at home? Or are there 2L containers that you can attach a tube to?

I only found one other person considering this on Sasu. Has anyone tried this before?

As per pph it's a painful method though. Please reconsider.
