I Googled it and found nothing advantageous over a normal facemask.

How good a facemask is, is just a function of the filter used.
You can't make sweeping statements without qualifying it first.

In a nutshell, an electric face mask (weird name) provides positive pressure inside the mask to make breathing easier.

For most people, they'll do fine using conventional filter masks. But for some people who may have respiratory issues or have difficulty breathing, will benefit from electric face masks.
