Purchased [this](https://www.amazon.co.jp/dp/B092TYLNB3?language=en_US&th=1) sort of expensive compressor dehumidifier off amazon recently, and after running it for over two weeks at max power, not even a single drop of water or any form of condensation has accumulated in it’s bucket. I’ve read in the user manual that the room temperature itself needs to be over a certain temperature to work effectively, but it’s in the same room as my AC unit providing ample heat, so that definitely shouldn’t be a problem. It also said that on “auto” mode it won’t dehumidify under a certain percent of humidity, but it *should* still dehumidify endlessly if on standard mode, from what I understand.
Other strange things I’ve noticed are that the humidity reading on the unit seems to go up a bit strangely when running(as opposed to going down), random tiny squeaking noises, and that the unit will randomly start making loud “chugging” noises for a sustained period of time, before going back to it’s normal volume a while later. The reviews on amazon seem to be largely positive, and the room *does* seem to be a bit drier (although that could just be from the changing weather) so I’m a bit conflicted on my thoughts with this thing.
My dehumidifier back home definitely collects water slower in the winter months, but it still needs to be emptied eventually. I’m wondering if I am somehow missing another point unique to Japanese dehumidifiers, or maybe if I just have a bad unit. Surely, after two weeks of non stop operation at max volume, there would be at least some condensation produced, right? Unfortunately, I only have a couple more weeks before the return deadline comes for this, so I won’t have time to test it more during the rainy season when it will surely be needed.
I am aware that it’s the “dry” season right now in Kanto, and that most people use *humid*ifiers during this time, but for a multitude of reasons I prefer to keep things *reeeaaally* dry for myself. Back home I would be comfortable being in a room with 35% humidity, for example. Interested to hear the thoughts of those of you who might have had (or are having) experience with Japanese dehumidifiers, and could provide some helpful insight. Should I err on the side of caution and exchange it for another unit, or should I avoid the hassle and take a chance and hope it actually will work once it becomes more humid?

Screw that weakling; get a Corona dehumidifier and start filling buckets of suck juice like a king.
I laugh during the rainy season as I launder (and wholly dry) jeans, sheets, and towels with impunity.
That thing is making a mockery of you.

This will put you back on top where you belong.
Probably not the case here but just in case… lots of people discover that there’s a plastic covering that needs to be removed from the air filter, etc.

etc.
I think I can only set mine down to 40%, at least the one that has numerical settings. Do you have a separate hygrometer you can reference, I have a couple combo clock/thermometer/hygrometers which are really handy.
What’s the humidity in your place right now? Actually, if you don’t want to spend a couple dollars getting one of those devices to measure humidity, why don’t you hang up some wet laundry right next to it? If the thing can’t suck any water out of the air when you have laundry 20 cm away, it’s worthless.

Since you don’t really need it now, why don’t you just return it and buy one when it actually does get humid? Then you’ll be able to see if it really works at that time.
It’s probably too dry in your apartment. I have the same model I think, and on auto it targets 60% humidity. So anything below that it stops and just kinda blows clean air. Above that it’ll chug and start working. No point to using it now in winter with the air con running. Your room is already super dry. Try again without the air con on or on a rainy day. It’ll work. Or put it in a room with your washed laundry to dry it.
You can also just set it to weak or strong mode and it should just dehumidify all the time. Even below 60%, but probably not below 40% because that’s just too dry to realistically work well. But again it’s winter and if you have the air con on it’s probably not going to get much water if any, because there isn’t any in your room/home.
Mine worked amazingly during the rainy season, or any humid day. Some days I’ve had to empty the container twice cause it filled with so much water. Used it to dry clothes inside when it was too wet outside. You can run it as a heat source as well without the air con in spring and fall, because the way it takes moisture out of the air it puts out warm air. In summer you probably don’t need it as your air con blowing cold air and “conditioning” it will bring the humidity down.
It’s not going to continue to dehumidify when it’s already below the minimum threshold of humidity. It’s designed to keep the humidity at a comfortable level for humans. It’s not going to dehumidify until it’s like 20% humidity
Do you have the heating on the ac? If so then yeah you ain’t getting any drops in that dehumidifier . I thought the main purpose of these dehumidifiers was to stick it in a small room where wet clothes are hanged up.
The cheap ohyama does it for me. Gets full in hours but never ran it in mid winter so not sure if that would help your wished for levels of humidity.
