Full Face Respirator Acid Gas Safety Respirator Filter(2PS LDY7 Filter Cartridges)

Thickness I can see for the filters to fit in masks, but sheerness? These took forever, and are unjustifiably expensive, but the only ones available.

April 10th. Yeah, I finally got the filters after bitching, complaining, and threatening since I ordered them on March 19th. And this is before the big scare of the virus and the run of the N95 cotton masks........

works great

Received exactly what I needed in a quick manner.

Works great for smoke from fires

Did not fit. Just slightly too large and I can't return as I open the one package to try the size.
