The comfi air dehumidifier does what it should do and also quite well, namely reduce the humidity in a 30sqm room. The setup and operation is quite simple and quick. What is not so clear is the setting of the operating modes. There are drying (for laundry), smart (for fully automated dehumidification), continuous (for continuous dehumidification) and the usual operation after humidity. It took something until I understood that the “normal” operation prevails when none of the “extra” options are selected. It can be set better by using the app, but it is not immediately understandable. Another point that led to a star draw is that the air humidity display of the comfi device does not indicate correctly and thus stops too early or starts too late. In addition to the comfi device display, I have set up a separate humidity meter that displays a higher humidity than the comfi device. I confirmed the measurement with two other separate measurements. A second comfi device has the same deviations. Therefore, the comfi device must be set far lower than it indicates and even 10% lower.
The monitoring of the comfi device by app and setting a schedule is positive when and how long the dehumidification should take place.
Trotz of the two negative points I can recommend the product.

I have the device now in operation for a few days and "healed" my 3 liters of water every day in an approximately 100 m^3 space where I sleep and work. When emptying, you have to be careful, the container is quite full. High switch-on current (light flickers short). I don't need the app. I don't know why I should register at any server if I want to dehumidify my air. From 20 pages, 9 pages are missing from safety warnings, which is something exaggerated to me.
With my low-cost sound meter (IEC651 compliant, +/- 1.5dB accuracy) I measure at the smallest fan level in 1m design 44dB, according to data sheet it should be 41dB (but at what distance? I am not an audio engineer, but m.W. sound pressure levels are measured in this - 1m distance, correct ? ). I find the noise is not unpleasant, and although the device turns on and off regularly, I sleep well at 2m distance.

This dehumidifier is excellent! The setup went super fast and uncomplicated, and the app connection works perfectly. I can easily control the device from anywhere, which makes everyday life much easier. The dehumidification performance is strong according to my perception – after a short time you notice a significant difference in humidity. With my humidity of 60-70% in the basement, I don't need a whole night and the 3 litres of collecting tanks are already full. Clear purchase recommendation. I'd buy it again at any time.

Works perfectly.
On average fan level and 55% target humidity and 12h runtime a day, it pulls out 3 liters per day. Madness.
No more moisture problems.
But also draws about 3kWh per day. It's buzzing, and it's getting really clean on the electricity bill.
Over night in the bedroom too loud but let it run during the day.
The good with the practical app control is that it does not have to run practically at night when it has automatically revolved during the day.
Standby consumption despite Wlan app connection and control only 1 Watt.

P.S. The evaluation that describes that the fan continues when the dehumidifier has reached its target moisture does not agree (more). Vvl. Umnein Software Update has been fixed in the meantime?

No more mold on the window, tumble dryer wonderful, have drained the water with the garden hose through the window frame which fits perfectly from the diameter.

The dehumidifier does what he wants. Control via app also works perfectly. Creating schedule, setting the operating mode and the most important for me, reporting when the water tank is full also works wonderful.
Integration in HomeAssistant has worked perfectly.
Definitely recommend this dehumidifier.

I bought the dehumidifier for my grow room to keep the humidity in late blossom controlled between 40-50% and thus avoid mold.

The device fully fulfills its service within one hour, the RLF is lowered from 60 to 40%. The water container must be emptied regularly, but this is not a problem and can also be avoided with an ablasting tube.

In addition, the dehumidifier can be started from anywhere with the app and timetables for switching on and off are configurable.

I tried three devices (Monhouse, Midea Cube and the Comfee).

At the Monhouse with 12 liter dehumidifier power, the noise development was the least, unfortunately also the power. He was too weak to dry or medium-sized rooms. Optically he was very beautiful and had a high quality effect. Smart function was not present. Suitable for small rooms and noise development also for the bedroom. Measured power consumption was about 140 W.

The Midea Cube scored with its 12 liter bucket and a good dehumidifier performance. Unfortunately, he was very loud. The user manual was a catastrophe because of poor translation. But the good midea video could explain all the features comprehensible. I found him pretty old. It can be operated comfortably via mobile phone, Google Home and Alexa via the smart function.
But if you don't care about optics and volume, the device will be very satisfied. Measured power consumption was about 240 W.

My test winner was the contest. It combines the good points of the two previously mentioned devices. Strong dehumidifier performance, comfortable to use via phone (including Google Home and Alexa), visually beautiful to look, high-quality graceful, on small fan level also suitable for the bedroom, with an understandable guide. The 3 liter container is large enough to not normally have to empty it daily. And a real bargain for 189,03 euros.
My apartment is 91 square meters tall and when it is in the bedroom and runs, sinks in the entire apartment slowly, but steadily the lightness (which also created the Midea Cube). Machine laundry was drying after 6 hours, while the device stood next to the laundry. Measured power consumption is just over 200 W at maximum power, making it much more economical than my condensation dryer. On top you get three more than two years warranty.

I can recommend the device without restriction.

Use in the basement. After switching on, the humidity decreases relatively rapidly. Makes very little noise and the app control is great.

We use the dehumidifier wherever we can only ventilate badly (in summer mainly in our cellars, in winter mainly in our sleeping rooms).

The device has a dehumidification capacity of about 20 litres per day and turns off as soon as the water tank is full. This is the case after 12 h when used in sleeping rooms (on the day) or in the laundry room. Since use, we have significantly fewer problems with mold formation and muffy smells, which is very impressed to us.

We find the app control (“Midea”) that allows us to monitor and control the device in real time, as well as the Alexa integration. In this way, for example, the current humidity can be indicated. The displayed values usually differ somewhat from the measured values of our Netatmo station, which does not disturb us any further. The device has different operating modes and setting options, but the meaning and purpose of which has not yet really developed. The operating instructions could be somewhat better designed after the device “plug and play” is usable, but we do not really miss a better guide.

Thanks to the flexible wheels, the dehumidifier can easily be moved from room to room. The full container can be easily removed and worn. The intelligent mode that automatically regulates humidity also works perfectly.

Friends of us used the device for dehumidification at times in the basement after a water break. For this purpose, the apparatus has a continuous function in which the condensed water can be conveyed via a tube into a larger container. Practical!

Overall, the performance of the Comfee is significantly better than that of our older Honeywell device. Both devices move from energy consumption at about 220W. Due to the better dehumidification performance, the Comfee device moves in a frame that is completely acceptable to us.

Clear recommendation for those seeking an efficient and comfortable solution for dehumidification!
