further review of this mask now ive tried this mask on many times now my neighbour wanted me to order one and hes used his often now hes liking his as he used it in an enclosed space in a celler until the grinding dust stopped him from grinding as couldnt see a thing he loves the mask my brother has used it as well for the same thing as above he also has a lung problem caused by a cold he likes the mask as there was no way he was coughing his lungs out its also been borrowed by someone much younger and nephew was looking at it as he had his own but liked mine as it didnt interfere with his glasses wearing both younger people liked the mask certainly stopped them having lungs full of dust and coughing them out
