Creating a mask with flexible edges that can be adjusted to fit the vast majority of faces is not a difficult problem---several different manufacturers have solved it.
They just don't bother with the cheap disposable N95 masks. Even for those they don't 'tailor' masks to fit individuals---they just have people try on a couple different brands.
From what I've heard fit tests as conducted in US hospitals are literally just 'spray some solution and ask if the person can taste it'. If you can feel the suction of the mask on your face when you breathe that's a good indicator it fits well enough.
Also, the internal fans might mitigate issues with fit, depending on how they're set up (blowing away air from areas other than the filters).
There's going to be another drop today at 11 PM EST... think I'll try to snag one. Last time apparently the site crashed almost immediately and when it came back online they were sold out.
[edit: fit test uses taste, not smell
also:
'TWO-SPEED DUAL INTAKE FANS
The chambers allow freshly filtered air to flow freely so you can breathe comfortably. For active users or those that prefer more air circulation, toggle the fans between 2 adjustable high-speed modes (4200/6200 RPM) via the multifunction button.
SOFT SILICONE FACE SEAL AND DUAL STRAP DESIGN
Ensures a tight seal over your mouth and nose while providing a secure, yet comfortable fit for all head sizes.']
