I have the 25lt model. I have had it for three years with continuous operation. Incredible machine, it immediately reduces humidity, quiet, reliable, trouble-free. Highly recommended.

It does an amazing job at absorbing moisture but is definitely not for people who can't stand noise. The 4 stars because for its price, it competes with machines of greater value. If I were to base it on the issue of decibels, I would have given it 1 because there is no zero.

It has been at my disposal for about 20 days in a 90sqm apartment. Simple, quality device, it does exactly and even more than what I bought it for. The usual humidity in the house is about 75% and with this particular dehumidifier it easily drops to the normal levels of about 55%. Sometimes combined with the ionizer, it creates a pleasant - healthy environment in the house and at the same time maintains the normal temperature in the rooms for longer. The water tank fills every 1-1.5 days and the filters are cleaned every 2-3 weeks. Everything is removed very easily, just as easy is its operation and programming from the touch panel on the top. Of course, as with all modern electrical appliances, time will tell us more. :-/

Purchased for a space of about 85 sqm... From the first day and within 5-6 hours, it reduced the humidity from 72% to 55-60%... At first glance, it seems to be doing its main job well and even more than that... It requires a little attention because, like all dehumidifiers with a compressor, if the room temperature is below about 12 degrees, then the device struggles to perform dehumidification... Other than that, it is a quality device, economical, and the noise is not particularly bothersome... Of course... time will tell for the future...

The Kullhaus Qualis 25L has incredible performance. In a 94 sq.m. home, it helps a lot in saving heating oil!! The consumption has dropped significantly!!! It pulls moisture (water) from the surrounding space and the heat from the radiator lasts longer. The energy it consumes is low compared to air conditioning units. The noise is noticeable if it is operating next to you!!

The machine blows normally, but I can't understand those who say it makes noise; even at full power, it's okay, tolerable, and fine

Very mixed feelings. It works fine, but there are unfortunate shortcomings. Power cord is too short, and wheels are fixed on one side. It won't remember settings after losing power, so moving it around is always a little annoying.
Noise level is okay, just be real and don't expect to sleep in the same room.

I come from the Meaco DDL8 dehumidifier with zeolite. Fire in the pockets from consumption.
I got the Kullhaus and I really saw economical dehumidification.
The Meaco burned 660 watts/hour, the Kullhaus 250, one third.
Good construction, lowers humidity to desired levels, in a house of about 80 square meters.
The only downside is that it is noisy.

We have had it for 2 months, it reduces the humidity by 45-50 in an 80 sqm apartment with several walls in between, the bin is quite large, you forget to empty it.
In the clothes drying function, it dries them within 12 hours.
So far, no problems.
As for the noise, it is permanently on the 2nd level, moderate to none. Obviously, you don't put it on the 3rd level to operate at night.
If any problem arises, I will come back.

I don't know if I'm doing something wrong in its use, but being on all night with the air conditioners on, in the morning the windows have moisture. Also, the ionizer doesn't seem to do anything special.

Reading very good reviews about the corresponding 20lt per day, I chose the smaller 12lt/day as my space is not unified and the apartment is 80 sq.m. Indeed, it is quiet and I hope it has low consumption (the bill will show). However, in the unified space, which is no larger than 50 sq.m., while the water tank fills up, it fails to reduce the humidity, which is around 65%, and only lowers it by 2-3% after hours. I also personally found the operation handling difficult and the choice of symbols for each function mismatched. It is quite suitable for the square meters it is designed for. A big advantage is the consumption, the size of the tank, and the fact that it is quite quiet

Excellent dehumidifier, beautiful and particularly high quality (no comparison with the dehumidifiers of department stores), I put it late at night in the hallway between the living room/kitchen and bedrooms and in the morning the 4-liter tank is full, because it has a high absorption capacity it is a bit noisy.

4 stars exclusively for the noise... it is the most high-quality machine out of all that I have seen in stores and known brands... but with quite a lot of noise even at low settings. I only turn it on when I leave the house.

