Good evening. The order arrived promptly, and the dehumidifier is generally quite good. On the first day, it works perfectly. You can attach the wheels included in the package, and be careful when moving it between carpet and tile or children's toys on the floor to avoid it falling during the transition from one room to another.

Impressions:

The brand is one of the most well-known and generally good in terms of air conditioning.

We got the model that is 24 liters per day for a house of about 80 square meters. At first - like everyone - I checked to see if all parts were okay, but I found that it has a - significant - issue with its lid. The openings on the inner lid of the water collection tank (shaped somewhat like nostrils, see the photos) seemed almost clogged with a small plastic crust. Of course, it needs to be open for the water to flow comfortably into the tank. I opened it with a pen cap. That's how it must have come from the factory. Check it if you happen to have one or if you plan to buy one.

Let's move on to the practical part.

So... even without having a dehumidifier placed in the house before, it showed 80% in the living room!!! (You might say, what would it show in December?) Within a short time, it gradually reached 70% and then 60%, and now it is permanently at 50% to 55%. In the living room, it is 55%, while in my room, I want it to be 50%. If it is true that the ideal humidity for a house is between 45% and 55%.

It manages it. It has already filled the water tank once and is nearing the second.

Noise: It does not exceed or even touch the noise of a refrigerator or an air conditioner. If you close your eyes and listen, it feels like you are in a room with a small refrigerator and an air conditioner. Or like a fan on top of a refrigerator, that's how it seems to me. Personally, having had a refrigerator next to a couch where I slept before, this sound does not bother me; rather, it relaxes me. Others might find it bothersome, depending. However, I would say it is quiet; it does not make noise. It is a machine, it runs on electricity, it drains the space of humidity... it will make some "noise."

It's just fine, be careful with the plastic parts, ensure the openings where the water exits are clear, check this as it is important, beyond that, it is a very good dehumidifier at a good price.

The Toyotomi Sonzai TDE-16GA20 is a reliable and efficient dehumidifier that stands out for its effectiveness, quiet operation, and ease of use. As an owner of this product, I can say that it has significantly improved the air quality in my home, providing a more comfortable and healthy environment.

### Performance and Power
The Toyotomi Sonzai TDE-16GA20 has a powerful dehumidifying capability, with the ability to absorb up to 16 liters of moisture per day. This makes it ideal for medium-sized spaces, such as living rooms and bedrooms. From the first use, I noticed a significant reduction in humidity and musty odors, making the space more comfortable.

### Design and Functionality
The Toyotomi Sonzai TDE-16GA20 dehumidifier features a modern and discreet design that easily fits into any room. The digital display and user-friendly control buttons make adjusting the desired humidity level a simple task.

I highly recommend this product to anyone looking for a reliable and efficient dehumidifier.

I come from the Meaco DD8L and Morris MDE-24200i. Before I start the review, let me explain something for those interested.
1) There is no silent dehumidifier, whether with a compressor or zeolite. Generally, the noise level depends on the dehumidification capacity, the type of dehumidification, and the quality of the materials used.
2) The power consumption is essentially related to the type of dehumidification (compressor or zeolite) and the dehumidification capacity per twenty-four hours (e.g., this one is 24 liters per day).
3) In zeolite dehumidifiers, the temperature of the room does not matter since they operate correctly even at temperatures close to zero and emit warm air like a small heater, unlike those with a compressor which require a room temperature of at least 16 degrees Celsius to dehumidify and not defrost their motor. So depending on the space (e.g., an unheated storage room or a heated apartment), you choose accordingly.
Regarding this specific one:
POSITIVES: TOYOTOMI! I don't think there's a need to say anything else; anyone who has products from the company can understand their quality.
NEGATIVES: 1) The water collection tank, both in terms of capacity and shape. Its capacity is small for areas with high humidity, resulting in needing to be emptied twice a day if it runs continuously (like mine). You can see the shape; it has indentations, and the lid manages to spill water in 2-3 places during emptying, resulting in you getting wet if you don't know or if you're careless. Also, be careful when removing the full tank from the dehumidifier due to its tall and slim shape.
2) The carrying handles are so small, as you can see in the photo, that there is a high chance it will slip out of your hands if you lift it to carry it, due to its weight. The situation is somewhat saved by the wheels, which have 360-degree rotation, so you can slide it in any direction.

