EcoAir DD3 Simple Desiccant Dehumidifier

We have had the dehumidifier only 5 days so too early to comment on reliability, but with a 2 year warranty we aren't concerned.It was purchased to replace an ancient ebac and so far has worked incredibly well, extracting far more water than the old one had. The unit is well designed with clean, uncluttered lines and simple controls. It is quieter than the compressor models but I wouldn't want to sleep with one running in the bedroom as it does produce fan noise. In the first 36 hours it extracted 9 litres of water from two rooms. Part of our house has solid stone walls and is subject to condensation especially during the winter months and the windows are dry. Although it doesn't come with castors the machine is very lightweight and is easily moved around the house as needed making it a very convenient addition to keeping the home warm and dry.My only regret is that I didn't spend a bit more and get the model with the bacterial filter and ioniser. That's not to say that we aren't very satisfied with our purchase.We have previously bought several Ebac models - with varying levels of reliability and efficiency, but so far we are very impressed with the efficiency of desiccant dehumidifiers.Update: 14.08.2018The dehumidifier is still going strong. We bought another one 2 years ago to use for drying laundry primarily - our house is kind of spread out and it was too big a job for one machine - and the new one is still going strong too. The one we bought in 2014 is in use every day for around 6-12 hours, depending on the time of year, and we never have condensation on our windows in even the coldest weather, and no black mould on window frames or around window openings - where solid walls have contact with the outer cold air and inner warm air.Very impressed with the machines to the extent that I am buying another one for my son to use in flat to dry laundry etc. Not the cheapest but very effective and, so far, reliable

This is in my opinion the only low(ish) cost domestic dehumidifier that works efficiently and reliably in UK's climate and in unheated areas. I use it for an unheated annex and actually bought another one for double garage area.Minor gripe, on an initial run from new, there is a very faint smell of plastic/styrene, but it does go away after dehumidifier has been used for 7-10 days.I actually did a "beauty contest" with another EcoAir compressor dehumidifier rated at 20l/day that I considered to be quite efficient until I bought DD322FW.At 14-16 deg C and 50%-60% RH, the DD322FW (dessicant type, rated 10l/day) extracted 2.5 times more water than the compressor one rated 20l/day did, both using the same power!.I prefer the Simple controls (mechanical humidistat) as you can put dehumidifier on timer and run it only at night in summer, when it is cooler and humidity is more of a problem. I run it all day now that the fog is upon us :) in autumn-winter-spring . Also, electronic controls failed after 2-3 years on my previous two dessicant dehumidifiers (earlier models similar to DD122FW).Also, DD322FW dehumidifier has a simple washable filter which again is good for long term maintenance (no extra costs)For in-house (heated) use, or for humidity control above 80%RH, compressor dehumidifier might be as good as DD322FW in the UK, but in my opinion right now nothing beats dessicant dehumidifiers when it comes to keeping unheated areas dry and garage rust prevention (RH below 60%). And of course there is no ice build-up at low temps with dessicant type dehumidifiers.The only real drawback is that the price is quite steep for a dessicant dehumidifier, 3-4 years ago they used to be 20%-30% less expensive. But it is worth it, in fact if you use it a lot below 15deg C it will pay the price difference to a compressor dehumidifier of the same power within 2-3 months in reduced electricity bills.

My garage, which I use as a workshop, is detached so gets no residual heat from the house, and two walls are partially below soil level so it is inherently subject to damp. I have installed this dehumidifier in it together with a small convector heater to stop the humidity rising to dew point level and so protect my tools and machines. This dehumidifier is very suitable for the purpose because (1) it will work at temperatures down to 1 deg C, (2) it has a variable humidistat which can be set to a higher level than would be acceptable in a house but which will still prevent dew formation, (3) it can be turned on and off from the mains without damage, so it can run off a smart switch set to keep it active from dusk to dawn when the risk of high humidity is greatest, and (4) when it has reached its target humidity it powers down into sleep mode with the fan off and consuming practically no electricity, and continues like that until the humidity rises again and it it switches itself back on. I can see from the readings on the smart switches (TP-Link HS110, HS110 bought at a reasonable price on Black Friday) that this approach is going to add quite a bit to my electicity bill, but short of rebuilding the garage with better insulation and draught proofing it is the best I can do.Returning to the point of this review, the EcoAir DD322 Simple is I believe the best dehumidifier for this job, and indeed most others I can think of that requires a dehumidifier.

I am happy with the performance of the device, it works very well in my setup (around 50 sqaure meters)It absorbs a lot of water and we no longer have an issue with the mould and it is great at drying our clothes.However I remove one star for the fact that it generates some weird smell when in operation , I think in time the smell fades ,but I have the device for a few months now and I can still feel the smell (it is not as strong as it was in the beginning).Considering the size it does not make to much noise when using it at normal fan speed ,but if you are like me you will not be able to sleep near it.I hope you found my description of the device usefull.
