Overall, the system is quiet (3 selectable fan speeds for even quieter operation), and does the job well. My only complaint is that while using the hose pump feature, the bucket has filled up, and stopped the system from operating (until the bucket is emptied). This has only happened a couple times since I've owned the machine, so I check it each week and empty the collected water. This would be important for someone who wants to leave the system running for long unattended periods. Someone needs to check the system and empty the bucket IF you're using the hose pump feature.
