For an 80m coverage area it says. I have it for 4 days in a 35m space and it can't increase the humidity above 35%. Value for money in no case. Otherwise, it is quiet and with very good build quality. I would not recommend buying it at this price.

So far I am very satisfied. I placed it in my living room (about 60 square meters including the hallway) because during the winter, due to underfloor heating, I felt dryness in my space and measured relative humidity with a hygrometer ranging from 30 to 34%.

It takes relatively little time (about 2 hours) in operation to reach 55-60%.

Very accurate and the device's sensor that measures the relative humidity of the room. It shows the same value as the hygrometer I use in the room.

It has the ability for warm humidification, but personally I do not use this function, and the ability to adjust the desired relative humidity in the room. I have set it to 60%. As soon as it reaches that level, it automatically stops and starts again when it falls below 60%.

Conclusion: Very good value for money!
