Seasonal changes and your local climate greatly affect your home's humidity. For a comfortable and healthy home, aim for a humidity level between 30-50%.
When the air in your home is too moist, it can feel hot and sticky, and it can worsen health conditions like asthma and allergies, making it more difficult to breathe.
On the other hand, when the air is too dry, you might notice dry skin, an irritated throat, or itchy eyes. Low humidity can also damage wood floors and furniture, causing them to warp or crack.
Dry: <30%
Ideal: 30-50%
Moist: >50%
An evaporative humidifier uses a fan to blow air through a moistened wick filter, causing water to evaporate into the air and increase humidity.
The wick filter should be replaced every 6 months. It should be cleaned weekly when in use according to the instructions in the user manual to maintain optimal performance.
Important! When the wick filter is replaced, the Filter Expire Indicator must also be reset. To reset your Filter Expire Indicator:
Important! Turn the humidifier off and disconnect from the power supply before maintenance.
When your humidifier's indicator light turns red, it's time to change the wick filter.
To reset the filter indicator, turn the device on and long press the fan speed button for about 15 seconds, until the LEDs blink 3 times, and then release.
When the wick filter is replaced, the Filter Expire Indicator must be manually reset.
Your Blueair humidifier is safe to use with clean water of your choice, including tap. It is recommended that the water tank be cleaned weakly to ensure proper operation. After refilling press any button to restart.
Option 1: Top Pour (Recommended)

The runtime of your humidifier on a full tank can vary greatly depending on the size of your space and the natural humidity in your environment. We recommend keeping a closer eye on the tank when you first get the humidifier and when seasons change to understand how often replacement is necessary in your space.
If the low water light 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 Blueair 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 see the fan back to your desired speed or return it to Auto mode.
Auto Dry Mode or “Auto Dry” makes life easier by using low airflow to dry out the wick filter after use, so you spend less time cleaning. Your device will automatically switch to Auto Dry Mode 5 minutes after either the water tank becomes empty or the device is turned off.
Note: When turned on, Auto Dry Mode will activate for 2 hours. There is a 5-minute delay before Auto Dry Mode is activated. You can exit Auto Dry Mode or disable this feature in the app if desired. For best hygiene and user experience, we recommend leaving this feature activated.

To clean, remove the wick filter from the filter cage and rinse under running water. For a deeper clean, soak with mild or citric acid cleanser, 20g citric acid for every 1L of water for 1 hour, then rinse well under running tap water according to the instructions in the user manual.
If the water is at the max fill line prior to installing the pump, the slight displacement cause by inserting the pump will not cause an issue.
The Blueair H35i humidifier uses evaporative technology which pulls water molecules from the wet wick filter and dispenses it into the air, there will be no visible mist coming from the device.
Potential Causes:
Ensure that the room the humidifier is operating in is appropriately sized for the device's capacity, ensure doors and windows are closed, and verify the hydrometer is working correctly.
If your device is set to Auto Mode, the target humidity level may have already been reached. Increase the target humidity level or exit Auto mode and use manual operation by selecting a Fan Speed.
