I see your dilemma and understand well the frustration you're having, but consider the carpeting holds dust and the movement of the dogs stir up the dust in the cpt and put it into the air, and its a constant if you have the dog in the house and the carpets are relatively old and compacted with dust through to the padding. I had it also and removed the cpt and went to hdwd flrs and the dust stopped and I do live on 20 acres and have animals and a pvt gravel road, now the dog doesn't care to come in the house as he slips on the flrs, but boy is it clean...my filters are changed less frequently too. decisions, decisions!!
