Product information

The neat De'Longhi DES12 dehumidifier is designed to remove moisture and damp from homes, and can also be used to dry clothes. With its pull-up handle, it’s easy to move around the house too.

It has a 3-litre tank with level indicator, with the Tank Control System automatically stopping extraction when the tank is full. There’s a humidistat for setting the desired level, plus an electronic ant-frost device that works down to 2ºC.

The double condenser elimination system gives the option of discharging the removed moisture directly into the tank, or continuously through a 2m pipe (included). Finally, thanks to the Bio Silver Tech system, the air the DES12 blows back into the room will always be thoroughly filtered.

Q & As


De'Longhi DES12 Compact Dehumidifier 4.3 5 71 71
A slimline useful product. I found this product was all I hoped it would be. It dried the damp patch quite quickly and was not obtrusive.I liked the design and colour. 04 April 2014
good product First one didn't work but collection and re delivery was sorted easily. Very nice and compact so it doesn't get in the way. Lead could do with being longer. Noisy but does a great job. Would have given it a 5 if it wasn't so noisy and had a longer lead. 28 March 2014
After sales hopeless - swapped out for different item I was initially pleased with this but it became very noisy. Sent back for repair/replacement and De Longi messed us around for 6 weeks (including offering a new one, then apparently losing the authorisation for that) then seem to have admitted they've lost the dehumidifier. John Lewis offered full purchase price against a different one so full marks to JL but I'll NEVER buy another De Longhi product. (This was important as trying to dry out bedroom from roof leak, and has affected my heath significantly! This had been communicated to DeL...) 14 March 2014
De'Longhi DES12 Compact Dehumidifier It does what it is meant to do and has been working well. A little too noisy to keep in the bedroom all night, but all motors make some noise, so not a problem. No problems at all so far. 19 February 2014
Struggles in a cool environment After a week it collected only about 1/3 of the water of my previous DeLonghi DNC65 - in conditions that were the same. That dehumidifier, after 5 years of almost constant use, had died. I suspect this reflects on the different non-compressor technology used in the DNC65 and the DES12 may well work better in temperatures above the 19-20 c to which my house is heated. DES12 certainly is cheaper to run than the 65 but since it wasn't doing what I needed it went back and a replacement 65 was bought. 12 February 2014
Noisy I have returned this product as the compressor causes the floors of our house to resonate with a throbbing sound that is audible throughout the 3-storey building. I do not consider this to be acceptable for a domestic product that is intended to be used in living spaces, such a bedrooms or living rooms. De'Longhi should have isolated the compressor from the casing with substantial rubber bushings, which they don't seem to have done. I can't comment on its effectiveness as I returned it promptly. The fan is not too noisy (similar to a fan heater), but be warned about the low-frequency throbbing, especially if you plan on using this on suspended floors. 10 February 2014
Brilliant product bought this for my sons bedroom which is very damp, this has made such a huge difference, no more wet windows in the mornings, bedroom feels much warmer and much less damp. best product I have ever invested in. 06 February 2014
I have dry walls! I had a big problem with wet walls on 2 outside walls, causing black mould and meaning a good wipe down and de-mould spray was needed every week or so. No more! I used it every day to begin with to get the wet out of the "bones" of the walls, from the beginning I was collecting half a tank over a couple of days (I'm in a one bed flat, no living room). I now use it maybe twice a week when the walls feel damp to the touch, and can still see the effects in the tank after this, though the volume has reduced. I'm happy with the size of the product, any larger and it might not hide away if I have guests over, but the size means I can hide it behind a mirror, or squish it in the wardrobe. It's also very easy to move around with the handle on top, and not overly heavy (we clicked and collected and my friend carried it without much trouble - easier than the microwave and small freezer I made him carry before). Glad my friend suggested a delonghi over a cheaper brand, it's been well worth it. 06 February 2014
