How long before pet hair/dander is no longer an allergy triggering menace?

I recently purchased some used furniture to stage a condo I'm selling. I intended to get only items that were from a pet-free home, but it turns out there's some very old (7+ years) pet hair in this otherwise well-kept couch. I've vacuumed it, but should I still be worried about dander that old being an allergen to potential home buyers? Or does the dander disintegrate enough over time that it's no longer a problem?

    A good vacuuming should be sufficient. Pet allergies are less severe than dangerous ones like peanuts or shellfish and most people limit the time they spend sitting on couches when attending an open house. Anyone napping face down at one, deserves some congestion.
