Those internal battery operated fans are the one significant difference between that rave mask and typical industrial face masks. I have not seen that or heard about it from any reps on the industrial side, and I'm guessing there's a dozen reasons for that, including but not limited to:
Filters and filtration efficiency - The gimmick mask's filters are most likely playskool quality, just look at the size and weight of actual P95 cartridges or even P100 dust filters for comparison. Actual aerosol filters have well-defined service lives, relying on charcoal/carbon for filtration, and making them in miniature (never mind removing the carbon scrubber) would probably render them mostly ineffective. The gimmick mask maker is implying that their little dinky filter elements are worth a shit, which would honestly be a hell of a technological advance - it's also not entirely clear whether the filters are one way or (even more unbelievable for efficiency) two way. I would lay money those filters are dogshit, likely the equivalent of an N95-rated dust mask's fabric, and as soon as they get moisture on them (almost immediately) they won't filter very well at all.
Weight - Considering actual aerosol cartridges weigh a good amount, putting an extra battery and motors into a half-face would be obnoxious. Even when using lightweight P100 particulate filters, adding weight and size isn't something you'd do on purpose. It's simply a functional comfort issue.
Complexity/Cost - Batteries, motors, these aren't things you want to add if you don't need them. How long does the battery even last? How much air do the tiny fans circulate and can they actually keep up with strenuous activity? Can you make an effective 2-way system that doesn't leak? Real masks use one-way valves with the exhaust being unfiltered. Are you gonna throw all that shit out regularly, considering how gross silicone masks get after repeated use? Regular masks are essentially disposable, though they do get reused when the filters are detachable. Etc, etc.
The nicest powered air system is 3M's new generation PAPR (Personal Air-Powered Respirator) but as you said, it uses a full-face helmet and positive pressure to "seal". Hoods are simply more comfortable than face masks, and they also offer eye and skin protection that half-masks don't. They also keep you nice and cool with the air blowing down over your face. I would choose a hood/visor over having a mask clinging to my face any day, that's probably the most unpleasant part of wearing a silicone mask to begin with. 3M systems are about $1800 but they're great. Usually if you work in one specific area it's preferable to just get a clean air line and ditch the belt/battery/fan/filter rig while using the line to power a hood.
If a reputable manufacturer made a powered half/full face mask I'd gladly try it, but for all the reasons listed above and an added healthy dose of plain cynicism, I suspect that this is more of a toy than anything else. Real masks have to work. I'm guessing that thing comes with a big disclaimer about how it's "for recreational purposes" or something. There are legit engineering concerns in making an effective powered half-face and one that was industry-rated would probably cost closer to $500 than $99.
