Keep your humidifier running efficiently with a 2-pack of replacement wick filters designed to support steady, even humidity output throughout the room. The woven honeycomb structure increases the water surface area for maximum absorption, allowing air to naturally charge with moisture as it passes through the wick. The filter also helps absorb minerals and calcium from water to support efficient operation. For best results, clean the wick regularly by soaking it in a cleaning solution once per month for 2 hours, then rinsing thoroughly with cold water. Replace at the beginning of each season and then every 2-3 months depending on usage and water hardness.
