I tried several humidifiers, this one is fairly quiet, let say you will not find more quiet, I think we just sleep with by cons do not put it up because when we entent too much of clapottis water, for most against in almost hear the water if we decrease the steam flow rate, it is still enough to sleep now be aware that if you put the maximum of its flow, this one is awesome !!! but for the day of course. Anyway, try, amazon allow to test for a month and reimburse you in the event of dissatisfaction, just 2 euros will be taken for the cost of return so ... There are two type of humidifier, those has hot steam and ultrasound has those, I deconseille you hot steam because too noisy, this one is a cool mist, and more safe to burn for children
