Manual controls offer straightforward operation, providing a reliable method for adjusting humidity levels without complex programming.

Potential buyers should consider that the 720MKZ relies on manual control, which might not suit those who prefer smart technology or advanced automation. While the noise level is generally low, any fan-powered unit may produce some sound, particularly at higher speeds. Additionally, as it is part of the AprilAire Healthy Air System, users interested in comprehensive indoor air quality solutions might need to invest in additional components for full functionality. In terms of maintenance, while the HydroCore panel is designed for easy replacement, users should be prepared for regular upkeep to ensure optimal performance. Lastly, although it comes with a 5-year warranty, be mindful of its dimensions and weight during installation, as it may require a suitable space within the home.
