Overview of the AprilAire 720AKZ and AprilAire 500

The AprilAire 720AKZ Whole-House Fan-Powered Evaporative Humidifier offers a higher capacity for humidification compared to the AprilAire 500. With the ability to deliver 21 gallons of moisture per day, the 720AKZ is suited for larger homes, while the 500 provides 12 gallons of humidity per day, making it ideal for homes up to 3,600 sq. ft. This difference in capacity is crucial for homeowners needing to address more significant humidity issues.

The AprilAire 720AKZ is priced at C$871.98, reflecting its advanced features and higher output. In contrast, the AprilAire 500 is more budget-friendly at C$400.00, appealing to those with smaller spaces or lower humidity needs. This price disparity highlights the trade-off between size and cost when selecting a humidifier.

Humidity Control Features

The AprilAire 720AKZ is equipped with an automatic control system that adjusts humidity levels based on outdoor temperature, enhancing its efficiency in maintaining comfortable indoor air. This feature is supported by a digital control panel that showcases the relative humidity percentage, making it user-friendly.

On the other hand, the AprilAire 500 also includes an automatic digital humidistat that actively measures humidity levels and adjusts operation accordingly. This ensures balanced humidity throughout the home, although it operates with a slightly less sophisticated control system than the 720AKZ. Both units provide reliable humidity management, but the additional features of the 720AKZ may offer a better experience for larger households.

Installation and Maintenance

Installation ease is a key factor for both humidifiers. The AprilAire 720AKZ boasts a reversible design, allowing it to fit various furnace configurations with minimal hassle. Its one-piece HydroCore water panel cartridge simplifies maintenance, enabling quick replacement and reducing upkeep time.

Conversely, the AprilAire 500 comes with an installation kit that includes all necessary parts, making it straightforward for homeowners to set up. This kit is advantageous for those who may not have installation experience. While both models are designed for easy installation, the 720AKZ's features may be more beneficial for complex setups.

Environmental Impact and Efficiency

The AprilAire 720AKZ is designed with sustainability in mind, featuring a recirculation valve that reduces wastewater by 60% compared to earlier models. This means that not only does it perform well, but it also conserves water, which is an essential factor for environmentally conscious consumers.

The AprilAire 500, while effective, does not specifically highlight any water-saving features in its description. However, it does emphasize the importance of maintaining balanced humidity to prevent the formation of bacteria and dust mites, which indirectly promotes healthier indoor air quality. In terms of environmental efficiency, the 720AKZ takes a clear lead with its innovative design.

Performance in Different Home Sizes

When considering home size, the AprilAire 720AKZ is capable of serving larger spaces effectively due to its 21-gallon output per day. This high capacity makes it a strong choice for homes with significant humidity needs, particularly in climates where moisture management is crucial.

In contrast, the AprilAire 500 is designed for homes up to 3,600 sq. ft. and delivers 12 gallons of moisture per day. While it may suffice for smaller homes or less severe humidity issues, larger homes may struggle to maintain adequate humidity levels without the more robust performance of the 720AKZ. Thus, potential buyers should assess their home size and humidity requirements carefully.

Warranty and Customer Assurance

Both the AprilAire 720AKZ and AprilAire 500 come with assurances for customer satisfaction. The 720AKZ is part of the comprehensive AprilAire Healthy Air System, which integrates various aspects of indoor air quality management. This system reflects the brand's commitment to health and quality.

The AprilAire 500, meanwhile, is backed by a 5-year warranty, demonstrating the company's confidence in its product's durability and performance. While both humidifiers offer reliable options, the extensive system offered by the 720AKZ may appeal more to those looking for a holistic approach to indoor air quality.

Price Comparison

Price is a significant factor when deciding between the two models. The AprilAire 720AKZ retails for C$871.98, which reflects its higher capacity and advanced features. This investment may be justified for larger homes requiring efficient humidity control and sustainability.

In contrast, the AprilAire 500 is priced at a more accessible C$400.00, making it an attractive option for budget-conscious consumers or those with smaller homes. The substantial price difference indicates that while the 720AKZ offers more features, the 500 still provides effective humidification at a lower cost.

Which should you buy?

The choice between the AprilAire 720AKZ and the AprilAire 500 ultimately depends on your specific needs and budget. If you have a larger home and require advanced features like high capacity, automatic controls, and water-saving technologies, the AprilAire 720AKZ is the better option despite its higher price of C$871.98. However, if you have a smaller space and are looking for an effective yet economical solution, the AprilAire 500 at C$400.00 offers excellent value. Consider your home's size, humidity requirements, and budget when making your decision.
