As a woodworker in sometimes hot weather I had a difficult time wearing a mask until now! Of all the masks I’ve tried this is light weight, doesn’t fog up my glasses and the nose piece is adjustable. I also like the single strap behind the neck and find it easy to breath with the two vents. The only minor complaint is the bridge of my nose hurts at times but think that’s me putting it on too tight or the nose adjustment was changed from being careless. I’ve tried several masks and this is the best!I can not handle the dust from sanding in the least. This fits comfortable and perfect saving me from total misery. No issue with the nose piece or face fit non breathing.The title of my review says it all. I've had 2 other masks (with 2 straps) that I would wear sometimes while woodworking. With this one I wear it ALL THE TIME because it doesn't interfere/interact with the hat and Bluetooth headphones that I'm always wearing while I'm in the workshop. I figure the best mask is the one I'll actually wear.Just used it a few times so far but seems very good. Well made, comfortable. larger size than I first thought is a good fit but that is subjectiveKept Playa dust out of my nose and mouth really well except in the dust storms. Heavier duty better for those conditions.Super easy to wear in my workshop, even on hot summer days. Does not interfere with hearing protection, Keeping that sawdust out of my lungs.Super easy and efficient - no excuse for not taking your health serious with this easy to use mask!Lightweight and adjustable...fits tightly where it needs to...no open pockets on face.. extra filter included... would buy againFits great with a little gap at the bottom. I have a 4inch nose to chin. So if I was to buy again I would go for a size down. Medium down to small, and also easy to replace the filter. Way better then a normal respirator.Fogs up your glasses, so uselessdoes what it says on the tinUnderwhelmed. Sizing is on the smaller side. Definitely go with a size larger than what the guide recommends.Construction is very good, we'll put together. The included storage bags isn't totally garbage.Definitely not CSA approved, should only be regarded as a dust mask. The manual says it doesn't protect against Silica dust either.I bought to try and filter sawdust.I have COPD and tried using the mask with my oxygen nose piece and air line. This probably let sawdust come in where the line went under the mask. I will have to try again without my oxygen line. I also use a full faced 3M respirator with my oxygen line and it does work well.
