The humidifier is pretty cool, but I find its design quite primitive (especially considering the price). Of course, I will add right away that I can recommend it, because in the price of up to 10 thousand I somehow did not find anything better with similar evaporating power (other "toys" that evaporate in real 1 liter per day does not even make sense to comment) I have just started the second season of humidification and during that time I have collected a few experiences:
Noise - it is quite noisy for maximum mode - I had it in the living room, but the noise bothered me a lot. On lower power it is better, but this in turn of course decreases the volume of evaporated water. He ended up in the corridor, where the noise doesn't bother anyone - the humid air finds its way into the living rooms, no problem: ) The reservoir says 6l, but in reality if it is completely empty, it will only hold about 5 litres of water after the MAX mark - the volume of the reservoir is taken away by the submerged filters + the total volume is probably given, not the volume after the MAX mark.
At about 23°C and 45% humidity, it evaporates about 6 litres of water per day with new filters (which is not that staggering, but it's not too little either). Due to the principle of natural evaporation, it evaporates the most when the air is warm and dry. About the filters - they get clogged with minerals in the water (Brno water) quite quickly - on the upper third (where evaporation takes place) after a week of operation, a crust of minerals (+ dust from the air) appears and the evaporation performance decreases. For this, I have found it useful to turn the filter after about 2 weeks (dip the crust into the water) and ideally leave it for an hour (to dissolve the crust) and then pour out the water, rinse the filters carefully under the shower and use again. I have been trying to put softened water in the humidifier (same principle as the water softener in the dishwasher) - this makes the resulting crust much more water soluble than the classic calcium scale, but the total volume of minerals does not change and is still very high in our water and clogs the filters. In general, I would recommend doing a quick maintenance every week (and not just "ignorantly" adding water all winter) - pour out the water (where the minerals are concentrated) and turn the filters so that evaporation takes place on a "rested" surface. " When using the aforementioned soft water, the lifetime of the filters is about one winter. When using raw hard water, really count MAX 2months, maybe not even that - then it's up to you when you decide the evaporating power is too low and replace them. I tried cleaning the scale from the filters by immersing them in a descaler (some citric acid, amidosulfuric acid and a little phosphoric acid). It fizzled like crazy and helped extend the life, but I got the impression that the water started to deteriorate faster after that. It's quite possible that the acid washed out some of the antibacterial impregnation from the filters. You can try it and see if that's really what it was. On the design - some humidifiers keep the level for the humidifying mechanism at a constant level (the principle where the tank is bottom up and when the water is running low, some air gets into the tank and the water in the bottom of the bowl is replenished). Here, however, it is only in a primitive way, where the filters evaporating water are submerged in the main reservoir and the level gradually drops. Unfortunately, only about a third of the filter above the surface is used for evaporation and air flow. For this reason, the humidifier evaporates best with a (semi-)full tank, as soon as there is only "at the bottom", the water has to rise through the filter from the bottom and it does not run as efficiently.
The advantage of this design is the easy refilling of water, where there is no need to open the tank and it is simply refilled through a hinged window. This design is also related to the fact that although the humidifier has two large fans, the airflow is not huge. The air path is as follows - it is sucked in from the bottom through a relatively narrow slit, then it has to curl almost horizontally, pass through the filter material, curl vertically again and then into the fan and then out. A little thing I don't like: the cable outlet is on the left side where the filling hole is. That doesn't make much sense to me. Unfortunately, the top of the humidifier can't be put on backwards so that it flips over. In general I can say that it is probably the best humidifier I have seen, but of course it is not maintenance free and count on additional costs in the form of filters
High moisturising performance
Operating costs
The cable outlet is illogically on the side by the funnel

Super experience, convenient water refill, easy to clean, filter catches hard water, doesn't build up a coating on surrounding stuff like ultrasonic, running 24/7 in winter for the second year and all OK.
power
does not pulverize hard water particles that form a coating on surrounding items like ultrasonic humidifiers
large tray
possibility to switch off the LED
automatic monitoring of set humidity

It is quite convenient to refill water through the side funnel, where 6 litres is sufficient capacity. High performance with relatively low power consumption. It doesn't produce steam like ultrasonic machines, so it doesn't attract attention and doesn't mind hard water. In terms of cleaning, maintenance is also easy compared to ultrasound. It just stands there, doesn't spoil the impression in the room, it's pretty quiet, but I run it in my office and not my bedroom, so I don't know how it feels sleeping next to it. You're basically just topping off the water and that's all you care about. In addition, it allows you to add fragrance.
Care must be taken when topping up, otherwise you'll get the scented oil cotton wool pocket wet. Of course, if you buy and change all 4 filters regularly, the operation is more expensive than the ultrasonic version. But there, you're fighting with the water stone again.
