THEY ARE NO LONGER MAKING THEM!!! WTF!?!@(%#

I've been doing drywall and taping for over 4 years now and have been using this product the whole time. This is by far the best reusable dust respirator out there, especially compared to the paper disposable masks that do nothing but lets in dust or whatever else your working on. For some reason they have decided to stop producing this and have taken them out from all retail stores. I guess now since 3M bought them out or whatever the hell happened, they have completely yanked the rug out of a quality product and now giving us crap. Way to go guys, way to ruin a perfectly awesome product.
