3MSafety 142-7503 7500 Series Reusable Half Face Mask Respirator, Dark Blue, Large

3m quality / works with a large variety of filters. One of the best

The plastic frame that attaches to the soft rubber face cover popped off of mine a bit too easily. It did snap back on thankfully. I bought the large. My face is normal but they seem to be most comfortable. If you have a small face don't get the large. These were a bit less than the ones sold from others..probably because, as I understand it, they (Chinese or whoever) are licensed to make and sell same specs. I followed other reviews which confirmed that they were 3M specs.The straps on this model are more comfortable and sturdier than the other models. I recommend this seller and this model.

I used this mask along with the appropriate filters to paint and clearcoat my Wife's rear bumper cover. I'm still alive and breathing.....

It makes an excellent seal, no too tight as there is sufficient cushion area to makr the seal comfortable. When worn with the canisters it does draw attention in stores, but I wear this mask for my protection. This mask with some biker glasses or goggles makes you about as safe as you can hope to get from viral exposure, not 100%, but I would gues 70% or better.

Sanded my hard wood floors and this was a life saver

Does the job.

Most comfortable mask I have owned!

Arrived without any of the exhilation valves. Appears to be new but missing parts. Unsafe to use it without the valves. Incomplete package
