Yeah, polyester/nylon/polypropylene are everywhere. There are some really good, reasonably priced all wool ones available here: https://hookandloom.com/browse/undyed-natural-wool-rugs/loom...

They’re so much nicer than the plastic type, and seem durable so far (the thick flat weave type has been holding up well on our stairs).

Unless you have kids or pets, or live somewhere especially humid, in which case you will regret not getting nylon.

We live somewhere humid and have very young kids, their playroom is covered with a very big one of those loom hooked ones, it’s awesome for that because it’s so soft. Spills tends to come out of it pretty easily, the wool seems to be at least mildly hydrophobic.

Polypropylene is probably the least nasty of the bunch.

Probably.

When the BPA scare came I saw so many people switching to a different kind of plastic instead of stainless steel or glass. I just could not understand what people were thinking.

carpets also have PFAS
