I have ordered another filter just in case that helps, but it has not arrived yet. This had so much fine dust despite long rinses, being a fairly recent sheng, and in a form factor that I assumed would be cleaner than average. I filtered it 3x, and it still has a gross layer of visible floating dust. I can’t pay attention to the flavors or scents because I am thinking about the dust. :T I may have to use disposable teabags from now on.
