Quality Filter
Going on a year now, and just thinking it might need replacing. It’s been a solid product. Still going, but the flower garden could use a fresh one for good measure.

Got his after getting a centauri Carbon 3d printer and reading about possible micro plastics and VOC's in the air , read having a window open wasn't sufficient, so for my peace of mind got this. Seems to be working , hard to tell. Can't smell the machine now so must be doing something
