The AprilAire 800 Whole-House Steam Humidifier is designed to provide robust humidity control for homes up to 10,300 square feet. One of its standout features is its impressive humidification capacity, delivering between 11.5 to 34.6 gallons of moisture daily. This makes it ideal for larger homes or those in climates that require significant humidity adjustments. The automatic operation, with dual sensors, allows for 24/7 monitoring and adjustment to maintain optimal humidity levels, adding convenience for users who want to set it and forget it.

A notable strength is its electrode technology, which eliminates the need for purified water, reducing installation complexity and maintenance costs. This is a big plus for homeowners who want a straightforward solution without frequent upkeep. Additionally, maintaining humidity levels between 40% to 60% can help alleviate respiratory issues and preserve the integrity of household items sensitive to dry air.

The humidifier does require some assembly upon installation, which may be a bit of a hurdle for those less handy. While the noise level is not specified, steam humidifiers can sometimes be noisier than other types, so it's worth considering if noise is a concern in your living space. Also, its size and weight (23 pounds) may pose a challenge for installation in certain locations. With a focus on efficiency and health benefits, the AprilAire 800 is well-suited for larger homes that require effective humidity management.

This makes it an environmentally friendly choice compared to older models like the AprilAire 700.

Maintenance is simplified with the one-piece HydroCore water panel, which is easy to replace annually, although some may find it inconvenient that it requires annual replacement. The humidifier's noise level is low, which adds to the comfort of use without causing disruptions at home.

The reversible design of the fan module offers flexibility for various furnace configurations, making installation easier in tight spaces. Additionally, features like the distribution tray that accommodates slight installation misalignments, and leak prevention measures, add to the product’s reliability.

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.
