Very good machine with a powerful motor, there is not much difference from the 20-liter one, they both take the same HEPA filter because I have both, prefer the one you will find at the best price, their power difference is very small, the noise is not very annoying, it doesn't bother me at all, even in the bedroom, some people who are sensitive to sleep may have an issue, but it is one of the quietest. However, do not look for a dehumidifier with a compressor and expect it to be completely silent, it has a light sound like a refrigerator working but much softer. It does a very good job, the container that holds the moisture is moderate for its category, you can also connect it to drainage if you have a siphon nearby, there is a tube in the package, but compared to some others, for me, it covers me to empty it once a day. I live in an apartment with good insulation, so it does not hold much moisture, if someone is in a house and has a lot of moisture, they will need to empty it more times. It has a system that stops when it fills up to prevent overflow, the only negative I have is that the HEPA filter costs 30 euros, and if you use it 24 hours a day, it lasts about three to four months, but it does a very good job, and the positive thing in this case is that it also keeps the dehumidifier's collectors clean. There is also an additional filter before this on the lid, which, however, keeps the large particles and hairs, you need to clean it at least once a week with a vacuum cleaner and the day after the filter according to the use you make. When the HEPA filter completes the hours, the dehumidifier stops its operation and displays a shape on the screen that is the filter, showing you that you need to replace it to start again, you need to press the clock icon for 5 seconds and start counting again from the beginning, and the dehumidifier starts working again. However, if the HEPA filter gets dirty before the hours it counts, you see it from the indication on the LED in the corner, it turns red and shows it on the indication when you put it without dehumidification, only as a cleaner, it shows a large number. I opened it after years to clean it, unfortunately, it is not true that because it has a filter, it does not get dirty, the internal condenser was very dirty, air and dust pass through cracks that the plastic has on the side and below, see the motor and on the floor, it had a finger of dust and hair, it definitely needs to be cleaned the second year to be able to perform, while you see the condenser outside when you remove the filter, the paper HEPA filter is clean, but here inside it was very dirty. The good thing is that it is quite easy and its plastics come out, first remove the back plate, then the sides, then the front cover, and lastly the screen with the board, the top part so as not to get wet on the board, be careful it has small boards, and on the front cover where the LED light is that shows the air cleanliness, do not let water fall. WARNING WHEN IT COMPLETES THE HOURS ON THE FILTER, THE ICON ON THE SCREEN FLASHES A SQUARE ICON WITH THE FILTER AND THE DEHUMIDIFIER STOPS WORKING TO START AGAIN THE DEHUMIDIFIER, IT IS NOT ENOUGH TO CHANGE ONLY THE FILTER BUT YOU ALSO NEED TO RESET THE DEHUMIDIFIER, THIS IS DONE WITH THE ON-OFF OPEN AND PRESSING THE CLOCK ICON AND IT STARTS COUNTING AGAIN FROM THE BEGINNING OF THE HOURS AND THE DEHUMIDIFIER STARTS WORKING AGAIN
