I have it for two months with 149€, I am in a 70 sqm apartment, but I placed it between the rooms and the kitchen. The truth is that it did a very good job, before I had water dripping from the windows, but now not anymore. It went down from 78% to 50% in about an hour. As for the noise, the truth is that it is a bit like having a fan or a small old refrigerator running. But overall, it's fine so far.
I'm still trying to understand how the ionizer works independently of the dehumidifier, as the description says. I don't see that being the case..

Before we put it in a small space, the ceiling literally dripped, it took a few days but it did its job. As for the small water bucket, it makes sense because it is small, there are larger ones if you don't want to change the water often. It saved us
It does its job well as a dehumidifier. As for the ionizer, well, it doesn't compare to pure natural air. I don't feel the air refreshing or anything like that even with the ionizer activated. As for the "drying clothes" function, it also doesn't compare to hanging them outside and letting the sun dry them while being aired with clean air. But for those who don't have balconies, it does something. The tank, of course, is small and is only for about 24 hours. Cleaning the dust filter is a bit of a difficult process because it doesn't come out or go in easily. Be very careful not to damage the humidity indicator because the filter has to go behind it. Unfortunately, it barely goes in by itself unless you push the filter down a bit with your other hand so that it rolls up and goes back into place.
Of course, this problem might only be with my dehumidifier... but keep it in mind just in case!
Overall, though, it's a good purchase. Of course, there are much better options on the market at the same price as well.
In just 6 hours, it brought the humidity down from 57% to 46%. For a 57 sq.m house, it's super. It quickly changed the entire situation and the air in the house. My eyes stopped stinging, which suddenly appeared recently, and in just a few hours, please. I got it today, 10/19/2024. I will return soon with updates.
It doesn't make much noise, you sit comfortably in the room where it operates. Its size is convenient, it can be easily placed in corners and spots of the house so it doesn't disturb. It blows air from the sides and pulls moisture from the front, so you can place it with its back against the wall. The water tank is small but personally, it doesn't bother me. It is quite heavy but it moves easily with the wheels. It has handles so you can lift it. The hose for the external drainage is quite sensitive so it requires care not to be cut. So far, I like it a lot, time will tell.
Generally, the photos do not do it justice. The noise does not bother me at all even in the room, but that is also a bit of a personal matter. It lowered the humidity relatively quickly, but it will show in a week how it goes. The sensor bothers me a bit because it reads 10% less than another dehumidifier and from a thermometer I have.
very good, dries clothes immediately and collects moisture in a few days the house has a different atmosphere. whatever I have bought from Rohnson is unmatched,
After two years of fairly intensive use, the conclusion is that the humidity indicator is 20 units lower than the actual. It doesn't do any significant work, it is not a quality machine and its price is quite high. Look for something else

Is it relatively economical in electricity consumption?
I would recommend it as long as the use is outside the sleeping area.. and that's because especially when it's on the second setting, the fan makes an annoying noise, I give 4 stars for its effectiveness (it really collects moisture easily) & the quality of construction, from its plastics, screen, wheels, if it didn't make this noise I would give it 5. As for the consumption, 172 measured, purchased for €135 two months ago, so yes, value for money.
I am coming back after a few months.. I hadn't used it for a while and I searched to clean the filter and what did I discover..?? That it didn't have a filter, just a mesh that held a lot of dust but it wasn't a filter!!!! Looking for the prices of the filters I understood why (I suspect) it was removed, I exclude that the company doesn't have it in the new product!!! I will check from whom I bought it and will come back to update!!!
Honest choice. I have had it for about two months.
In a room of around 20 square meters, it does the job in a short amount of time, comfortably reaching around 50% humidity.
The second use in a corner of a unified space of about 60 square meters, where it doesn't have the same performance, but still reduces humidity by about 10% in a short time. From there on, as long as you leave it working, it continues to fill up with water.
I should mention that I don't have a point of comparison with another dehumidifier, which is why I find the noise to be a negative aspect (it does sound like an old refrigerator working, unless mine was damaged during transportation), but perhaps one gets used to it over time.
The construction seems to be of good quality, it looks nice, the tank is okay (2 liters, it also has a tube for continuous flow), its functions are simple and understandable for someone who wants a simple dehumidifier for a ceiling price of 150 euros without Wi-Fi and many fancy features. I don't have an opinion on its consumption beyond what it declares.
It was purchased for 142 euros plus 10 euros for shipping. Now I see the price as even better.
Overall, aside from the noise, it's great.
Simple, economical and quiet.It greatly improved the atmosphere of an old apartment (40 m2).
It does not have an active carbon air filter only a simple washable dust filter !
It is relatively quiet. It does not bother at all. It removes moisture in a relatively good time. The negative aspect for some may be the small water tank. For me, who spends many hours at home, it is not a problem. It also has the hose for drainage which helps. It is small in size and elegant. It is a very good purchase for anyone who does not want to spend more money on a very famous dehumidifier. I recommend it!!! Purchase price 135€
Of course, I saw the countless positive reviews and it seems like I made the right choice. I bought it on Black Friday for 132€. The truth is, I haven't found any comparisons because it's my first time buying a dehumidifier and it hasn't been many days yet, but on the first day that I slept with the dehumidifier on, I slept better and didn't wake up with a stuffy nose! I don't know if it consumes a lot of electricity yet. That's it! I recommend it!
It's worth every euro, the whole atmosphere of the house has changed. Clothes dry in a few hours during winter when I have it running with the laundry inside the house

