Aprilaire 4839 Humidifier Maintenance Kit with Water Panel Model No. 35 Replacement Filter for Whole-House Humidifier Models 600, 600A, 600M

The year 1954 marked the introduction of the first evaporative humidifier for forced air furnace systems by AprilAire. Since then, AprilAire has remained the industry leader in whole home humidification systems.

Our evaporative humidifiers operate by channeling water into the distribution tray at the top of the unit. The water is evenly dispersed across the width of the tray through a scientifically engineered system of outlets. Gravity then guides the water over the Water Panel evaporator. Dry, hot air from the forced air furnace passes through the moisture-laden Water Panel evaporator, where natural evaporation occurs, transforming the water into vapor. This humidified air is then circulated throughout your home.

This AprilAire 4839 Humidifier Maintenance Kit contains all the necessary components for step-by-step maintenance of your AprilAire Whole Home Humidifier, models 600, 600A, and 600M.
