Customer Reviews

Effective but some flaws
First off: the first unit I received was defective but as usual Amazon's customer service was outstanding. The replacement is fine and is actively removing gallons of water from my basement. I saved the price of the pump model by routing the water drain to the water pump connected to my gas furnace and that works fine too.
The product has some shortcomings though. First, the fan is quite loud. Don't even consider using this in a living space. Second, the fan runs all the time, even when the set humidity level is reached. That may be necessary to maintain and accurate measurement of the ambiant humidity but it's wasteful and noisy. The auto-on/off timer is useless because it only allows to set the start time OR the stop time and it has to be reset every time. A more useful feature would have allowed me to set the unit to start at 8 PM every night and stop at 8 AM the next morning for example. Lastly, the drain tubing included is way too short so plan on buying some extra.

Great dehumidifier
I have read the other reviews and do not agree. The unit is relatively quiet for a dehumidifier. It has a fan and a compressor that is needed to be able to take water from the air--that in itself, would make some noise, but it is not a disturbing sound. The room's temperature is shown in the control panel window. You set the humidity that you want, and the machine will run until that humidity is reached. There are 3 fan settings and an automatic defrost. Dehumidifiers are usually used when the air is warmer and humid. In this situation, there is no need for defrosting. However, when the air temperature cools, dehumidifiers tend to freeze up. This one automatically warms slightly to defrost the coils that would normally be used to condense the moisture in the air. Apparently one of the previous reviewers has not recently been in the market for a dehumidifier. They are sold as a capacity quantity machine. The amount of water listed is the water removed in a 24-hour period of time. A machine that removes 40 pints would do that in 24 hours. If the machine was to hold 40 pints of water, it would need a water container that would be the size of a 5-gallon spackle bucket. It has a smaller drawer on the side if you want to empty the water on your own. This machine also has a great pump system. You put the included hose into a hole in the front of the dehumidifier and put the other end of the hose in a drain, out a tiny space by a window, through a little hole by a door edge, etc. You never have to remember to empty the bucket. The dehumidifier in the pump mode can pump the water up 13 feet. The hose is about 16 feet long which for my use is plenty long enough. It can pump up to a sink or up to a basement window. You can go on vacation and not come home to a musty smelling area. The machine is attractive with very plain curved edges. It has casters that roll easily on a carpet as well as a smooth floor. It also has a turbo switch which, when pressed, allows the dehumidifier to run all of the time and continue to remove moisture from the air without regard to the humidity that you set manually. I would recommend this machine without any reservations. It does what a dehumidifier is supposed to do and more.

So far, so good
This unit is working well so far. Time will tell, but it doesn't ice up even during continuous operation. This is used in a basement to reduce moisture in the summer months. I had to by a longer drain hose at the local home improvement store to run the water to a floor drain. A plug is included for the collection bucket, which is nice, as I move this unit from room to room and the floor drain is not always accessible. I really don't use any of the electronic features, I just set it to continuous run and let it go. What I'm really looking for is for it to LAST. The previous unit I had (a Kenmore) only lasted 1.5 years.
