AprilAire 720AKZ Whole-House Fan-Powered Evaporative Humidifier vs Aprilaire Model 865 Whole House Steam Humidifier with Fan Pack for Radiant Heat

Overview of the AprilAire 720AKZ and AprilAire Model 865

The AprilAire 720AKZ Whole-House Fan-Powered Evaporative Humidifier is designed for larger homes, providing 21 gallons of humidification per day. In contrast, the AprilAire Model 865 Whole House Steam Humidifier is a high-output unit that can add between 11.5 to 34.6 gallons of moisture daily, depending on the installation and voltage used. While both products serve the purpose of improving humidity levels in homes, their approaches and capabilities differ significantly.

Humidification Capacity

The AprilAire 720AKZ excels in delivering a consistent output of 21 gallons per day, making it suitable for larger homes with high humidity needs. On the other hand, the AprilAire Model 865 offers a variable output, with the ability to provide between 11.5 to 34.6 gallons of moisture daily. This flexibility allows it to cater to homes with varying humidity requirements, particularly in tightly constructed spaces. Therefore, if your home needs precise humidity control, the Model 865 may offer more adaptability.

Technology and Design

In terms of technology, the AprilAire 720AKZ features a hybrid fan that enhances evaporative efficiency, ensuring better air distribution and performance. It is engineered with a one-piece disposable HydroCore water panel cartridge for easy maintenance. The Model 865, however, uses electrode technology to create steam, which is then pushed into the living space by a wall-mounted fan, making it ideal for homes without HVAC duct systems. This differing technology highlights the 720AKZ’s efficiency in evaporative humidification versus the Model 865’s steam-based approach.

Installation and Maintenance

The installation process varies between the two products. The AprilAire 720AKZ is designed with a reversible fan module, allowing for flexibility based on your furnace configuration. Its installation accommodates up to a 3-degree level tolerance, simplifying the setup process. Conversely, the Model 865 is intended for homes that might require a bit more complexity due to its steam generation and wall-mounted fan setup. Maintenance for the 720AKZ is made easier with its quick-change HydroCore cartridge, while the Model 865’s maintenance will depend on the specific steam generation components.

Environmental Considerations

The AprilAire 720AKZ has a significant edge when it comes to sustainability, claiming to produce 60% less wastewater compared to its predecessor, the AprilAire 700. This feature is particularly beneficial for environmentally-conscious consumers looking to reduce water waste. The Model 865, while effective in its humidification, does not highlight similar sustainable features, making the 720AKZ a more environmentally friendly choice for those prioritising water conservation.

Performance in Different Climates

The AprilAire 720AKZ is designed to balance humidity quickly, making it a suitable option for various climates, particularly in larger homes. It is part of the AprilAire Healthy Air System, which addresses multiple aspects of indoor air quality. The Model 865, however, is specifically ideal for arid or desert climates, as it can effectively handle the increased moisture demands typical in such environments. This makes it a better fit for homes in specific geographic locations where dry air is a consistent issue.

User Control and Features

The AprilAire 720AKZ comes equipped with an automatic control system that adjusts humidity levels based on the outdoor temperature, providing a level of convenience that many users will appreciate. It also offers a manual mode for those who prefer customisation. The Model 865 does not mention similar automated features, which may limit its ease of use for some consumers. The digital control with a large backlit display in the 720AKZ enhances user experience by clearly showing humidity levels and set points.

Price Comparison

The AprilAire 720AKZ is priced at C$871.98, making it a more budget-friendly option compared to the AprilAire Model 865, which retails for C$1,909.43. This substantial price difference could be a significant factor for consumers weighing the features against their budget. While the Model 865 may offer higher output capabilities, the price point may not justify the cost for all homeowners, especially when the 720AKZ provides substantial performance at a lower price.

Which should you buy?

Choosing between the AprilAire 720AKZ and the AprilAire Model 865 largely depends on your specific needs and circumstances. If you require a more economical solution for larger spaces with the benefit of lower wastewater output, the 720AKZ is a strong contender. However, if your home is situated in a dry climate and needs high-output steam humidification, the Model 865 could be worth the investment. Ultimately, consider your home's size, climate, and your budget when making a choice.
