Which molecular sieve size is best for water absorption? Are any of the molecular sieves able to be reactivated in a typical house oven?

13X molecular sieve is best for liquid water absorption. All types of molecular sieve have to be baked at 550℃/1022℉ to be fully reactivated. If you use a house oven, the molecular sieve can be reactivated at some level, but not fully reactivated.

Are these 4A beads pre-activated or do I have to bake them before use?

They come activated! They work great!
