"Apparently, some study showed that if you’ve only got ghastly water to work with, filtering it through about four or five layers of cotton material (like a T-shirt) will strain out a lot of objectionable"

I have 8,000 coffee filters in storage for that purpose. Then after filtering, of course, I will boil it.

Agreed.
I think the mention of the T-shirt straining was a “worst case scenario”
option.
If a fire couldn’t be built, I’d go for trying to build a solar still
or “recycling” bodily fluids before I’d try the T-shirt straining method.
It’s a last, totally-desperate option, for sure.
