UPDATE 5/14/17: I am very sorry to say that after performing incredibly well for several months that my dehumidifier no longer extracts water from the air. Considering I had it running (on "auto) 24/7 since I purchase it in October of 2016, I can't say I'm sorely disappointed... but I AM disappointed. Six months worth of use at a little more than a dollar a day. Still cheaper than fighting mold and wood rot but would I buy it again? I just messaged the company today and we'll see how it's handled. I WILL update this review.
I researched dehumidifiers in depth, for almost a week. This is the one I settled on and was quite excited to find Amazon had them back in stock!
10/15/2016: I've only had this dehumidifier for 24 hours and so far, I love it! I WILL update this review to reflect any changes as my experience with it goes on.
TL;DR: MUCH lighter (as much as 30lbs lighter!) and quite a bit smaller than the top recommended compressor type dehumidifiers. Smart design features such as the "3D Louvre" system, ionizer, eco-mode, laundry drying turbo mode, attractive night light, and continuous run with included drain hose make this a feature packed model at a competitive price. The fan noise, even on turbo mode, is comparable to an oscillating room fan or perhaps an AC unit. There IS a smell to the exhaust air, most likely due to the ionizer feature, but I don't find it bothersome or "chemically" as described by some other reviewers; more like a "clean" smell. The air is warmer and in the approx. 280 sq.ft. of space I bought it for, it may replace a small space heater, particularly when used in it's turbo laundry mode. Dumped the tank twice in 8 hours. That's more than half a dozen of those unpowered hang up desiccant bags did in two weeks. Works like a champ!
I bought this unit specifically to use inside our older 40' bus RV conversion. I live on the coast, in the Pacific North West, and recent storms have made me take notice of just how well (or poorly) weather proofed it is. Spring showers? No problem. An inch of rain in 24 hours blowing sideways at 50 mph? Leaks!
The size and weight of this unit means I can easily place it pretty much anywhere, even on top of the kitchen counter, with out harming the surface. In fact I have moved it once in the last 24 hours, splitting the time pretty evenly between the front and rear of the bus. I plan to route a longer drain tube to allow it to drain onto the ground and then it will spend most of it's time in the front half of the bus, where most of the moisture problems are.
So far, in the first 8 hours, I had to dump the tank TWICE. The 4.2 pint tank wasn't completely full either time so I'm going to guesstimate it drew six pints out of the air in my bus in the first 8 hours. The humidity monitor I installed at the same time said it was 89% RH and 64 degrees F, when I first started. Eight hours later it was showing 71% RH and 63 degrees F (yes, the exhaust air is warm, but it is not a space heater). I had been using those hang up desiccant bags (popular with RVers), three at a time, and they couldn't draw even a fraction of this much water, even given a week. Assuming this unit continues to work as expected, it should pay for itself from the savings in not buying any more of those bags in it's first year of operation, and it is FAR more effective too.
The only thing I could possibly tick as a negative is that the included drain hose *that I received* seems to be some sort of metric size. I went looking for a much longer hose, taking a small sample of the OEM one with me, and we discovered that it is not a true 7/16" inner diameter but rather a bit larger, making a tight fit difficult. I recommend using the included hose to attach to the unit and then, if you need more hose, purchase a splice and use a small hose clamp to make the extension possible. A longer, direct replacement, may be difficult to source, especially in North America.
DD122EA "Classic" vs "Simple"? With a price difference of approx. US$50, this is a choice I mulled over myself for quite some time. If Amazon had not restocked the Classic just before I made my purchase, I would probably be reviewing the "Simple" version instead. What does the extra $50 get you? Ionizer and the motorized "3D Louvre" system, both very attractive features, especially after having used them first hand. I also prefer the push button controls of the "Classic" model with their independent indicator lights but perhaps the simpler rotary control of the "Simple" one might be easier and more intuitive? All in all I am quite pleased I held out for the Classic version and if everything keeps working as it should, I will have felt that $50 price difference is money well spent.

