Most of our readers are probably suffering from the adverse effects of winter's cold and dry air right now (see our humidifier roundup). But conversely, there's one thing that anyone living in a humid environment will appreciate: a good dehumidifier. It's always surprising to discover the amount of moisture that can be extracted from ambient air, and these machines will keep your basements and apartments smelling clean. Frigidaire FAD704DUD 70 Pint Dehumidifier
This 70-pint dehumidifier is Energy Star-compliant, and will dehumidify any room by 70 pints a day. It can work continually when it is located near a suitable drain. The filter can be washed and it removes both moisture as well as airborne particulates. ($209)
While using your air conditioner to dehumidify isn't the most energy-efficient way, it can save you the cost of buying a new appliance. Most ACs have a built-in dehumidifying function, and they will quickly get rid of the stale and musty odors of your place. This will also make your place somewhat chillier, as we've noticed the temperature drop by 1 to 3 degrees while the dehumidifier was functioning.
