Let’s talk about performance.

The Aprilaire 700 Humidifier stands out as an impressive whole-house humidifier, boasting a range of features that contribute to its efficient performance. One of its notable attributes is its high-capacity design, positioning it among the top-tier in-duct humidifiers available.

The evaporative humidifier installation on the hot air supply plenum of the HVAC system, as opposed to relying on the HVAC blower, is a smart approach that ensures controlled humidification without straining the existing system.

The built-in fan’s role in drawing in dry air from the furnace enhances its capability to provide consistent humidity levels throughout the home. The inclusion of a built-in drain prevents water accumulation due to mineral buildup and adds a practical touch, underscoring the appliance’s attention to long-term usability.

The operational mechanism of the Aprilaire Humidifier is grounded in a natural evaporation process, offering a simple way to humidify even the biggest of homes.

The water distribution system channeled through a distribution tray and Aprilaire’s patented Water Panel evaporator, ensures even and efficient humidification. The resulting moistened air is then circulated throughout the entire home via the HVAC system’s return duct.

Both models of the Aprilaire 700 humidifier include clear and easy-to-follow instructions for setting and adjusting the air from your HVAC system to deliver optimum humidity in your home.

Additionally, the humidifier’s Water Panel Change indicator adds to its user-friendliness by notifying users when it’s time for a replacement. This proactive feature simplifies maintenance, ensuring that the humidifier continues to operate optimally and effectively. 

Finally, this Aprilaire humidifier isn’t solely reliant on your furnace. Regardless of your home’s heating needs, this versatile unit operates autonomously or in conjunction with your furnace, ensuring consistent comfort in humidity levels year-round.

As if that weren’t enough, the humidifier can also incorporate an external sensor to intuitively detect outdoor humidity, seamlessly fine-tuning your indoor environment.

It intelligently compensates for changes in humidity caused by door and window openings or the natural porousness of some homes.
