we have been talking about it for god knows how long but no one has the balls to buy the membrane and actually mount it to a box!!!, until this guy did. must have been like 6 eevblog humidity congresses held up to this point

DavidAlfa:
The balls? Nope, maybe you meant the money.  That thing costs about $150.

thm_w:
He showed the cheap ones are $10-20, but presumably it would take months for it to dehumidify a wet roll of filament.

Seems there is just this one company making them, no cheaper alternatives?

Interesting technology, but leaving excessive O2 around in a closed container will likely cause issues with some materials!!

Best,

Very true, I have many drawers of parts to protect from corrosion.  Reduce moisture but introduce more O2 shall cause more harm than good.
