I love my mask & F3 filers

F3 Filter
Other than the looks I get from people who see me wearing the mask it appears to work as advertised. Is it actually keeping me free from small particles of dust? Who really knows? Does it work better than an N95 against COVID? Again, as long as I do not test positive or do not get some type of lung disease then I have to assume it works. I have the mask with the two straps, and it fits tight enough. I can breathe okay through the mask, and I wear it for 5 or more hours straight when I am doing wood working. So, it has to be comfortable.

Best filters yet.
The slight trop to the jaw on these filters make for a better hug to the face. The foam nose pad is still kinda flimsy for me however, as when I do get hot, my body heat ends up melting the glue holding it down. works fine still after.

New style for Me
Haven't used it yet

Clean breathing
Thanks so much for these filters. The RZ filter system with mask is top notch. I use them in my wood shop all the time I’m cutting and sanding.
