Dessicant driers for flawless paint. Best for the money

I'm using the canister type desiccant dryer linked below - it is one of the cheaper ones I could find. It's working great so far, but granted, we don't have the highest humidity levels here in SoCal. I've been running it for about a week for general tool use and running my sandblasting cabinet, and the beads at the very bottom are just starting to turn a little purplish-pink (Mopar content: a little lighter than Plum Crazy but not all the way to Panther Pink). From what I have read, it is recommended to run a particle filter after a desiccant unit to catch any dust or debris that flies off the surface of the beads - so I have a cheapy 1/2" Harbor Freight filter plumbed right after it.
