I have the reasoning below and I am fairly confident about the direction. I am not… Go to post

Post #2 answers the question as asked. The question underneath it is different.

Visible particulate is a strong signal in the other direction: it is a reason to stop and ask rather than to filter and proceed.

On published stability data actually covers the community has more anecdote than the confidence in this thread implies, and I include my own contribution in that.
