Customer feedback is generally favorable about adding moisture, quiet operation, performance, mist-free use and adjustable settings. These reports may be relevant if you want routine home humidification, but they are customer impressions rather than measured performance. Water use is mixed: one report mentions refilling every couple of days, while another describes up to 9 hours of humidity. That variation matters alongside the listing's claim of up to 24 hours from a full 6L tank.

Positive themes

Feedback also praises mist-free operation, performance and adjustable settings.

Mixed feedback

Water consumption receives mixed feedback, including a report of needing to refill every couple of days.
