  • FAQs

    Question: When do I replace my filter?

    Answer: In general the wicking filter will last 1-2 months depending on water quality and usage. Any of the following conditions indicate that it is time to replace the Wicking Filter:

    -A buildup of impurities and minerals on the Wicking Filter (evidenced by discoloration of the Wicking Filter)
    -An appreciable decrease in Humidifier output. Please keep in mind if your relative humidity is high your humidifier will put out less moisture
    -The top surface of the Wicking Filter is not moist to the touch
    -The Wicking Filter has large holes or tears

    The Wicking Filter should be replaced at least one or two times during the season, depending on usage, mineral content of the water and the environment. We encourage you to only use a Honeywell HAC-504AW Replacement Wicking Filter. The use of other Wicking Filters may lead to sub-standard performance.
