Exactly, that's why I've been using and recommend the orange stuff from the person in Singapore. At this point though I am highly impressed with the Eva Dry. The bags are .4 cubic feet when fully expanded and generally I push most of the air out so they're really more like .2 cubic feet. The Eva Dry is rated for many times that volume and it shows in drying times. I don't have to leave filament in over night with the Eva Dry to tune it back up. I can pop it in for an hour and get a nice razor clean print from it.
At this point I've purchased another of the Eva Dry's from Amazon so I can keep my filament razor sharp ready for my farm.

One Ziploc Big Bag Large size
One 50 gram pack of orange indicating desiccant
Phillips #0 screw driver
Poke holes in the desiccant pack with a Phillips #0 screw driver. I suggest six to eight holes spread evenly over the top of the pack.
Place spools in Ziploc bag and place desiccant pack on top, seal bag. I find over night in a heated place is enough to dry out PLA to be printable again.
When beads in the pack turn green it is time to think about replacing it or refreshing it in the oven.

Suggested warm place: top of your hot water tank. (if your hot water tank isn't water tight you've got bigger issues than damp PLA)
I have now tested this design using an Eva-dry Renewable EDV-300/E-333 Wireless Mini Dehumidifer. This device has a built in dryness indicator so you know when your filament is staying dry and when you need to renew the dehumidifier. The device has a built in drier that allows you to plug it into the wall over night and have it dry itself out. Device is rated to absorb up to a cup of water.
The Ziplock Big Bag and Eva Dry can both be purchased from Amazon.
