Ease of use

Drainage issues. With three water removal options and "effortless humidity control," editors of say the Frigidaire 70-Pint Dehumidifier FAD704DUD couldn't be easier to use. A full-tank alert lets you know when it's time to empty the unit. Because it will restart automatically after a power failure, one Amazon reviewer says it can be used in an unoccupied home with little monitoring.

Some owners complain that the drain hose is difficult to use. If the unit isn't set to continuous-operation mode, it's not possible to hook up the drain hose to a sump pump or floor drain. One owner remedied this problem by removing the tank, putting a plug in the drain hole leading to the tank and propping the unit up so water feeds to the drain hose. Other users have similar complaints, saying the drain hose doesn't function well at all. However, a few owners say they contacted Frigidaire and received a free Continuous Drain Kit EA155D that solves the problem.
