The Cambridge Mask Company has been developing a smart air filtration mask to add to their existing product line. They currently ship a British Military grade mask that filters over 99% of viruses, bacteria and air particulates down to .3 microns. Their next generation mask attaches a bluetooth interface which talks to a connected app.
