Where masks are not required for PPE or medical use, reusable, washable masks represent a significant improvement over single use disposable masks. It's impossible to imagine how many single use masks have ended up in landfill over the course of the pandemic - this could have been greatly reduced if more reusable masks were worn. 90% of the materials in these masks are made from natural and comfortable cotton, with an antibacterial material and elastane making up the other 10%. These masks can be handwashed and reused many times.
