How Does an Evaporative Humidifier Work?
An evaporative humidifier increases humidity by naturally evaporating water into the air, rather than producing visible mist.
Blueair humidifiers use advanced evaporative technology to deliver clean, mist-free humidity without white dust or over-humidification.
How Do Blueair InvisibleMist Humidifiers Work?
- Dry air is quietly drawn into the unit
- Water is pumped from the tank to an anti-microbial wick filter
- Air passes through the moistened filter
- Only the moisture the air can absorb is released back into the room
Because evaporation is self-regulating, the system:
- Prevents over-humidification
- Maintains balanced humidity levels
Works safely in bedrooms and shared spaces
- Dry air is quietly drawn into the unit

More about InvisibleMist Technology
All Blueair humidifiers use InvisibleMist™ technology, meaning:
- No fog
- No wet floors or furniture
- No white dust from minerals
The moisture disperses instantly into the air—cleanly and evenly.
Maintaining Your Humidifier
Any humidifier that uses water can develop mineral buildup over time, especially in areas with hard water.
Regular maintenance helps:
- Preserve performance
- Prevent mineral buildup and odors
- Extend the life of the wick and internal components
Blueair humidifiers are designed with accessible components to simplify cleaning and wick replacement.
- No fog

What Makes Blueair’s Pump System Different
Unlike basic evaporative humidifiers that rely on passive soaking, Blueair uses a precision water pump to deliver the right amount of water to the wick.
This design:
- Separates the water tank from the wick for cleaner operation
- Helps reduce mineral buildup
- Keeps the wick fresher longer
- Improves hygiene and performance consistency
Combined with the automatic drying feature, this system minimizes cleaning time while ensuring cleaner humidity output.
