Ventilate and heat, over and over again. I considered buying it for a long time, finally I forced myself to buy it because after 12 years we had a problem with damp in the flat, rusty windows and mould. It has come about since we have been hanging laundry at home, also cooking has increased (family of 2 adults+2 kids). Hence the abnormal humidity. I bought the dehumidifier and I couldn't believe my eyes, the humidity is gone, the dew and mould from the windows are gone too. I added before and after photos. For me, a sentence like: "Ventilate and heat" is just so over the top, and the window experts will tell you that, but absolutely none of them have any idea why it's happening. Who is drowning the Lord God in windows, in this day and age, at today's prices? The only solution is to buy a dehumidifier. We've had the dehumidifier for two days so far, so I haven't tried any other functions. But I'm sure everything will work. Otherwise, the container is for 2 liters, for me sufficient. I've added a photo of them pointing a thermometer at the jar. I switched on the dehumidifier at about 9 pm and in the morning see photos. I removed the container and poured it out. The container is easy to handle. As for the sound of the dehumidifier, people compare the device to an old refrigerator, it is not. Imagine you're in a hotel and the air conditioning is running, that's exactly the sound it makes. So it's okay. I hope I've written everything.

humming, it's not unpleasant, but at night it's better to close the door to the room where you have the dehumidifier on

The sound of the compressor is just like an old refrigerator, a loud metallic knocking that is really audible. However, it absorbs moisture well, it really shows, I play it when we are not at home, or 2 rooms away from where I am at the moment. I didn't notice the effect of the ionizer. the purifier as I said above as if it wasn't.
effectively absorbs moisture
relatively small
low electricity costs on paper
the sound of the compressor is much more audible than a modern refrigerator.
after each loss of voltage the desired humidity is set to a,,, preset,, value that sucks when you move it between rooms
it has nothing to do with the air purifier. the filter which has a 0,5x0,5cm grid doesn't really catch anything

I bought the dehumidifier through a room that is below street level (about a meter and a half below the ground) and we are plagued by humidity and have found mould in places. We have tried various options to get rid of it and the main aspect was the humidity. This machine, in terms of price/performance, absolutely great. I've only had the device for a day but in the evening before going to bed I switched it on and in the morning it was full, it turned itself off, a non-violent indication of a full cup visibly on the display. Overall, with ionization, in such a short time in a 5x5m room, it extremely cleaned the air (plus there was washed laundry hanging out, the humidity rose but within an hour it went down to the "standard" that was there until now, it ran in normal mode with the fan at max, it's really quiet, only I personally fall asleep in front of the TV, so some people may mind the compressor running). I am curious what it will do in about 2-3 days of operation so far I am maximally satisfied!

I bought the product for the living room, because of the dew in the windows, when I turned it on it showed the humidity in the room 63, after 24 hours of continuous operation the humidity in the room 61, so it can't even dehumidify a 3*4m room.
does not hum
small, compact
the humidity in the room can't cope
they have to go 24 hours a day to see any effect
