"A huge tank and external sensor offer rare intelligence at a budget price."
The 350ml/hr mist output is adequate for maintaining humidity in a large bedroom, but it will struggle to quickly raise humidity in the claimed 500 sq ft open-plan space.
This is for the user who prioritizes long runtimes and automated control over all else. The massive tank and external humidistat create a 'set and forget' system that requires infrequent refilling, ideal for bedrooms or offices.
Anyone with hard water who is not prepared to exclusively use distilled water should skip this. Users needing to humidify a truly large, drafty room should seek a unit with a higher output (500ml/hr or more).
