Not all blue disposable masks are the same that's for sure! We are delighted to be able to supply a mask manufactured in the UK in Wales to be precise. That's a big deal, it means they're greener, provide local employment and just makes sense as the price is still great. The masks are very well made, they fit snuggly, have a cottony feel and great filtering credentials. See below for the tech/spec stuff! They are sold into the NHS so tick all the boxes. Finally although their made in Wales, they wont improve you singing!
