I'm quite satisfied. The reservoir is large enough so that you only need to refill once a day at the lowest power. However, it takes washing the tray and the base itself once a week or so to ensure that hygiene is done.
Quiet
From 23% to 50% in a medium-sized room at the lowest output with a smaller fan and the heating set to stage 4 (out of five)
It is quite easy to refill water
Aroma droplets are put directly into the reservoir
Cold steam
There's a fog in the humidified room
Lacks the ability to add a carbon or anti-scaling filter
Cleaning
The diffuser has no ionization

The machine is running well. It has two filling options. You either take the lid off and pour water in ( that's easy ), but it's more for smaller refills. When you want to fill the whole tank with water, it is easier to take the tank out, take it to the water tap and fill it. Unfortunately, the tank itself does not have a stable bottom and needs to be held still or it will tip over. I was going to let the humidifier run overnight, but when it runs out of water, it beeps loudly a few times. I could do without it.
laffing a lot
easy filling from above
the beeping cannot be turned off
larger filling is unnecessarily complex
it is harder to clean

It moisturizes well and on the first level with a full tank of water it lasts all night and half a day, very quiet operation. The water is easily refilled, it just needs to be added, nothing needs to be turned, screwed, etc. But they don' t last too long, one stopped working after two years, the other after a year and a half.
easy filling
simple operation
the water supply lasts a long time
fits almost anywhere
sight glass where you can see the water level in the tank
more difficult to clean the inside, many folds, where it is difficult to reach

you can even sleep with it. is most effective when the room is closed. the gentle lapping of water (like in a cave). a 4.5 litre load evaporates in about a day.
silent
low consumption
design, colour white not snow white
