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.

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.

【How to Reactivate】: The 3A molecular sieve can be placed in a muffle furnace and backed at 550°C (1020℉) for 2 hours, then transferred to a drying cylinder, and cooled to room temperature for use.
