Hill 4 pump with dryer question

I have a Hill Mk 3 pump and the intake filter dryer and never had any moisture in my guns. I am in the south where we have high humidity. I only pump up gun indoors in air conditioned space. When done I put filter in a quart freezer bag and get all the air out of it so no asorbison of moisture out of air when not in use. If you have a drier on the high side that is a lot of cubic inches to fill up and would significantly increase the space to fill with a pump and that is a lot of extra work in my opinion.I done this until I got my CF tank a couple years ago. Hope this helps. MM
