What to know before buying

Listing details to confirm

The 50-hour runtime and 400-square-foot coverage are listing claims, and actual results depend on operating conditions. The stated 5% humidity-control tolerance is also a manufacturer claim, not an independent measurement. The product description calls the tank top-filled, while the detailed feature list confirms a removable tank but does not separately specify the filling method.
