AprilAire 4750 Maintenance Kit With 35 Water Panel
Keep your AprilAire Whole Home Humidifier running at peak performance with the AprilAire 4750 Maintenance Kit with 35 Water Panel. This comprehensive kit includes all the essential replacement parts needed for routine maintenance—helping extend the life of your humidifier and ensuring optimal humidity levels throughout your home.
AprilAire pioneered whole-home humidification systems, introducing the first evaporative humidifier for forced-air furnaces in 1954. Today, their technology remains at the forefront, providing comfortable, energy-efficient indoor air quality solutions.
The AprilAire humidifier system draws water into a distribution tray where it flows evenly across the top of the Water Panel. As warm, dry air from your furnace passes through the moisture-rich panel, natural evaporation transforms the water into vapor, which is then circulated through your home—adding comfort while protecting your wood furnishings and minimizing static electricity.
This maintenance kit includes a replacement No. 35 Water Panel, along with all the critical internal components needed for easy DIY servicing.
