I'm presently focused on desiccants that are non reactive with acetone, but absorb water, are easy to regenerate and inexpensive.

Currently I'm looking at Magnesium Sulfate (Epsom Salts) and Calcium Sulfate (Drierite). I don't have any Drierite on hand but I do have Epsom Salts.

I put together a chamber with a DHT11 sensor to test the effectiveness of drying breath samples in real time.  I'll update this project with my results, along with pictures and video.
