"Bought a few of these as had been using the cheaper folding ones with rubbish elastic for a while. Good fit, pretty comfortable, easy to breathe in and, best of all, my safety glasses have stopped steaming up."
"I have bought quite a few dust masks recently as completely refurbing a flat. The fold flat ones dont seem to last five minutes, these do at least keep going. The downside is they get very hot and sweaty as you work, the upside is they are reliable. They are fairly expensive, but given the ones half the price only last about a day then they are a bargain."
"I wore this over several days while doing a loft job. It performed well and protected me from dust and fibres. My glasses did steam a little but not excessively - the trick is to breath through your mouth. I would imagine that this would not be a suitable item for everyone, the shape of your face would be a factor in how it works. I got mine for £1.99, but even for £3.99 it would be good value."
