If You’ve Never Changed Your Humidifier Filter, You Need to Do It Now — Here’s Why
Humidifiers soften the air and help you feel more comfortable during the driest season of all: the heating season. Yet a humidifier is only as effective as its filter.

How Often to Change a Humidifier Filter
The type of humidifier you own—whether a large or small portable humidifier or a furnace humidifier—affects how often you should change the filter.
- Large portable humidifiers: Change the wick filter on evaporative humidifiers four times per year.
- Small portable humidifiers: While there is no need to change a filter, ceramic filters need to be rinsed every 30 cycles.
- Furnace humidifiers: Change the filter once per year at the start of the heating season.
