Questions about this item

How do I set up the top-fill tank and what is the common mistake to avoid?

Remove the top cover, pour water directly into the 3L tank, and replace the cover. The common mistake is trying to flip or disassemble the base instead of using the top opening.

What parts will need cleaning or replacement over time?

The BPA-free water tank and wide opening require regular cleaning to prevent mineral buildup; no replaceable filters or wicks are used in this ultrasonic design.

How long will it run continuously on a full tank before the auto shut-off activates?

The 3L tank provides up to 25 hours of continuous mist for rooms up to 300 sq. ft.; the unit shuts off automatically when the water runs out.
