I don't know a lot about Frigidaire dryers, so please forgive my ignorance. Is anyone familiar with the model that "needs no plumbing or venting"? Is this a condenser dryer?
Yes, that would be the Filtrator condenser dryer--they had a little condenser-tube module that slid out like a drawer in front, and it had a drip pan underneath that collected the condensed moisture.
I believe by this time, the Filtrator was in its final run, and Frigidaire was leaning toward doing the normal-style, vented dryers we're familiar with nowadays (which they referred to as the "Flowing Heat" dryer).
