    After more than a year of use, I can say that it is amazing. Initially, I was hesitant to buy a dehumidifier in this price range. However, I wanted it to be relatively quiet so that it wouldn't be disturbing at night, and powerful enough to quickly reduce humidity and effectively dry clothes.

    I can say that it fully meets all my needs. Although the airflow is directed upwards, when placed among the clothes it does the job extremely well. An equally important feature was the Wi-Fi function, which allows remote start and scheduling of its operation, both for day and night.

    The relatively large water tank is also useful, as it does not need to be emptied so often. The dehumidifier has been in almost continuous operation since it was purchased, for about 14 months now.

    It is not suitable for drying clothes. It takes many hours for them to dry, and clothes with elastic bands simply do not dry.

    It is truly silent, it sounds like a fan or the air conditioner.

    It's been a week since I bought it, in a house closed for 1.5 years, recently painted, and I have to say that the dehumidifier is a flagship!! In a 130 m2 house, it brings humidity down to 45% in 1 hour. It's worth every euro. As for noise, you can barely hear it. Of course, the electricity bill will show. 04/06/26 I would like to add after 1 year of use, that it is unacceptable to select 50% humidity and for it to stop it has to go down to 45%. That means it has to work all day until it stops at 45% even though you have set it to 50%. The representative confirmed to me that this is normal. Honestly, whatever.

    It is very quiet, quite effective but not for drying clothes because the airflow is not very strong. The ionizer is very effective at eliminating odors but unfortunately does not work independently, only when the dehumidifier is in operation. The power consumption listed on the device (power 400W+) and the noise level (45db) are higher than what is stated in the description. I expect to see an increase in the electricity bill since its compressor does not seem to stop at all, not even after the humidity is reduced to the desired level!!!! I expected it to be much more effective for 30L but the 25-liter one I have is much more effective. However, its low noise level and the ionizer are a luxury! If you have the financial means, get it!! The initial connection to wifi was indeed tricky but the app is a great convenience for controlling the functions.
