BLUEAIRH35i Humidifier Gen 2

Q: What is InvisibleMist technology?

Blueair’s InvisibleMist Technology adds clean moisture to the air without the mess that comes with visible mist.

Q: How often do I need to replace the wick filter?

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.

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

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

Q: How do you refill the Blueair Humidifier?

First, turn off your humidifier. For top-fill model, gently pour water into the top until it reaches the max fill line. For bucket-fill models, remove the tank, fill it with water, and pop it back in place. Once it’s filled, turn it back on.

Q: How long will the Blueair Humidifier run for?

The humidifier can run up to 48 hours but will vary depending on the mode, room size and temperature.
