Best Dehumidifier for Attic – Your COMPLETE Guide

One of the best features that this unit has is its ability to maintain the humidity at a constant level. 

You can set the desired value and let the dehumidifier run until it reaches that level and keep it constant.

This unit comes with built-in universal wheels, and the handles are ergonomically designed to allow for 360° movement of the unit.

It runs very quietly as well; thus, it will never create any disturbance while you are working at home or sleeping during the night.

Another great feature is that one can press the lock button for 2 seconds to lock the dehumidifier. 

In this way, you don’t have to worry much about your children whom may damage the appliance or worse, get hurt themselves.

It also has continuous water drainage ability - simply connect the unit to the sink. No need to worry about constantly emptying the water tank anymore.

In addition, the air filter for this unit is easily removable and washable.

The only drawback that this unit has is there is not a built-in pump.

If you don’t have access to a floor-level water drain, then you will have to add an extra pump with it to drain the water inside the sink.

#2 Keystone 50-Pint Dehumidifier

Keystone's High-Efficiency dehumidifier is suitable for spaces measuring less than 3000 sq ft.

This unit can extract almost 50 pints of water in 24 hours and its settings allow you to set the dehumidifier at the desired humidity level.

Water collects in the water bucket during the working process, and when the bucket gets full, it gives an alert to shut off the dehumidifier. 

Thus, one can easily empty the bucket and turn it on again.

When the room reaches the desired humidity level, the dehumidifier automatically turns off.

It also gives the filter alert on the display panel when the cleaning of the filter is required.

One con is that this dehumidifier's power consumption is very high.

If you want to use the feature of auto drainage of water, you will have to attach a pump with it.

Moreover, it has no built-in pump which means you will need to empty the tank when it is full.

Among the main features of this dehumidifier, we can find a humidistat that’ll let you know the specific level of humidity in the room, and a timer you can set if you want the device to work for only a certain amount of time.

Moreover, the settings include two different fan speeds, regular and turbo, and a safety auto shut-off option that allows the device to automatically turn off when the bucket is full of water.

The dehumidifier comes with a set of 4 casters, and, since it’s relatively light (it only weights 40 lbs), moving it from room to room won’t be difficult.

Although the price of the unit is a bit on the high side, maintenance costs aren’t too expensive, especially because the filter is washable and can be re-used.
