Blueair's advanced InvisibleMist™ Technology delivers clean moisture by trapping water impurities in the wick filter, releasing pure water vapor with no mist into the air².

We recommend every 6 months. The filter indicator on the interface of your humidifier and in the Blueair app will notify you when it is time to replace your filter.

Your humidifier will deliver up to 48 hours** of clean moisture. Runtime is based on 77°F & 50% RH in night mode. Actual runtime may vary with different room conditions.

No you don’t! Thanks to the anti-microbial filter, you can use tap water with confidence as it traps minerals & pollutants.

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.

Extra long press the Fan Speed button for about 15 seconds until all the LEDs on the interface light up, then release.

The red filter replacement indicator will blink three times and then disappear.

Reminder: After replacing the filter, it is required to manually conduct a filter reset on the air purifier.
