The air drier is supposed to self rejuvenate. Dries incoming air. Releases the moisture to the air as it discharges. No need to replace the desiccant AFAIK.
Even if the dessicant self rejuvenates, I'd like to swap out the two filter pieces for clean ones. As long as I've got the unit on the bench...
