## Questions & Answers

**Q: If they are 90% chance this is made in china how can we know the plastic is bpa free?**
A: 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?**
A: Yes, the twin bubble airlock can be removed from the bung.

**Q: what is the height of these from top to bottom?**
A: 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?**
A: Yes. The universal bungs that come with the twin bubble airlocks are designed for 3, 5 & 6 gallon glass carboys.
