Q: Do these come fairly dust free or could they be run through a Buchner vacuum w/ cheesecloth to clean?

Mine was completely dust-free. I dumped them directly from the container to a muslin bag for my safe.

Q: Is the regeneration temperature really 550°c? other sources that i can find all list 300c (550f) or 315c (599f) as the maximum temperature to use.

Hi, Thank you for your question. The reactivation temperature for our product, 3A Molecular Sieve, is 550°C.
