Pros / This Sunpentown dehumidifier is energy efficient. It uses less power than most of the other units on our list and is Energy Star certified.

Cons / The water-collection reservoir holds a small amount of water (14.8 pints) and must be emptied often.

 Verdict / The Sunpentown SD-52PE isn't as large as other home dehumidifiers, but it still removes 50-pints of moisture within a 24-hour period while using substantially less energy.

If you live or work in a humid climate, that excess moisture can do some serious damage to your home's interior. Besides damaging the flooring or walls, that excess moisture is a breeding ground for mold, which can cause a variety of health effects. The Sunpentown SD-52PE home dehumidifier collects up to 50 pints of water per day using very little energy. It is one of the best dehumidifiers we have reviewed and we give it our Top Ten Reviews Bronze Award.

Efficiency & Energy Use

This room dehumidifier lets you set the relative humidity levels in your home in increments of five percent, which is better than most units that only let you change levels in increments of 10 percent. This means you will have greater control over the amount of relative humidity in your home. This unit is capable of removing up to 50 pints of moisture from the air each day from a 1,300-square-foot area. The Sunpentown SD-52PE is a good choice for a bedroom or bathroom. It can also work as a dehumidifier for your whole house, too, if your home is smaller.

It uses about 520 watts of power. This is significantly lower than most of the dehumidifiers we reviewed, in some cases as much as 200 watts less. The Sunpentown dehumidifier is Energy Star certified, meaning it performs its functions using 30 percent less energy than comparable units. The water-collection reservoir holds 14.8 pints. This isn't the smallest capacity of the dehumidifiers we reviewed, but it is smaller than other units, which means you may empty it more than other models.

Another option if you don't want to empty the water bucket is that you can connect a hose that's included with the Sunpentown SD-52PE that attaches to the back of the dehumidifier and continually drains water from the hose. You can opt to rely on gravity to pull the water from the machine so it can empty into a nearby floor drain, or you can use the drain pump.

Comfort & Safety

This dehumidifier comes with some handy features, including a water-level view window so you can eyeball the water level and empty the collection bucket before it gets too full. There is an alert that will go off, too, if you are not close by. This dehumidifier also has an auto shut-off feature that prevents the water bucket from overflowing.

If the air temperature suddenly dips, this Sunpentown dehumidifier will switch to auto defrost mode. This shuts down some internal parts and pulls warmer air into the unit to prevent it from icing over and breaking. Once the internal temperature is safe, the Sunpentown SD-52PE will return to running normally. This is a great, self-maintaining feature.

Design & Dimensions

The digital display panel is where the humidistat is located. It displays the current humidity level in the room and lets you set the desired relative humidity. In addition, you can set a timer so the unit isn't continually running throughout the day when it isn't as hot or humid as, say, other times.

The Sunpentown SD-52PE weighs 40 pounds, which is heavier compared to other 50-pint dehumidifiers. This unit comes with four caster wheels, which makes it easier to move it around.

Warranties & Support

If you need help with your Sunpentown dehumidifier, you can reach support personnel by phone or email. There is also an online version of the user manual that explains how to set the timer and humidistat, remove and clean the air filter, and more.

This dehumidifier comes with a standard one-year warranty on both parts and labor. Unlike the best dehumidifiers on our review, inlcuding the Friedrich D70BP, the Sunpentown SD-52PE doesn't come with an extended warranty on the sealed system, which includes the coils and compressor that are typically expensive to fix.


The capacity and effectiveness of the Sunpentown SD-52PE makes it a good machine for a bedroom, bathroom or small home or office. It includes several self-maintaining and safety features and regulates humidity levels using minimal energy.
