This model (pp600) says it handles up to 7000 sq ft, so can you explain why you recommend the pp650?
The ZX6000 by AirVac is rated for homes up to 7,500 sq ft. The PP650 is the only model to meet this square footage. If your home is 3,500 sq ft, you either the PP500 or PP600, however, you may notice a difference in suction compared to your ZX6000.
