DeLonghi DD50P Energy Star Dehumidifier Review

The DeLonghi DD50P Energy Star Dehumidifier is a medium to large capacity unit that is capable of extracting 50 pints of water every day with its internal condensate pumps. It has a low temperature operation which allows it to work in basements with temperatures as low as 41°F (5°C). The DeLonghi DD50P is cooled by using the R410A refrigerant, an environmentally ozone friendly refrigerant gas that has a very low toxic level.

The DeLonghi DD50P comes with a digital LCD display to make it easy to use and navigate. It has adjustable humidity levels ranging from 35-90% to suit your own humidity preference. The unit comes with a washable air filter, two fan speeds to choose from, a thermostat regulator so as to ensure a constant temperature around your room.

The DeLonghi DD50P is also energy star-qualified, which means that you can save between 10 to 20% less energy than other non-certified products in its category. It also has a 24-hour programmable timer so that it can automatically shut off after a while of use.

The DeLonghi 50 pint Dehumidifier features an auto-defrost function. Because water vapor is removed from the air by condensing it onto cold coils, ice can accumulate on these coils at temperatures, from 65°F or lower. The formation of this ice can damage the unit, so the auto-defrost system stops the compressor to allow the flow of air to melt the ice. So as you can imagine the cooler it gets, the more time it spends defrosting and thereby the less effective it becomes.

So even though this DeLonghi dehumidifier can operate safely at temperatures as low as 41°F, it cannot be considered an ideal choice for cool areas that remain below 60°F, for extended periods of time.

Despite the DeLonghi DD50P 50 Pint Energy Star Dehumidifier weighing 41 lbs, it’s very portable because it is installed with caster wheels, making it easy to slide around your home or basement.
