What is it used for?

Effective protection against the transmission of airborne pathogens.


What's nano about it?

NanoMask uses nanoparticles on the surface of the filter to increase the filtration capabilities of the mask. Nanoparticles have very large surface to volume ratios which makes them excellent filters. The nanoparticles are active for 48 hours when placed in the mask.


How does it work?

Most filters used for medical masks are rates as N-95 which means that the filter is 95% efficient at removing particles with a diameter of 0.3 microns. EFM uses a double filtration system of a hydrophobic and a hydrophilic layer to increase efficiency of the mask. The two layers work together to manage the moisture in the mask which pathogens need for growth. The nanoparticles are negatively and positively charged and they trap and destroy bacteria and viruses. EFM says the filter is 99% efficient at removing particles with a diameter of 0.027 microns. The smaller the size of the particles the more difficult it is to remove. The filter is said to trap and destroy (within 1 minute) the H9N2 Bird Flu Virus.
