Only had this dehumidifer for a very short while, but am amazed at the amount of water it removes from the air.  Have it in the basement and it removes more than 2 gallons of water every 10 hours or so.  Still trying to stabilize the humidity, running in continuous mode for 3 or 4 days per the instructions (am on day 4) and haven't yet started using the pump, which is actually the reason for purchasing this model.  Clearly making a huge difference: no more sweating on the pressure tank for the well water, and the previously damp concrete floor underneath is now dry.  Fairly quiet even on high.  Very solid and well-built.  Am hopeful it lasts a long time and the pump feature works to get the water up and out of the basement (no floor drains, so have to pump up and out a washer drain about 6 feet off the floor).
