Help your humidifier work the way it is meant to simply by replacing the filter. Humidifier filters need to be changed every 30-45 days, based on usage and water hardness.

Replace your old wick humidifier filter with this replacement humidifier filter to keep your humidifier running the way it should.

Over time humidifier filters become worn out, meaning they cannot create as much humidity and they also start to allow algae, bacteria, and fungus to grow inside your humidifier. This replacement wick filter stops the growth of these harmful things, while keeping your humidifier running better.

This wick humidfier filter fits a variety of models of humidifier, including those made by manufacturers including Gerry, Holmes, and White-Westinghouse.
