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 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

I found this chart and am leaning toward the eibos more based on this:

I just use the cheapest fruit dehydrator and snips away some of the trays.

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
