Product review: Gurin Electric Compact Dehumidifier

Add caption

Gurin Dehumidifier is 9" tall and 5.75" wide at the base. Its best feature is that it very quiet because it does not have a compressor, the worst feature is that it is not very effective in removing humidity. Both are not surprising and stem from the technology used in this unit. More on the technology itself at the end of the review, but first a few examples of what I observed in my use of this unit.

1. I originally hoped to use it in the bathroom while it is used for showers to keep the air dry, and to prevent fogging of mirrors. For several day, I turned on the unit each time the shower was taken, and turned off the unit when the shower was over. In that use the humidifier tank remained empty. Thinking back to how the Peltier method works as well to our Koolatron cooler (which also uses Peltier technology) I realized that short periods of usage do not work because the unit requires some time before it becomes effective. When we go on summer trips we pre-cool the cooler in the house for it to work well during the trips.

2. Then I took the dehumidifier to the basement, where we have a standard 50 Pint dehumidifier which fills its entire bucket in several days. I turned off the large dehumidifier, and left Gurin Dehumidifier there for 24 hours. After 24 hours the reservoir of the unit had 1 oz of water. I am attaching a photo of how much water it collected. After 24 hour of use the big electric plug of the unit got rather warm to touch, so I suspect it uses a significant amount of electricity.

Gurin dehumidifier is quiet and light because it uses thermoelectric method called Peltier. This method is most commonly used in cooling. In 1834 Jean Peltier noticed that when electrical current is applied to the junction of two different metals the heat is removed from one of the metals and transferred to the other. This is the main principal of thermoelectric cooling (and known as Peltier effect). The dehumidifier has cooling unit which is constructed from tiny metal cubes made from different metals. As electricity passes through the junctions between the cubes the heat is transferred and a fan vents the heat outside, a small amount of moisture is removed from the air in this process and condensed and this is the water we see in the reservoir of the unit.

So for this unit to work, it has to be turn on continuously, and it removes a fairly small amount of moisture from the air. It is very quiet, and if you need to remove only a small amount of humidity it will do an ok job.

I was provided this unit for a review and honest evaluation.
