Love the masks… Snug fit, stays in place as I work in confined spaces..ie: under floors and in attics doing pest control clean up services for nuisance wildlife and mice….product holds up well to high dust environments as in confined spaces… Will not go to the job site with out it . Have used cartridge style units in the past but found they restrict heavy breathing when under a heavy work load.. The neoprene masks allow freedom of movement and allow workers to breathe normal. Again….. Love the product.respectfully .. Captain Robert MacDonald, Canadian wildlife control services.

The FB-1 mask with the chemical/particle filter is literally a lifesaver. I work in a boiler shop as a code welder and have for 38 years. The continual exposure to toxic welding gases has impacted my health and the quality of my lungs. Thanks to your masks and filters I not only am able to continue full time employment but have also preserved my health. It was my doctor who originally gave me a catalog with your products and told me it would be the difference between a full life or an early retirement due to decreasing health. Thank you for a wonderful product and I am living proof of the effectiveness of it’s protective qualities.

I purchased this mask to use for vehicle extrication as a solution to the big bulky dust masks that we carried on our rescue. This product has not failed me yet and is much easier to use than dust masks since it uses a velcro strap making it easy to put on without having to remove your helmet and also with a gloved hand. The product creates a nice tight seal around my face and does not allow any of the glass dust to enter. It has also stood up very well to the rigorous tests of being in my bunker gear pockets. I would recommend this product to anyone. It is hands down on of the best products I have ever used

My mask, the FB-1 is a good mask, with a few caveats. Although, this can just be due to the shape of my head. The sizing guide seems to be a little off. I fit the criteria for XL, but the strap seems a bit large? The mask fits good. Except I have a thin nose and I am constantly adjusting the metal clip to prevent my glasses or face shield from fogging up. Sometimes I can still smell exhaust. I am guessing that is normal though. I think I will try to add a piece of foam to the nose area. That might work to prevent fogging. Actually, due to my face size (or abnormality) I may try to add a strip of foam around the mask to improve the seal. These are not complaints or negatives. It is a good mask, and Respro is good to do business with. When I commented the metal clip broke, they sent a replacement ASAP! Maybe a different mask with a plastic self-adjusting clip may work.
