FAQ

What model is this filter compatible with?

This filter is compatible only with the InvisibleMist™ Humidifier.

What is InvisibleMist™ technology?

How often do I need to replace the wick filter?

How long will the Blueair Humidifier run for?

Do I have to use filtered water in the Blueair Humidifier?

Why is the low water indicator on my humidifier not turning off even though I have added water to the tank?

If the low water hasn’t turned off after filling the water reservoir, manually adjust the fan speed on the humidifier by pressing the fan speed button on the device or through the app.

This will draw water into the pump and allow the sensor to detect the recently added water. The low water indicator will then turn off, and you can set the fan back to your desired speed or return to Auto mode.

I've replaced my filter, now how do I reset the filter replacement indicator?
