Frequently asked

What is the HAC-504?

The HAC-504 is a Honeywell humidifier portable wicking filter that fits 56 models in our data.

Is the HAC-504 a wick or a furnace pad?

The HAC-504 is a portable-humidifier wicking filter, not a furnace water panel.

How often should I replace the HAC-504?

We don't have a manufacturer-listed replacement interval for this filter - a common default is once per humidifying season.

Is a cheaper compatible filter as good as the OEM one?

A compatible wick or pad that physically fits isn't automatically equivalent - check reviews for real-world fit and how well it wicks water, since humidifier filters aren't independently certified the way NSF-listed water filters are.
