Question about Xiaomi Mi Smart Antibacterial

That should be sufficient, but you should also bear in mind that the humidifier is equipped with a fan, which is clearly audible. There is another solution from Xiaomi that works with rotating discs, as known from the Venta air washers. The power consumption would be significantly lower and the noise is also less.

You can also fill it very well from above. Personally, I find the solution with passive evaporation more optimal, as it also prevents the rooms from being overhumidified. It is also suitable for rooms of 40 square metres and works very reliably. The cleaning effort is also there, but it is kept within limits.
