I would like to see analysis of microplastics from water filters.

Water filters frequently use a very fine plastic mesh as their filter medium (eg. 'melt blown 5um polypropylene sediment filter'). I would expect that to give off a rather large number of particles the first time water is passed through it, and perhaps a good amount on an ongoing basis too since the mesh will flex with varying water flow.

Since people wanting to avoid pollution are likely to have water filters installed, it seems important to know how much pollution they are adding to the water they are trying to clean.

That is just 1 reason why it's a good idea to distill your water.

Many DIY examples I’ve seen use an inverted pot lid over a bowl (which is inside the pot) to collect steam into distilled water.

The lid handle is invariably made of plastic.

"Invariably" is way too strong of a word here; the two lids in my kitchen both have steel handles.

How do you get minerals back? And where do they come from?
