Question: how good are these filters for very,very fine dust particles,like talcum powder fine dust?
Document: Extra filters for our respirators. Lots of forest fires this year and it is always good to have extra filters in case we need them.
I have been doing some dusty renovation work and these filters have performed very well. Even after multiple uses, the filters still enable smooth breathing. These fit on the 7503 3M face mask.
Good P-100 filter that will allow us to go through wet decontamination. As Disaster Site Workers, this allows us to continue to use the filter for its full life without being destroyed by rinse-down
Bought this along with 6000 series half masked respirator by 3M. Used it indoors and out when light drizzle. Haven't had it long enough to know when filter finishes but suspect will last a long time. My influence was the YouTube video that showed this filter versus others...here's link:[...]I believed in buying a better filter than mask, since that is the core of unit. Price point was good too and have 2 spares to replace when need.
No complaints, worked as needed. Arrived fast and secure. Not sure how to tell when to replace but will figure it out.
Looked at every store in our area for these and then found them here! My husband is very pleased with the product
Just get the 6300 Half Facepiece Respirator and these. Nuff said. I use them everyday for pest control backpack spraying. They more than get the job done, and the combination of these two products, you will find, is the cheapest way to go. And, P100 is more than sufficient for most filtering.
Answer: no
