• EVAPORATIVE WICK PERFORMANCE: This humidifier filter replacement draws water upward through layered wick channels, creating a broad wet surface that supports natural evaporation when used with the humidifier's airflow.
• LAYERED WICK STRUCTURE: These humidifier filters feature L layered paper channels and a reinforced round structure. The wick helps retain some mineral deposits from the water while maintaining steady moisture distribution.
• SIMPLE CARE AND REPLACEMENT: Inspect the HAC-504 humidifier filter regularly and replace it when it becomes stiff, discolored or covered with visible mineral buildup. Typical replacement is every 1-3 months, depending on water quality and operating time.
• CHOOSE YOUR VARIATION: Available in white or blue and in 4-pack or 6-pack options. White filters measure approximately 9 × 5.1 inches, while blue filters measure approximately 7 × 5.1 inches. Select the correct color, size and quantity before purchasing.
