Very dissatisfied with this sink, it works constantly anyhow. Recently I began to show air humidity at the level of 30% and that's it, and in this, in different rooms, the value is the same. The air does not essentially moisturize at all, at least this is not felt at all in the room.
I also don’t like the noise level during the operation of the air cleaner, even at the minimum speed I can clearly hear it. So for the bedroom, this unit is definitely not an option. Chinese production, respectively, it will be quite difficult to understand the instructions, nothing is clear at all.
And there is an unpleasant smell during the inclusion of ionization, from which the head begins to crack. So I do not advise you to purchase this model of air purifier, I think for the money you can find a more worthy option that will perform its job better.
