we're a no cat household, but do have 2 dogs (one black, one white) that are allowed into certain rooms of the house (living room, kitchen and dining when we're not preparing food or eating) and not on furniture. I sew and long arm on different FLOORS of the house than where they are allowed to be--but still I will find those few hairs that float in the air or stick to our clothing or shoes and we carry upstairs on us in the sewing rooms. It's impossible to totally prevent.
