Reliable and very useful.
Definitely an improvement from the older DD3. I still have the old DD3, still works fine but this new one is on a different league. The air coming from the top vent is noticeably hot, you will save on heating. It pteaty silent, and while in use it does not bother me while listening to music, it is lost in the background. The dehumidifing power is unbelievable, I drains the air at an impressive speed. The digital humidistat control panel is very usuful as it allows you to monitor and set your preferred humidity level. It powers off when the desired humidity level is reached, really good feature. So far so good. Let's see if it last as long as the old model which has been used every winter for 8 years. Really good reliable products with almost zero maintenance, low running costs and brilliant performance.

Better that a compressor type, don't believe the reviews.
Works great, not expensive to run, set the required humidity and go. Most importantly, works in all temperatures, my 2 previous compressor dehumidifiers struggling to work in winter, just when they are really needed. This one has been the best so far, keeps my room at 55 constantly in an old 1930's house. Operates automatically with no filters to buy, just brush off any dust once every 2 weeks or so, don't wash it as it's coated. Quiet in use. Recommended

Absolutely brilliant - Warms house - Removes water - Saves money on heating!
Very easy to use. Removed 4 litres in 12 hours. This warms my house so much that I have the heating very very low or not on at all, It is so much cheaper than the central heating @ 10p to 15p an hour. I have detached 1900 cottage with solid walls! I am seriously impressed. I have used for 3 days and my walls are noticeably drier to the touch and my bedding doesn't feel damp. a few parts of the wall had bubbled and they are now completely dry. So glad I bought these. I thought it was a tad expensive but is worth every penny.

Soaks up moisture like a sponge, quiet.
Strongly recommended. Updated review after 6 weeks use. Hopefully you can tell from video that the noise issue mentioned below has all but disappeared, it's exceptionally quiet on high or low. Colour; off white with a hint of cream, my wife and I like it. First of all the DD3 MK2 soaks up moisture like a sponge on low or high. We previously had a DD128 for 7 years where it was used several times a week throughout the year, keeping humidity right seems to help my daughters asthma. Although the DD3 is larger the shape makes it blend in. It is especially useful for laundry. We had a couple of issues which were sorted out by Simon at Ecoair. On first use you may find it noisy when on low after it’s warmed up, maybe 10 minutes, low pitch drone or whistling noise. This will reduce after a week or so, I put it down to ‘running in’. At first we thought it was faulty and Ecoair very promptly changed it and said if we weren’t happy they would refund. Excellent. So, for and against. For; soaks up moisture like a sponge, very efficient. Non intrusive noise, especially on high. Excellent after sales service made me trust this company. Noticeably heats the room. If you have solar panels then there's little cost involved in running it. Against; slightly noticeable sound on low (but we’re keeping it!). Some people may notice this. If it’s placed in a hallway etc, I don’t think it would be an issue. As a work around, run it on high rather than auto then it would only go onto low after the humidity level is reached for a short time while the fan cools the inerds. The ‘full up auto cut off' could do with adjusting as it allows a little to much water into the reservoir. You might want to take the complete machine into the kitchen before emptying. Speaking of which, you might want to save the water for your indoor plants, watering and spraying the leaves.

Perfect for the price
Works really well, not too loud, and has a large water tray (double the size of others) that only needs to be checked on and emptied weekly or daily if it's humid (more often if it's particularly humid or is being used in laundry mode). A reviewer comparing it to a commercial dehumidifier, that costs well over double the price of this one, said this unit was flimsy and I have to agree with them. It is flimsy, but it's not bad. In a home setting it's perfectly adequate. If you're going to be ragging the dehumidifier around as part of your trade then I would perhaps suggest a commercial unit built from metal. Another reviewer reported that the dehumidifier was difficult to empty without spilling water everywhere... I haven't had any issues with this personally, even with a full tank, just empty the tray at the corner where the hole is. I must add that the plug should be avoided -- unless you're constantly draining the tank with a hose -- as it doesn't empty all of the water out of the reservoir. Tip: Make sure to dry the plug and hole before plugging them up as the tank will leak when filled (the same applies to washing machine filter plugs). Lastly, another reviewer mentioned error codes. I haven't had this issue, but would suggest contacting Amazon or EcoAir and querying the 2 year guarantee that comes with the dehumidifier's purchase. Note: • Having previous experience of an air filter that I run 24/7 over many years I would recommend pulling the tray out whilst the unit is resting (it will beep). That way the power button won't wear out. • Dessicant is great for Winter as it heats the air; which can get uncomfortably toasty in a humid summer. Compressors are better for Summer as it cools the warm air, but don't work well in a cold environment. Update: After nearly half a year use, where I routinely emptied the tank before it got full, I found that the dehumidifier doesn't automatically shut off when the water storage tank is at max capacity (a safety feature mentioned on the listing). The float doesn't cut the machine off for some reason. Unfortunately I was out at the time (though others were in) and it resulted in the unit overflowing and soaking a carpeted stairwell. This was on the 55 mode, so would urge extra caution to those using it on laundry mode or 40. Amazon stepped in on my behalf. Not sure about the 2 year guarantee, I wasn't given an option.

Excellent, reliable, efficient machine
Excellent product . Collects more water than my other two dehumidifiers and works well in minus degrees temperatures.

Absolutely brilliant
We are in the middle of a refurb on a wide beam barge. We have had water dripping down the walls, everything is damp, even though we mop up constantly, have the heating on and are insulated. We have a few bits to do, but we are even getting ice bobbles on the ceilings, waiting for us to put the last of the ceiling up, but of course we will still have water ingress. After much reading and investigation I opted for this. I wanted a dessicant type, which this is. I couldn't get the make I wanted and so went for this as a 2nd choice. Its been brilliant. We have had it on for 24 hours now, our humidity has gone down from 98% to 71%, we woke up with no water on the walls, the windows were dry and nothing felt damp this morning, even though we had 6" snow last night. We've extracted 6.5Ltrs water as it releases a bit of warmth, our variety also dries laundry, but we are way of trying that bit out. This is excellent value for money and we are thrilled. Would recommend to try, we are shocked at how efficient it is and what a difference it has made.

Effective, appears a quality build... feels like it was worth price paid.
The ecoair met my expectations. It is fairly quiet for something that moves a lot of air (not silent but a lot quieter than fan heaters we have, for example) . It removed a lot of water quickly. I used it to help speed up plaster drying out so that I could decorate before a kitchen installation and it worked a treat. (There are different schools of thought on whether that is a good idea but the highly experienced plasterer I used said it would be fine to use a dehumidifier so I went with it). I bought a none condensing one so that I could also use in an unheated garage in winter to occasionally dry clothes. I saw recommendations for this model when I looked into that application and use to dehumidify a cold garage. I feel quite confident this will work, although not yet tried, as it is within the operating parameters for the unit. There is an option to run water to a drain via a supplied outlet tube, as well as via the removable tank. The tank requires a firm tug to remove for emptying and I could imagine someone with a weak grip or no heft might struggle. Overall very pleased. More than I planned to spend but probably worth it, it looks well made. (I say ‘probably’ only because I will only use occasionally rather than reservations over effectiveness. Also can’t compare to much although I did buy a good, smaller capacity, condenser unit for about £80 less a couple of years ago. That other unit was not suitable for lower temperature usage). The on board humidity sensor gives the same reading as a separate Govee humidity gauge that I have which also gives some confidence.
