Well carbon filters do work very well,,,,,but every bit of air gets passed through them.
A carbon suit would have to cover “every” square inch of skin to do the same thing.
Carbon filters can not be reactivated,,once a set level of air had been passed though them,their history.
The carbon suit people thought they would catch some folks “which they did” they didn’t think that they would get sued by those same folks once those folks realised they’d been had,,,which they have been.
Heck,,,if this stuff really worked “every drug courier and every terrorist in town would be shipping their rubbish wrapped in the stuff,,,which they ain’t.
Some people just deserve what they get:lol:.
