General Information

Can I run my unit without a filter?

Evaporative Cool Mist humidifier cannot be run without the use of a wick filter. However, ultrasonic and warm mist humidifiers that use a water purification filter can be used without the filter.

What are the charcoal filters for on the Evaporative Humidifier?

The filters are designed to remove particles, such as airborne dirt and dust, and to help provide cleaner humidified air.

Does water quality affect filter life?

Yes, absolutely. The harder the water, the shorter the filter life. This is because minerals will get trapped in the filter over time and cause the filter to lose its ability to wick.
