Yong Heng blue filter. Desiccant beads?

This may have been covered before but, the Y H compressor came with a cigarette filter at one end and a wafer at the other end of the blue filter. It also came with many replacements.

Is this the designed configuration ? Do people put beads in between ? I have a gold filter in line after lined with a 8 x 10 piece of xray film filled with beads with 3/4 " tampons at either end . No H2O at all in my tank . Just curious .
