Pouring from the top

Tank sizes in the samples range from 2L up to 17L, with 3.5L, 3L, 4.2L, 5L, 6L, 7L, 8L, 9L, and 13L also present. A 2-pack of 3.5L units appears in the observed set. Larger tanks mean longer runtime between fills, which matters more when the unit stays in one room.

What comes with the fill opening

Samples pair top-fill with essential oil diffusers, night lights, and auto shut-off. One model lists a water filter and PP material. Another sample is a dual 200S smart humidifier in blue. A 3.5L sample claims a 40-hour runtime.

Quiet and mist behavior

Cool mist and ultrasonic vaporizer language shows up across the samples. One sample lists 24dB operation. Quiet operation is a recurring claim, and auto shut-off appears on several models. Night lights are common, often with multiple colors.

Where the feature stops

Top-fill changes how you add water, not how the unit makes mist. A 2L tank still needs more frequent refills than a 13L or 17L tank. The samples do not show top-fill units with warm mist or steam output.
