Delonghi Energy Star 45 Pint Dehumidifier

DeLonghi is one of the leading manufacturers of home appliances in the world, and this particular DeLonghi dehumidifier, the Delonghi Energy Star 45 Pint Dehumidifier, is one of the most popular medium-size home dehumidifiers made by DeLonghi and one of the Best Whole House Dehumidifier.

Ease of Use

The ease of use combined with ease of maintenance makes this DeLonghi unit one of the best dehumidifiers for those looking for a ‘set and forget’ dehumidifying solution.

However, users can still control the amount of interaction they have with the unit, with two options of water collection: via the novel patented pump and hose, or by merely emptying the internal tank as required.

How much electricity does a dehumidifier use is not a problem with this Dehumidifier. You will save tons of energy during the year.

Simple Rinse

Periodical cleaning of any dehumidifier is necessary, but the Energy Star makes this as easy as possible with just a simple rinse of the air filter required. This is typical of a Best Whole House Dehumidifier.


The DeLonghi 45-Pint Energy Star Dehumidifier has:

  • LCD display and electronic controls for easy access to critical statistics
  • Automatic water emptying via active pump function
  • 24-hour timer for ‘set and forget’ dehumidifying
  • Humidistat for custom setting of your perfect humidity level
  • Energy Star certification for impressive savings off your energy bills


Patented Pump

This DeLonghi Dehumidifier, the Energy Star, is the best dehumidifier in the 45-pint size mainly due to one particular function that sets it far above its competitors, so much so that DeLonghi have patented it so that other companies cannot copy them.

This is, of course, the pump, which actively pumps water out of the dehumidifier and out through the hose. This automatic removal of water collected by the dehumidifier unit is the ideal feature for anyone who wants the effortless removal of moisture from the air. Another aspect of a Best Whole House Dehumidifier.


As you can probably tell from many dehumidifier reviews, there is nothing more irritating than having to regularly empty buckets of water. Dehumidifiers are supposed to make life easier, not add to the daily chores.

I could not agree more with one customer who states her disbelief as to how all dehumidifiers haven’t had automatic pumps up until this little DeLonghi dehumidifier.

Best Whole House DehumidifierThe Energy Star DeLonghi Dehumidifier appears to be quite popular among those who own flooded houses, some Energy Star dehumidifier reviews being from customers whose homes flooded unfortunately as a result of hurricanes.

If you have a big bathroom this can be your best dehumidifier for bathroom.



Such extreme levels of moisture would be the ultimate test of this unit’s abilities or lack thereof. Sure, I have tested the unit thoroughly but not with any moisture that could compete with that left in the aftermath of severe flooding.

Best Whole House Dehumidifier can Dry Out Fast

It is, therefore, very pleasing to hear that the Energy Star DeLonghi Dehumidifier can dry these rooms out in a reasonable amount of time.

While the capacity may be 45 pints per day as opposed to larger dehumidifiers that can remove up to 70 pints per day, the patented pump which enables automatic drainage means that you can literally leave this DeLonghi Dehumidifier to run 24/7 without having to interact with it at all, except perhaps to rinse the filter every now and again.

This automation is the key for busy modern folks who don’t have the time to be emptying buckets every day. Running any appliance 24/7 is a worry for many, but the Energy Star DeLonghi Dehumidifier can handle it.

I would only suggest giving it a rest maybe once a month. Moreover, reviews from customers who have owned this unit for extended time periods indicate that it is not prone to break after a short time in use, as some lesser quality home appliances may do.

On to the negative points that customers have raised. Some owners have written that the Energy Star DeLonghi Dehumidifier is quite loud, and while it is true that compared to a toaster. For example, the Energy Star is loud, concerning all the other dehumidifiers we have tested, it’s average.

The main issue that customers complain about is the timer feature and the fact that if you want to change the times at which the unit switches on and off, you have to set it each day, rather than pre-set it all beforehand.


DeLonghi could have made a perfect product if they had just made these adjustments. However, I maintain that the real strength of this dehumidifier is its ability to run 24/7 with no breaking and no need to empty it. In this case, you don’t need to program anything. To sum up, this is one of the best Best Whole House Dehumidifier.
