Aprilaire 4792 Humidifier Maintenance Kit for Whole-House Models 500, 500A, 500M

In 1954, AprilAire launched the very first evaporative humidifier designed specifically for forced-air furnace systems. Since then, AprilAire has remained at the forefront of the industry, continuously innovating whole-home humidification solutions. Their evaporative humidifiers work through a systematic process that begins with water being piped into a distribution tray located at the top of the unit. This water is evenly spread across the tray’s width via an expertly engineered series of outlets. Thanks to gravity, the water cascades over the Water Panel evaporator.

As dry, heated air from the forced-air furnace passes through the moist Water Panel evaporator, natural evaporation occurs, transforming the water into vapor. This process results in humidified air that is then circulated throughout your home.

The AprilAire 4792 Humidifier Maintenance Kit is your all-in-one solution for caring for your AprilAire Whole Home Humidifier, specifically designed for models 500, 500A, and 500M. You can purchase this kit with confidence, knowing it is a genuine product manufactured in the USA by AprilAire—the original creator of the Whole Home Evaporative Humidifier and a leader in enhancing indoor air quality. This kit aims to optimize your humidifier’s performance, restoring it to like-new conditions.

What makes this maintenance kit particularly convenient is that it includes all the necessary components to maintain the peak functionality of your AprilAire Whole Home Humidifier. There’s no need to hunt for individual parts; everything is bundled together for your ease. As a best practice, it is advisable to consult the Owner's Manual that comes with all AprilAire Humidifier Maintenance Kits before starting any maintenance tasks.

The maintenance kit consists of essential items: a Water Panel (10), a Scale Control Insert (4640), a Water Distribution Tray (4331), a Feed Tube with Compression Sleeve and Nut (4335), a Yellow Orifice (4231), an In-line Strainer (4004), a Drain Spud (4223), and the Owner's Manual.

For those aiming for optimal performance, it is essential to note the Water Panel's precise dimensions: 9.75 inches in height, 9.5 inches in length, and 1.75 inches in width. To ensure your humidifier operates at its best, it is recommended that the water panel be replaced annually.

Maintaining the proper humidity level in your home is crucial for your health. AprilAire Humidifiers help sustain indoor humidity between 40% and 60%. This range has been shown to decrease the likelihood of respiratory infections and alleviate allergy and asthma symptoms by curtailing the growth of bacteria, viruses, fungi, and dust mites. Moreover, balanced humidity levels enhance your comfort and protect your belongings from damage caused by significant fluctuations in humidity or overly dry conditions.

Embrace the benefits of an AprilAire humidifier to optimize your indoor environment, ensuring both well-being and comfort for you and your family.