Purchased in December 2022, around 250 euros, for our vacation home in the city of Lefkada. The apartment is about 70 square meters with a lot of humidity, water runs on the windows and walls (a problem with poor construction when it was built). I had never had experience with dehumidifiers before and I bought this one due to good reviews. I think it does a pretty good job, I put it on automatic mode and it reduces the humidity to desired levels. During the day, while we had it running, there was no water on the walls and windows, but because we closed it at night, we woke up with humidity. The noise is tolerable (much milder than the exhaust fan that drives me crazy) and the tank is a good size (we emptied it once or twice a day with continuous use). I believe I made a good purchase. Time will tell.

I gave it 3 stars because it is very noisy. It is by no means suitable for a bedroom. In the living room and far away, otherwise it is bothersome. Other than that, very good construction with easy handling. After 2 years of daily operation in the bathroom, I can say it is a monster of reliability!

I only have good things to say. It reduced the humidity in my house from 80 to 40 in just three days. I highly recommend it without hesitation.

I was very skeptical but I was proven wrong. The dehumidifier is amazing. The little noise it makes is manageable. You can feel the difference. And the company is very helpful

I have had it for 40 days, it is aesthetically pleasing, it removes humidity as it should, one negative aspect is that sometimes the plastics creak, and also in the clothes drying program, in the 4 hours that I left it in a small space to dry a clothes rack, I did not see any results.

Flawless..!! Really Value for money. I have been saved since the day it arrived at home. Especially during such a time when we are forced to hang clothes inside the house. It fully covers 56 sq.m.

I bought the Qualis 20L for a 200-year-old stone-built house in Ano Potamos Aegiali Amorgos. The worst environment for a dehumidifier. The house only sees the sun on the terrace for a few hours in the summer... In the past, when I occasionally slept there because I permanently lived elsewhere, the humidity would hurt my throat... Now I live there permanently and the machine works constantly for the second winter... When I turn it on after emptying the water, it shows a reading from 83 to 92!!! Then it goes down to 63 because there is no heating. If I had chosen zeolite, it would definitely go lower because temperature doesn't affect it, but this one has low electricity consumption. There has definitely been a great improvement... I empty the 4-liter container three times a day... The noise from the engine can't be heard, only the sound of the air blowing from the outlet, which is pleasant and discreet. Very satisfied!

I am completely satisfied! I would recommend it for purchase. I have already recommended it to relatives and friends.

Detached house 120sqm, walls dripping with water and mold everywhere, reduced humidity from 80 to 50 within 4 days. The best purchase, I wonder why I hadn't bought a dehumidifier for so many years and this one is the best ever choice. I don't understand why some people mention the noise, it's barely audible, not at all annoying, it's like it doesn't exist. The change in temperature sensation in the house is amazing, highly recommended

I have it since 24/12/219 when its price was 176€.
For 3 years I have opened it 3 times to clean it because it collects a lot of dirt. So far it works without any problems. It cannot be completely silent because the fan is large and the compressor can be heard when it is running, and this is normal.

For a 60sqm area, it personally satisfies me, but you should know that when the temperature drops to around 15-16 degrees, it cannot do anything, and this is normal.
In general, it is not suitable to sleep next to it, even at the lowest fan speed.

The good thing is that it opens easily for cleaning from the inside. There are 5-6 screws and the plastic parts have still held up after 3 years and 3 times of opening it, without breaking.

As a machine, it seems to be of good quality.
BUT IT MAKES NOISE
NOISE
Honestly, I wonder why some people say it is quiet and doesn't bother. At the lowest speed, it makes as much noise as the extractor fan.
It has nothing to do with it being an air conditioner.
It doesn't sound like it's broken.
The power of the air can be heard

The dehumidifier is used in a 75sqm house. I don't know why many people complain about the noise when it is actually quiet. It has many functions and fully serves the space in a house where the humidity level is 88%. I highly recommend it, especially if someone is familiar with the company, as it is the only company that manufactures only dehumidifiers and is top of its kind.

Perfect machine, impeccable construction. I have had it for 2 years, I am completely satisfied and I highly recommend it. The fan noise is at very good levels as we are talking about a machine that works with blades and such machines cannot be "silent", as some people are looking for. One of the most value-for-money machines in its category that outperforms all the branded ones in the market.

Excellent dehumidifier. Definitely worth its money. Our house is on an island and every 2 days the container fills up due to humidity. With power outages, it automatically turns on by itself in the previous set mode, so even if I'm away from home, it continues to work normally! I am completely satisfied and I did not regret the money for a moment.
