3MReusable Respirator Half Face Mask, Large, 6300

I use this mask mostly when welding and it fits well under my welding mask. I use it with gas cartridges when working with nasty vapours, when painting and cleaning. There are cheaper options, but this unit is solid.

Keeps the harmful particles out of your lungs, make sure you get the proper filters for the job you are doing! Used this with these filters when doing huge renovations to my house. https://www.amazon.ca/gp/product/B00KYX8JBU/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1

This is a terrific respirator, worth way more than it's cost!! Review details toward bottom: My husband Clark Kent, has been mysteriously immune to all illnesses and injuries for his entire life (except those caused by Kryptonite). Therefore, he has always shrugged off personal protective equipment. In fact, it has been almost the ONLY cause of marital fights for over 25 years. Last month he was diagnosed with Sarcoidosis of the lungs and hearts. This is a mysterious illness that causes calcified growths in any organ it strikes. There are few treatments other than steroids and hoping it decides to stop before an organ transplant is necessary. He must ruthlessly protect his lungs from now on. Home improvement enthusiasts everywhere: they don't know what causes Sarcoidosis, but repeated exposures to drywall dust, sawdusts, etc. seem to increase your chances. Don't wait until you are 50 to protect your lungs!! ANYWAY: Clark really likes this respirator! He says it is VERY COMFORTABLE, and he says he is willing to wear it for all dust producing jobs. At the moment, he is wearing a very short goatee and he is still able to get it tightened with a seal. Our two teen sons (both with different face shapes), also tried it on, and were able to get good seals. Clark has a very narrow nose, Son #2 has a wide nose. This tells me me that it is highly adjustable, even if you don't get your size perfect. Son #1 took it to his Gunsmithing class and let them all try it on to figure out their size and they all bought one of their own in either a Med. or Large. (I cleaned it with a disinfectant clothe after!!) Buy one, your lungs will thank you, so will your partner!!

I use this mask with 2 6005 filters a few times a week filling a formaldehyde cattle foot bath. Works great.

I have bought a few of these and I like them. They are light and comfortable to wear. What I don't like is the elastic wears out fairly quickly, but elastic is cheap and I do a replacement when they get soft. Another thing to watch for is the filter elements can come off and you don't know it. I put a little dot of silicone glue to make sure the filter does not come off unexpectedly. Overall, good mask and good price. Oh, be sure to research which filter cartridge you need. I use the 2071 for my wood dust, chicken dust, mowing, etc. If you are into painting or chemicals you will need a different cartridge.
