Bests & Worsts Reviews from Amazon

I have purchased two of these Eva-Dry EDV-2200 solid state Peltier dehumidifiers over a period of 14 months, and now, about 17 months after having purchased the first one, I can state that I am very satisfied with the performance of each of them; I also own one of the EDV-2200's smaller cousins, the EVA-Dry EDV-1100 (now in its 17 month of full-time service), and am satisfied with its performance as well. Incidentally, I own several small wall-mounted digital humidity meters, aka hygrometers, and these devices, when one of them is mounted in a room or space treated by one of the Eva-Dry EDV-2200 dehumidifiers, graphically demonstrate, via the rapidly-dropping humidity percentage reading, how effectively these small Peltier effect dehumidifiers work! Certain rooms in our house get damp at many times of the year, and so I decided, about 18 months ago, to purchase a dehumidifier for each of these spaces. When reviewing available dehumidifiers, I quickly came to the conclusion that I did NOT wish to purchase an old-style mecahnical compressor-style dehumidifier, the type that uses a motor and a compressor, and I decided that rather, I wanted to purchase only a Peltier effect dehumidifier, since there are no moving parts in it other than the small 12VDC muffin fan that moves the air. Being an electronics engineer, I was also aware that Peltier effect devices (the active component that removes the moisture from the air), which are solid-state and contain no moving parts, can easily last for anywhere from 10 to 30 years, or longer, trouble-free. When I reviewed the various brands of Peltier effect dehumidifiers that were available, I realized that many of the brands and models consistently earned very poor online reviews, for both performance and reliability, and this led me rather quickly to the realization that the Eva-Dry brand Peltier effect dehumidifiers, both the small EDV-1100 and the mid-sized EDV-2200, were the ones that I wanted. I first purchased one each of the Eva-Dry EDV-1100 and the EDV-2200 models, and then, in less than 12 months time, I purchased a second EDV-2200 model. I use all three of the Eva-Dry Peltier effect dehumidifiers 24 hours per day, 365 days of the year, and two of them, the two oldest ones, have been in full-time sevice for about 17 months now, and I am very satisfied with their performance. I should also mention that after about ten months of full-time service, my oldest Eva-Dry EDV-2200, the one that I purchased about 17 months ago, eventually started to exhibit excessive fan nois, that is, the fan grew louder day by day, and it started making sounds indicating that was it unhappy and that its bearings were failing. Sure enough, the fan ultimately failed (it seized up and froze) within a span of a few more days, and I quickly noticed this fact and promptly unplugged the small black switching power supply so that it would not overheat from the excessive current draw due to the frozen fan. I then dragged the now-not-working device into my workshop, opened it, removed the dead 92 mm 12 volt DC cooling fan (which, luckily, is a commonplace standard-size cooling fan used in many types of computers and other pieces of electronic equipment) and replaced it with an inexpensive standard 92 mm 12 VDC cooling fan (one that drew between 0.15 and 0.3 amps, and that had an airflow between 32 and 60 cfm) that I purchased for about $8 from an electronics supplier on Amazon. I then returned the unit to service, and it has been functioning perfectly since this repair. Incidentally, I will also mention that the switching power supply which came with the first EDV-2200 always ran a bit hot -- that dehumidifier was labeled as drawing 6 amps at 12 VDC, and in practice, it seemd to draw a bit more than that (current drain measurements were made with both a digital multimeter on the 10A DC range and with a clamp-on DC ammeter) and the black power supply (aka power adapter) always ran quite hot. The newer EDV-2200 which I purchased in Oct. of 2012, while it appeared identical to the older EDV-2200 in terms of outward appearance, bore a label on the rear of the unit which stated that it drew only 5 amps, which is one amp less than the older version of the EDV-2200 that I had purchased 13 months earlier, and, sure enough, the power supply (labeled as supplying 5A at 12VDC) on this newer version of the EDV-2200 seems to run somwehat cooler than the 6 amp 12VDC power supply that came with the older version of the EDV-2200. In closing, I want to share with you a very important caveat that it appears that a lot of purchasers of these devices have willfully and blatantly ignored. I have seen complaints in online reviews from some customers who had purchased the EDV-2200 (or its smaller sibling, the EDV-1100) to the effect that these dehumidifiers did not pull sufficient moisture out of the air in the room in which the dehumidifier had been installed. A subsequent close and careful reading of many of these somewhat-negative reviews showed me that the vast majority of the people who were complaining about the "slow" rate at which the Eva-Dry EDV-1100 and EDV-2200 Peltier effect dehumidifiers were removing humidity from the air were people who were valiantly, but often vainly (no surprise there!) attempting to use the devices in rooms that were sized far larger than the manufacturer's stated effective treatment area for the Eva-Dry device that they had purchased. Therefore, I want to remind prospective purchasers of these devices that the vendor clearly states in their marketing material that the EDV-1100 is rated to effectively dehumidify a space of up to 1100 cubic feet in volume (that would be, for example, a 10 ft. by 11 ft. room if the room had a 10 foot ceiling height), and that the EDV-2200 is rated to effectively dehumidify a space of up to 2200 cubic feet in volume (that would be, for example, a room measuring about 22 feet by 10 feet, if the room had a 10 foot ceiling height). It seems that a large percentage of purchasers of these devices proceed to install their Eva-Dry dehumidifiers in rooms that were far larger than the rated air volume in cubic feet, and then some of these same purchasers end up complaining, in their reviews of the device, that the device did not pull enough moisture from the air in the room that they were attempting to treat. It is my studied opinion that if you use these Eva-Dry Peltier effect dehumidfiers in spaces/rooms that are consonant with the manufacturer's declared effective treatment area (that is, 1100 cu. ft. for the EDV-1100 and 2200 cu. ft. for the EDV-2200) they will perform quite satisfactorily.
