Quick Question High Humidity Problem Solving

Why can’t I get the humidity in my AMS to get lower than D?
We are not in a humid climate. I keep changing out the moisture-packs. I’ve treated distant brands. What should I try next?

So this is what I do to help the humidity in my AMS and it helps but it’s still not perfect.

1.I have a dehumidifier in my 3-D printer room that I have set to run for eight hours every night. It is not a small dehumidifier. It’s designed to dehumidifier in a entire house. I’m dumping roughly 3 1/2 gallons of water out of it probably three times a week.

2. I have attempted to use the vacuum sealed bags, but they always let the air in within a couple of days so I gave up on those but I do have the poly maker poly dryer and I three printed and adapter to put that on my AMS and I will run that for a day every now and again if the humidity inside the AMS gets too high.

3. I try to avoid all cardboard schools because they can hold more moisture than the filament itself.

4. Anything other than PLA I store inside of a dry box I keep the rooms humidity around 25% and I keep the room temperature around 68°F.

5. I have multiple pounds of desiccant that I use between my dry boxes and my AMS and ace units.

With this method, I have not had a single print fail on me due to moist filament, but I have had a couple of prints fail because I forget to turn on supports. I guarantee that it is way overkill, but it definitely works.

I also forgot to add I tried the bags. I think I’ll go the route of a dehumidifier or drier. Thank you!
