GIR Silicone Mask Kit Reusable Platinum-grade silicone Kids All-Purpose Face Mask
To stop covid from spreading masks must have no more than .3 microns permiability. Less is better. Is there any way to tell what these masks are?

Hi there! Thanks so much for reaching out. Happy to help! Like the N95 mask, our filters are lab-tested to 99.7% BFE at 0.3 microns and a BFE over 99% for particles at 3.0 microns. Using a GIR filter is vital to our mask’s effectiveness. That's why in each mask kit, we include 5 filters for starters (you can get 10-pack refills from us right here too!). When the filter is used appropriately with a properly fitted mask, it will help fight the spread of COVID-19. We hope this helps!
