I think it’s finally time for a dryer box. Want something I can run filament out of directly to the printer. Right now considering space pi vs. Esun vs. Eibos. Ideally something I could run for just a little while before a print and during the print. Low noise also important. A decible chart for dryers would be nice if that exists. Any favorites or good ones I am not considering?

I have the Sunlu one, the OG one without the fan. It seems to work fine. It is silent… because it has no fan. I run it with its lid propped slightly open, about 1/8". Otherwise I figure any moisture cooked out doesn’t really have anywhere to go.
I jiggered it to feed directly into my printer, which involved drilling a hole in the lid and threading in one of those press-to-unlock tube fittings and some Capricorn tubing. It wasn’t too difficult, not least of which because my current Qidi printer would normally accept filament feed via Capricorn tubing anyway, but from its dumb rear-mounted spool holder thingy.
I use this one too. There’s a print that you can use to feed the filament through and it props up the lid but to be honest the print itself is a nightmare to get working right.

Interesting. I hadn’t considered going old school fanless. Do you think the fans are mostly just hype and unnecessary? I don’t understand why the fan ones are so noisy. There are very quite powerful fans available
I found this chart and am leaning toward the eibos more based on this:
I didn’t realize that so many filament dryers exist. I have the Sunlu S2 and it’s working great for me
I just use the cheapest fruit dehydrator and snips away some of the trays.
I got the EIBOS one on Amazon. Not sure it is that different from the Sunlu and others that have been mentioned but it works fine for me. I had a very humid house, lile 60%+ in the summer. I had a lot of problems with petg and even pla before I got that box and none after. We just moved and new house is thankfully normal humidity, but I’m still using it
As an update I found a 20usd coupon for the grakit firefly. According to the chart I posted earlier it’s lower on noise and has aggressive heating / drying properties. Will post an update here at some point for posterity.
I’m away now, so I can’t find sources. I just modified a good sealing container with 1.25" dowel across the middle that holds 4 rolls high in the box. Cut holes and printed fittings for the pneumatic tube fittings. Put silica litter in the bottom. Now I have 4 rolls in a dry box, cheap, that each have their own port at the top of my printer. I’d recommend, though, trying to put each roll on its own roller, as that’s kind of a pain.
I use this: https://www.printables.com/model/791177-cereal-box-style-dry-box-spool-holder-no-hole-cutt Works great, cheap and it’s my design.
Great design, but thats not dryer, thats dry box
It doesn’t fit all the criteria you mentioned, but if you don’t print that much and wanna try a dryer before buying anything, you can make a cardboard foil tent for your printer bed and use that https://m.youtube.com/watch?v=MflrcqNozqs
