Why Do You Need a Dehumidifier?

There are two main reasons why you need a dehumidifier. First, the health of your family is important. Dehumidifiers stops allergens and bacteria from triggering allergy and asthma attacks, as well as protect against respiratory issues.

Second, you need to protect your home from mold, mildew, and other bacteria and germs that like to live in hot, humid environments. The high humidity levels also harm your furniture, studs, beams and joists and a dehumidifier protects them as well.

Keeping your house in top shape helps you avoid those high renovation and repair bills that come when the wood and furniture in your home are ruined by high humidity.

Not only can you save money by using an energy efficient dehumidifier, but you can also save money by not paying for expensive repairs.

How to Use a Dehumidifier?

Using a portable dehumidifier is one of the easiest devices you can use in your home. All you need to do is roll it into the right position, away from walls and furniture and other obstacles, punch in your settings and turn it on.

Then, all you have to do is empty the water tank when it gets full. Every couple of weeks you need to clean the air filter and that is about it.

TOSOT 4,500 Sq Ft Energy Star Dehumidifier Review

When you have difficult humidity problems to solve and you have a large room to lower the humidity levels in, this is the model for you. Rated for 4500 square feet, this top energy efficient dehumidifier lets you choose how the moisture will drain away.

You can use the continuous drain function or the 2 gallon water tank. With its quiet motor, 51 decibels, you 8should not be disturbed when it is running. The good news is that it is energy star rated which means it uses 30% power than other dehumidifiers.

Then the built in pump is powerful enough to move that water over 12 foot high walls. A washable filter and other fine features make this the top quiet energy efficient dehumidifier in this round up.

On top of those features you also get auto restart, 50 pint removal in 24 hours and an easy to use control panel that monitors everything, including the fan speed.

TaoTronics Dehumidifier 50 Pints Review

Large rooms and heavy humidity levels are not going to be a problem once you put this unit on the job... Its 4500 square foot rating and 50 pint removal every 24 hours makes sure your larger areas are not bogged down with excess moisture.

A built in humidistat and temperature gauge makes sure this unit delivers optimum temperature and humidity levels and meets your settings easily. Then you can set the timer to start or stop this device when you want it to operate or when you want it to take a rest.

With the pump switch you can ignore emptying the water bucket and have the dehumidifier empty that excess moisture into a sink. But if you choose to use the 1 1/2 gallon water tank, the machine will turn off on its own when the bucket is full.

This dehumidifier should also save you on your energy bill when in use.

What We Liked

  • Pump button to activate pump
  • 24 hour timer
  • Removes 50 pints per day

What We Didn't Like

  • Instruction manual in poor English
  • May be a bit noisy

CLEVAST 1,500 Sq. Ft Energy Star Dehumidifier Review

A little bit smaller in the rating department but this 1500 square foot can clean out between 22 and 30 pints of excess moisture per day. Then it works best in temperatures between 41 and 92 degrees F.

Once in your home, you can enjoy the reusable filter, the power cable holder, the continuous drain function and the 360 degree directional wheels. This compact dehumidifier moves in any direction you need to move it in.

That’s not all. The easy to clean removable water bucket holds almost a gallon of water and shuts off the unit when it is full. All the controls are in easy reach at the top of the unit and one finger is all you need to change its settings.

The timer turns the device on or off at your command and a filter light lets you know when you need to clean it.

What We Liked

  • The 24 hour timer
  • The rotating wheels
  • Its compact size
  • Its overall look

What We Didn't Like

  • Can’t change humidity level on auto mode
  • Very small water tank for the rating
  • Filter not included

AmazonBasics Dehumidifier

Another smaller unit that handles those rooms that do not get too large. With its built-in pump, you should be able to clear your basement, family room and other large rooms in your home without having to use the 2+ gallon water tank.

Then with its auto restart this energy efficient basement dehumidifier starts right up again when the power comes on. No need to head downstairs to turn it back on. On top of that you have an auto shut off function, timer, defrost function and more.

Turn to the easy to use control panel to make your selections and get your home healthier and easier to live in. The approx. 60 decibel motor level is still fairly quiet and keeps the noise down when you need to concentrate on other duties.

Keep in mind that when the rating says 1000 square feet, that rating is done with an 8 foot ceiling in mind. Taller ceilings in your home will have different results.

What We Liked

  • Large water tank
  • Easy to use and maneuver
  • All the features you need
  • Built in pump

What We Didn't Like

  • May be too small for some rooms
  • Clears only 22 pints per day
  • Pump does not start when it is supposed to
  • Hard to remove water tank

GE Appliances Energy Star 49.5 Pint Dehumidifier with Pump Review

When you want a different look to your room, this gray dehumidifier will provide it. The darker color should help the unit blend in and remain invisible for those times you want no one to notice it.

While it is blending in, it removes up to 50 pints of excess moisture per day without batting an eye. Then when its water tank is full, the unit should turn off right away. A 16 foot drain hose is included so you do not have to stop what you are doing to empty that water tank.

In addition, there are LED digital controls that take only a fingertip to manipulate. Once your settings are selected, you should get top performance from this dehumidifier.

A digital readout, timer and defrost controls are also part of the features you get when you purchase this machine. A pump button activates the built in pump for you.

What We Liked

  • Has all the standard features needed
  • Long drain hose included
  • Clear digital display

What We Didn't Like

  • Not very durable
  • Does not last long
  • Thermostat does not work well

What to Look for when Shopping for the best Energy Efficient Dehumidifier

Knowing what to look for in a good energy efficient dehumidifier helps separate the best from the rest of the pack. Here are some tips to guide your search:

  • Cost - it doesn’t have to be expensive to be good or energy efficient. Meet your budget and get the one that is best for your home
  • Features - auto restart, auto shut off, defrost, wheels and built in pumps are all good features to have in your dehumidifier. Also, you should have more than one fan speed, a timer, and digital display for humidity levels and settings.
  • Brand - the maker of the humidifier is actually important. Top brands have a reputation to protect and they strive to bring you the best units possible.
  • Capacity - both the water tank and the excess moisture removal capacities should be high. Small water tanks just give you more work to do and low water removal capacities means your room may not get dehumidified right. Go for the higher numbers here
  • Rating - this does not have to be large to be effective. You only need a dehumidifier that is rated for the square footage of your room or a little bit larger. Too small of a rating means your room will not be dehumidified

What We Found

What we found out during the research portion of this roundup was that to be energy efficient a dehumidifier does not have to be small. All it needs is that energy star certification and you will save money.

Smaller units will still use less power but now you can dehumidify larger rooms without worry or adding a lot to your electric or energy bill. Also, we found out that traditional strong and famous manufacturers and brands do not always put out the best devices for your home.

And the winner is...

When you are looking for the best energy saving dehumidifier on the market, make sure to read all the reviews. We picked the TOSOT Energy Star Dehumidifier as the winner of this roundup for its large capacity, large rating and its features.

Plus, it seemed to be the one with the best reviews. Reviews are important and have helped tip the scales in this unit’s favor. We liked a lot of the included features as well including the large water tank.

The others performed well but were not up to the task of catching up to this model in terms of service and overall appeal.

Whether that dehumidifier removes 30, 50 or 70 pints of moisture per day is not the key issue. You have to have the unit that is rated for the room you are placing it in. Also, you need a water tank capacity large enough to cut down your work load.
