Sorry to hear your humidifier is leaking. That’s frustrating and definitely not how it should work.
This can happen if the water stopper is not fully or correctly installed. It needs to be seated all the way to create a proper seal. Even being slightly off can cause leaks.
Since this applies to more than one of our humidifiers, we recommend checking the product manual for your specific model. You can find all of our humidifier manuals here.
The manual walks through correct setup step by step and shows exactly how the water stopper should be positioned.
If you check that and still run into issues, contact us here. We’re happy to help get this sorted.
