"A feature-rich humidifier for a low price, if you accept the risks of a generic, no-name appliance."
The 7L tank is genuinely large, but the 'up to 60 hours' runtime is marketing math for the lowest setting. Expect to refill it daily if you're using it on high to actually humidify 500 sq. ft.
This is for a buyer who prioritizes a low upfront cost and a rich feature set like app control and a large tank. It's a fit if you are willing to use distilled water and perform the necessary weekly cleaning regimen.
Anyone unwilling to commit to a strict weekly cleaning schedule should avoid this, as all ultrasonic humidifiers can breed bacteria. Users who expect customer support or long-term reliability should invest in a product from an established brand.