Desiccant Dehumidifier Comparison Chart
How much does it cost?
It costs 330 Watts/hour to run on Economy mode but only 30 Watts/ hour when in sampling mode.
Compressor dehumidifiers are quoted at a standard 80% RH 86°F, this means a 31-pint compressor type will extract a maximum of 31-pint only when the temperature hits 86°F. Any lower than this, see the orange line on the graphs to see how the DD122 Classic outperforms it.
- Do you know that DD122 Classic will extract 15-pint per day regardless as long as the temperature is within 34°F - 104°F.
Desiccant V Compressor Performance Graph
Compare the DD122 Classic to a 31-Pint compressor dehumidifier:
These 2 graphs plot the performances of the DD122 Classic against a typical 31-pint compressor dehumidifier under two humidity conditions of 60% RH & 80% RH.
This is because compressor dehumidifiers extraction rate are measured at 80% RH 86°F (a standard measure) but we measure our desiccant dehumidifiers at 60% RH 68°F.
Lets compare both under each of the two different humidity conditions:
- At 60% RH 80°F, the DD122 Classic matches the performance of a 31-pint compressor dehumidifier.
- At 60% RH at temperatures below 80°F, the DD122 Classic exceeds the performance of a 31-pint compressor dehumidifier.
- At 60% RH 86°F, a 31-pint compressor dehumidifier only extracts 17-pint.

Electronic control panelPortability is an important consideration when purchasing a dehumidifier. You may want to move the dehumidifier from room to room. Whilst the the DD122 EA lightweight at 13.2 pounds, it is equipped with a collapsible carry handle to make portability more manageable. |
Water tankThe DD122 EA Classic has a 4.2 pints (2 Litre) tank capacity, positioned at the side of the dehumidifier like a drawer. There is no need to move the dehumidifier when removing the tank to empty. There is a lid covering the tank to avoid spillage and a carry handle for ease of carrying. |
Continuous hose (optional)You can use the hose provided (one meter length of 7/16 inch diameter) to drain the water directly to a drain or sink to save emptying the tank regularly. You need to remove the knockout at the back of the dehumidifier and pass the hose through and attach to the connector. |
Anti tilt protectionSafety is regarded as a top priority when selecting your dehumidifier. The DD122 EA Classic is equipped with a Tilt over safety protection where it powers off automatically when the unit tilts over to safeguard you and avoid hazard. |

LonizerIn the air there are positive and negative ions that affect our breathing. Positive ions cling to the water particles in the air making breathing more difficult. In humid air negative ions helps to relieve breathing. The more water particles in the air, the less oxygen particles are able to fill the air so ionizer coupled with dehumidification, restores the negative ions that makes the air clearer for us all. |
3D LouvreThe DD122 Classic comes with a 3D Louvre as a standard. It helps to direct air more effectively depending on your needs. It can channel airflow over a Wide area or pinpoint to a Spot area and improves the efficiency of your dehumidifier. Use Wide channel to dry a room on an even air distribution and use the Spot channel to pinpoint problem areas and for laundry drying. |
Auto Restart FunctionDD122 EA Classic is able to automatically restart for example, after a power failure. Once the power is restored, the DD122 Classic will continue to operate at the previously selected settings. Very useful if used to dry your boat, RV or unoccupied properties in the days before using them. |
FilterFilter is easy to remove, sliding in and out easily for quick regular cleaning. The filter traps dust and needs to be cleaned regularly (every 2 weeks) to keep the dehumidifier dust free. Clean by gently brushing or use a vacuum cleaner. |

Doing Well in Outdoor Shed Despite Freezing Temps
Bought this little unit after reading about desiccant dehumidifiers and how they don't freeze up like regular units. We use it an equipment shed to keep moisture and dreaded camel crickets away. With 5 months of use and at least 20 days below freezing, it is running fine.
