I thought the idea of using lower temp, and dryer air, resulted in less damage to clothes was interesting too.
I like that it had two lint filters also. Effective lint filtering is no small task when recycling the drying air as both condensing and HP dryers do. Of course what the author may be calling a "lint filter" may actually be the heat exchanger.
Edit: it appears to actually have two lint filters.