Review for the 20lt model:

I placed it in a basement/warehouse of 115+ sq.m. and within 2 days it reduced the humidity from 65-70% to the limit of 55% with a steady consumption of ~3.5kWh/day (it is connected to a smart Tapo socket). Only in the first 24 hours it struggled a bit and consumed 5-6kWh. It seems to draw a steady power of 240-250w whether the UV is activated or not. The wifi consumes less than 5w, however, if someone doesn't use it properly, they should turn it off using the relevant button as over time they will save something. Measured with at least 5 hygrometers from different manufacturers placed in various locations, which have variances of up to 5% between them, but the reduction in humidity is noticeable overall, as observed in all the hygrometers.

When it reaches its limit, it stops and if I understand correctly, it starts again only when the humidity increases by about 3-4%. However, there have been times when I set it at 55%, it reduced the humidity to 53% and continued to work normally (i.e. at 250w).

In theory, the humidity can go even lower, but I haven't tested it yet. With the limit set at 55% and the current humidity, my tank fills up about 2 times per day, so I will install a drain pipe to send it directly to a drain (note that it doesn't have a motor for water outlet, so the last part must be drained based on the slope of the pipe only). The package also includes a drain pipe of about half a meter (I don't remember the exact diameter, I think it is mentioned in the manual and it is around 14mm or something like that). The tank also has the disadvantage that its lid doesn't close tightly and it leaks from everywhere, so during emptying, the water cannot come out from a specific point. Practically, water runs from the upper edge from all sides and you need to be careful not to make a mess when emptying it.

It is definitely not silent. There is a constant humming throughout the space and when it starts or generally increases its speed, for a few minutes it sounds like the characteristic sound of old refrigerator motors. Also, sometimes it rattles loudly. It doesn't bother me in the basement, but I would never leave it in the living room or bedroom, especially during quiet hours. It makes much more noise than a typical air conditioner or air purifier, etc.

On the plus side, the pre-installed plastic feet can be replaced with wheels (included in the package). The connection and use with wifi are simple, but the Ewpe application is simply unacceptable (possibly the worst of the dozens of similar ones I have tried over time). Most of the time, it returns a timeout error the first time until it manages to connect to the device, it cannot connect to Alexa (the last step always fails even when the relevant skill is enabled), it doesn't send notifications when the tank is full, etc.

Overall, it seems to do the job and is worth its money, however, it can be improved.

ps: I see in the reviews photos with the back of the device almost stuck to the wall. I hope that is not its permanent position because the dehumidifier draws air from the back and the manual recommends a distance of at least 35-40cm both from the back and from its left side, which is the air outlet.

UPDATE after 3 months of use: It does what it's supposed to do. Likewise, it makes noise. I am still trying to understand the difference in settings between High and Low fan, as they practically make almost the same noise and burn almost the same wattage (maybe High burns about 10% more, at most). Generally, I always have it on High and running for 12-18 hours a day, burning over 100-110 kWh per month. I haven't experienced any disconnections from the wifi, although the Ewpe app always times out after 30" before it manages to connect on the second attempt.

But what I really haven't understood is how it starts and stops on its own:
- If you set it, for example, to a humidity level of 55% and it has stopped earlier on its own, then usually it will only start again when the sensor reaches 60%.
- With the same humidity setting, it usually stops when it reaches around 51-52% and often not even then. Because I have been using it exclusively with the internal tank, at some point it would fill up, and the device would stop working for hours (before reaching 51-52%), and once I emptied the tank, the device would start again on its own. So far so good. The problem was that it would do this even when it measured the humidity at 53-54%, which is below the 55% that I have set. It shouldn't start in that case.
- Lately, I have connected it to a drain. Although its setting is still at 55%, it practically never stops working. It reduces the humidity to 47-50% according to 4-5 hygrometers scattered in the room, but the dehumidifier itself never shows below 52% and obviously, for some inexplicable reason, it doesn't stop. When I tried to increase the setting to 60%, the humidity in the basement exceeded 65% before the device started, so I didn't try it again.

Since the Ewpe app doesn't seem to have a schedule or timer on (only timer off), I had to set a program through Alexa so that it flashes for a few hours a day either automatically or with voice commands. Luckily, at some point, the relevant Ewpe skill of Alexa was activated without me having to do anything (previously it would fail at authentication). So far, I have only done it based on time, but I will try to do the same based on humidity percentages, which Alexa seems to read. So I will be able to turn it on automatically if it reaches, for example, 58% and also turn it off if it drops to 53%. We'll see.
