Just as ordinary mask like all other pollution mask, only straps are made to wear around ear and straps are pest together with the mask not stappled. The one I received, came with a faulty exhale valve, colour of product were white, doesn't look like washable like all other mask. For rating purpose can't mention name of other product brand in order to compare. This mask looks almost exactly same as my previous mask. I was using 3m 9504 INV.
