We got a dehumidifier as our house doesn't have great ventilation and we tend to steam veg when cooking abd that doesn't help. After a lot of research we got one as it was meant to be quiet so we could leave it on. Yes it really is quiet if you have earplugs and ear defenders on! There is no way you could have it on at night even when it is in a different room you can hear it. I think the people who reviewed and those that write the data sheet all have hearing aid batteries on subscription.
Same for hotel air-con systems - can they be noisier?
