A little trouble with my beads

[Mister]

I've been smoking for a little over a year now. I've since invested in a roughly 100ct humi and some beads from Heartfelt. My beads are in a prefab aluminum block (Heartfelt's Medium 70% Stainless Humidifier). However tonight I was moving my small stock of sticks around and recharging my beads when I noticed RUST! I can see three beads inside the block that are copper colored and there was a small amount of rust on the side of the blocks casing.

Now I'm, pretty sure I'm looking at a new humidification element with this problem. But my question how worried should I be about it being in there with my sticks. Currently I have only just over a dozen sticks in there that have been in with the rusty element. However as of tomorrow I expect to take delivary of a rather sizeable order from Famous and am terrified to put them in there. Complicating matters is the fact that heartfelt is closed thru next Wed (so I can't contact them) and I'm going out of town this weekend and not back until Tues.

I need advice gents!
