Review on Polyurethane Pollution-Resistant Breathable Materials: Reusable, Sustainable by Narendra Thapa

Revainrating 5 out of 5

Very thin passport material. Doesn't necessarily protect you from anything other than leaf blowers and road dust, but allows you to meet mask requirements and still breathe freely.

Pros
  • Masks and respirators
Cons
  • New competitors have emerged
