Wick Filters

Why does my wick filter turn colors?

Wick filters help remove the impurities found in general tap water. These impurities cause the filter to change color as they get trapped in the wick. As more and more minerals become trapped more of the filter will change color. Eventually the filter will no longer be operating the humidifier effectively, which means it is time to change the filter.

What is the average filter life of a wick filter? How often should I change my filter? How do I know my filter needs to be changed?

We recommend you replace your filter every 4-6 weeks, depending on usage and hardness of water. In some evaporative cool mist humidifiers we have included a Filter CheckĀ® indicator that will indicate when the filter needs changing.

How do I store wick filters?

If it is necessary to save the filter, make sure the the filter is completely dry before storing. If a wet filter is stored, it will grow mold and mildew while in storage.
