What to know before buying

Listing details to confirm

The 100-hour runtime is specified for low mode, and the 800-square-foot coverage, 350mL/h output and noise figures are listing claims rather than independently verified performance. The listing gives both <35db Quiet and 35dB Quiet, so the exact noise figure is inconsistent. It also describes an aroma diffuser and essential-oil pad, but does not clarify whether oils are added to a separate pad or tank. Check the selected listing for how the aroma feature is used.

Aggregate ratings are strongly positive, with five-star ratings making up most of the reported distribution and the rest in the four-star category. No written customer-feedback summary is available, so these ratings do not identify specific strengths, concerns or performance reasons. Consider them alongside the listed capacity and mode-specific runtime claims, which are not customer feedback or independently verified measurements.
