The alumina can be regenerated as well.
I am going for the activated alumina because of the different drying profile and it's much more hygroscopic nature. As of now I can't get the humidity low enough from the general humidity of room to be anywhere near the level of dry recommended for TPU and PETG which I am having some issues with.
I think it's just from opening and closing the AMS in a relatively high humidity environment. It stays consistent once it settles but is saturated to green quickly by it.
I don't know if it's that it was cheap and less effective or whatever but my experience has been middling and I'm willing to try something else.
Plus the idea of having the desiccant in a container I can throw directly in the oven to more quickly handle the refresh seems like a better idea than the act of removing the desiccant each time to try and regenerate it.
