Spec, translated

The 9L tank means you might only refill it twice a week instead of daily, but the 300mL/hour output is only average, sufficient for a large bedroom but not an entire open-concept living area.

Lab notes

The observations that actually change the buying decision.

The 9-liter tank is the main selling point, offering genuine multi-day runtime on low settings, which few competitors at this price can match.

Its built-in humidistat is located on the unit, meaning it measures the moist air next to the output, not the room's actual ambient humidity. This makes 'auto mode' functionally inaccurate.

As an ultrasonic unit, it will aerosolize any minerals in your tap water, depositing a fine white dust on surfaces. Using distilled water prevents this but adds to the operating cost.

The 300mL/h max output is adequate for a large bedroom but will struggle to service the claimed 550 sq ft if the space is open or has high ceilings.

Why you should buy

This is for someone prioritizing maximum time between refills over all else. If you want basic app control and a huge tank for a low price, and are disciplined about weekly cleaning, the value proposition is strong.

Why you should skip

Anyone unwilling to commit to a strict weekly cleaning schedule for the large tank should avoid this. Users who want a reliable 'set-and-forget' auto mode will be frustrated by the inaccurate onboard sensor.