Very effective, quiet compared to other models, simple and economical.
Because it collects a lot of moisture, the tank fills up quickly, but overall, it is an excellent purchase.
It was in a basement that flooded with 40 cm of mud. Two days later, I took it out, washed it with a hose, and the next day it was working perfectly!! What can I say about its build quality then!!!
Positives:
1. It does a good job of dehumidifying. Very good. This is evident not only in the water it produces but also in the atmosphere's feel.
2. The ionizer and filter actually work well, and this was noticeable in the deodorization of the space it achieved.
3. In cases where there are many people gathered in the room and the windows are closed, it prevents the creation of a heavy atmosphere from breath, etc. Also, due to conversations, its sound is not bothersome.
4. The 2 liters of the tank is not exactly a reservoir, but it is enough so that you don't always have to worry about it getting full.
5. As soon as I received it, I opened it and saw that it was ready to operate. I didn't need to add the wheels or anything else; I just plugged it in and it worked.
6. The menu is understandable, but someone should read the instructions to be able to utilize it properly.
7. Its noise is not very bothersome. Especially if there are other sound sources in the room, it is hardly noticeable. It has the volume that, for example, a fan would have.
8. It is economical both in purchase price and in consumption.
9. Its filter is very easy to clean.
10. It has a decent appearance.
11. It has instructions in Greek that are understandable.
12. It has drainage.
13. It has a timer.
14. It is from Rohnson, which may not be one of the most quality brands, but everything I have purchased from them over time has been honest.
-----
Negatives:
1. In very large spaces, it is not easy to respond and takes time to achieve the desired result.
2. Its sound, especially if there are no other sound sources around to cover it, becomes bothersome after a while, mainly because it has a high pitch. For example, one cannot sleep with this dehumidifier in the same room.
3. It is not a device that will impress with its design.
4. The water level is not easily visible from a distance. You have to get close, sometimes even use your phone's flashlight to see how much water it has collected.
5. It does not have any super filter like those seen in more expensive dehumidifiers.
6. It does not have wifi.
-----
In conclusion: Since I just wanted a dehumidifier with a filter and ionizer, it satisfied me 100%. This one does not belong to the category of those that do not dehumidify well, and you regret your money. Quite the opposite. It produces water and corrects humidity very effectively. I placed it in a room that had not only humidity but also a strong musty smell, and within a few hours, that feeling had dropped significantly.
Its negatives do not bother me because I neither sleep with the dehumidifier next to me nor have a huge hall. I saw the dehumidification with the liters of water it produced (and they did not run out). Also, I never use wifi on such devices. So it was exactly what I wanted. Therefore, to those who want to be saved from humidity but do not want to spend a lot of money, I would recommend it.
P.S. I wrote this on 24/09/2023. Today, 27/01/2025, I do not need to change anything. On the contrary, I have to add that the dehumidifier has been working almost continuously for a year and a half without showing any problems. Every day I empty the tank, and every day it fills up again. Obviously, it was a good purchase.
I am satisfied with its performance. It functions perfectly. It reduces the humidity in a space of about 50 square meters relatively quickly. In a smaller room of 20 square meters, it stops and goes into standby mode regularly. It is not silent, but it does not bother me. The humidity indicator is not accurate, but I don't think it matters much. You can also see the measurements with other better hygrometers. I would recommend this machine, it is worth its money!
