Q: If they are 90% chance this is made in china how can we know the plastic is bpa free?

Don't see that it matters. Nothing passes through the device into the carboy and positive to static neutral pressure inside prevents air from entering. Zero contact means no chance of transfer.

Q: Can the airlock be removed from the bung and used with other standard bungs?

Yes, the twin bubble airlock can be removed from the bung.

Q: what is the height of these from top to bottom?

aloha it is 7 inches.Try making "mead" it is amazingly good even with regular yeast! Add raisins

Q: Will this fit my 5 gallon class jug?

Yes. The universal bungs that come with the twin bubble airlocks are designed for 3, 5 & 6 gallon glass carboys.
