Pretty sure there's no practical way to get a forced air helmet to work on a bike. Also, maybe it's just me but having anything on my face/mouth while breathing heavily is unpleasant/feels like suffocating and I think best case with a mask I'd be able to commute at a leisurely pace, but would have to save hard rides for indoors on the trainer if my allergies were that bad.
