I had a Sharp unit that finally gave out and when searching Amazon I found this new DeLonghi air conditioner with eco-friendly refrigerant. I have always liked DeLonghi products for their stylish looks and this air conditioner is no execption.
I have a metal roof with vaulted ceilings and when it gets hot the upstairs loft gets about 10* hotter than the rest of the house and since this is where I sleep I need some extra comfort. We turn it on around dinner time and put it in the turbo function that uses both water and air cooling to bring the temperature down and then when we get ready for bed we turn it down to the sleep function which is pretty quite for an air conditioner.
I like the easy to read LCD display and the super cooling with the water tank really helps get the room temperature down quickly. This is a solid unit that weighs about 130 pounds so the casters and built in handles help in moving it around. It has all the bells and whistles with 24 hour timer,... Read more

I admit, I got suckered into buying this unit because of the marketing and slick featureset. What a disappointment.

I am returning it as quickly as possible, and would probably avoid Delonghi products going forward. I was trying to get information on where to buy replacement filters from Delonghi USA (& Canada), the former did not reply to several emails (USA tech support), and the latter - the Canadian support email bounced (no such mailbox). What a joke.

PROS:
Really nice & modern color scheme, graphite and silver.
Pretty blue LCD that displays everything you need to know.
Eco-friendly refrigerant
Side handles (because its very heavy)
3M Biosilver Techsystem

CONS:
VERY Noisy - sounds like an old dishwasher when cooling in Water to Air mode (swishing noise, I am guessing the rotary engine cooling off using the water).
Water refilling to get optimal cooling (to get 13K BTU) is annoying & frequent (Tested on a very hot... Read more

I currently own 2 other portable AC units (1 Sharp, 1 Danby...both waterless) due to the window's I have in the old house my apartment is in and this Delonghi blows the other 2 out of the water...no pun intended. I was skeptical about having to add water to this unit, but the level of performance it produces due to this is well worth it. This is now the only unit I leave on during the day for my pets while I'm at work...as long as I leave the doors to the other rooms open, it will keep my entire apartment cool even during the hottest summer days. My other 2 units couldn't produce the same results in tandem. 100% satisfied with this green machine. Gotta love Italian craftmanship!!! Anyone want to buy one of my old AC's?
