Aprilaire 500M Whole-House Humidifier for Homes up to 3,600 Sq. Ft.

In 1954, AprilAire made a groundbreaking move by introducing the first evaporative humidifier tailored specifically for forced air furnace systems. Since then, the company has consistently set the standard in the realm of whole-home humidification solutions.

Our evaporative humidifiers utilize an innovative system where water is directed into a distribution tray at the top of the unit. This tray is uniquely designed to ensure even water distribution across its entire width through a carefully engineered outlet system. Gravity plays a key role as the water cascades over the Water Panel evaporator. As hot, dry air from your HVAC system passes through the moisture-rich evaporator, natural evaporation occurs, converting water into vapor, which is then circulated throughout your home as humidified air.

WHAT’S INCLUDED IN THE PACKAGE: Inside the box, you will find detailed installation instructions and a template, the humidifier complete with a built-in bypass damper, a 24 VAC transformer, a manual humidifier control featuring an integrated sensor, a saddle valve, a solenoid valve, and the Model #10 Water Panel.

PURCHASE WITH CONFIDENCE: Manufactured in the USA, this humidifier reflects AprilAire's commitment to quality and innovation as the original inventor of the whole-home evaporative humidifier. We pride ourselves on being leaders in indoor air quality solutions.

COVERAGE CAPABILITY: Designed to accommodate homes up to 3,600 square feet, our humidifier has an impressive capacity of 12 gallons per day, ensuring full coverage even in tightly constructed houses.

MANUAL CONTROL: The humidifier is equipped with a manual control system that incorporates a single sensor to monitor indoor relative humidity. This feature allows you to easily set and adjust the desired humidity levels in your home.

ENHANCED COMFORT AND PROTECTION: Using our humidifier not only increases your comfort levels but also helps protect valuable items in your home that are vulnerable to damage caused by fluctuating humidity or excessively dry conditions.

HEALTH BENEFITS OF HUMIDITY: AprilAire Humidifiers play a crucial role in maintaining optimal humidity levels of 40% to 60% within your home. This range has been shown to significantly decrease the risk of respiratory infections and can alleviate symptoms associated with allergies and asthma by reducing the growth of bacteria, viruses, fungi, and dust mites. Thus, you can enjoy a healthier living environment while also safeguarding your belongings from the damaging effects of extreme humidity changes.

In summary, since introducing the first evaporative humidifier over six decades ago, AprilAire has maintained its position as a leader in the industry. Our products not only enhance comfort within your home but also promote a healthier indoor environment, ensuring you and your loved ones can thrive amidst the ideal humidity conditions.
