"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."
"For a disposable mask it can get a bit pricey but these really are great quality masks. Good, simple adjustment to create a nice seal. less restrictive for breathing than some other masks and despite working in black dust for several hours I was well protected by the mask so no coughing, choking or dirty snot that you get with no mask or cheap masks."
"These are good value and appear to be pretty free flowing (ie the valve works well and the material lets air in easily). They also feel more robust than others I use (eg 3M Aura). However the shape around the face is fixed and not mouldable (ie fairly rigid plastic mesh and no bendable metal strips) , so if it doesn't fit you face you will get gaps. For that reason they are not for me....."
"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."
