I hear you about keeping the air clear, but wrapping the 703 in plastic would have a definite negative impact on the its effectiveness in the room. You said it though: unless you're beating them with a stick, the amount of fibrous material in the air wouldn't even be measurable...so long as they're made well. You'd have far more risk from other allergens...dust mites, pollen, animal hair...the usual suspects.
