What to know before buying

Listing details to confirm

Listing details are inconsistent: 60-hour runtime is presented alongside no operating-mode condition, while the feature text says the 6-liter tank runs for days. The claimed 500ML/H output, 550-square-foot coverage, and humidity accuracy are manufacturer specifications, not independently confirmed. Check performance claims against your intended room and settings.
