Price Comparison
The Aprilaire 700M Whole-House Humidifier is priced at C$615.88, while the AprilAire 720MKZ Whole House Fan Powered Evaporative Humidifier is more expensive at C$817.99. The price difference of C$202.11 reflects the additional features and capabilities of the 720MKZ model. For consumers on a budget or those with smaller homes, the 700M offers an attractive entry point into whole-house humidification. However, those willing to invest more may find the advanced features of the 720MKZ justify its higher cost.
Humidification Capacity
When it comes to humidification capacity, the AprilAire 720MKZ outperforms the 700M significantly. The 720MKZ delivers an impressive 21 gallons of humidification per day, making it suitable for larger homes and faster moisture balancing. In contrast, the 700M has an evaporation capacity of 0.75 gallons per hour, which translates to approximately 18 gallons per day. This means that while the 700M can adequately humidify a home of up to 4,200 square feet, the 720MKZ is better suited for more substantial spaces, providing quicker and more efficient moisture distribution.
Design and Installation
In terms of design, the AprilAire 720MKZ offers more flexibility with its reversible design, allowing the fan module to be configured for tight installations. This adaptability can be crucial for homeowners with specific space constraints. The installation is made easier with the 720MKZ's distribution tray, which allows it to be installed up to 3 degrees off level. While the 700M is fan-powered and designed for straightforward installation, it lacks the advanced features that make the 720MKZ more versatile in challenging environments.
Sustainability Features
Sustainability is a significant aspect where the AprilAire 720MKZ shines. It is designed to produce 60% less wastewater compared to the 700M, thanks to its innovative recirculation valve that recycles water, enhancing performance while reducing waste. This eco-friendly approach not only benefits the environment but can also lead to savings on water bills. The 700M does not have such sustainability features, making the 720MKZ a more attractive option for environmentally conscious consumers.
Maintenance
Maintenance is a crucial aspect of any humidifier, and the AprilAire 720MKZ simplifies this task significantly. It features a one-piece HydroCore water panel disposable cartridge, which allows for quick and easy replacements. This design is made with recycled plastic, emphasizing the model’s sustainability. On the other hand, while the 700M is also designed for ease of use, it doesn't offer the same level of maintenance convenience as the 720MKZ. For those who prioritize low-maintenance solutions, the 720MKZ stands out.
Control Options
Both humidifiers include manual control, but the AprilAire 720MKZ takes it a step further. Its manual control system is conduit or wall mount compatible and provides dry contact closure, allowing for more precise humidity management. This level of control can be crucial for maintaining optimal indoor air quality. In comparison, the 700M’s manual control is straightforward but less advanced. For users who appreciate sophisticated control features, the 720MKZ will be the more appealing choice.
Warranty and Brand Trust
Both models come with a 5-year manufacturer warranty, which is a testament to the quality and reliability of Aprilaire products. Consumers can buy either product with confidence, knowing they are backed by a reputable brand that has been a leader in indoor air quality solutions since 1954. This warranty period is standard for the industry and reflects the durable construction of both humidifiers. However, the 720MKZ, with its more advanced features and capabilities, may provide greater peace of mind for those investing in a premium model.
Which should you buy?
The choice between the Aprilaire 700M Whole-House Humidifier and the AprilAire 720MKZ Whole House Fan Powered Evaporative Humidifier largely depends on your specific needs. If you have a smaller home and are looking for a budget-friendly option, the 700M is a solid choice at C$615.88. However, if you require a high-capacity humidifier for a larger space, and you're willing to invest C$817.99, the 720MKZ offers superior performance, sustainability features, and easier maintenance. Ultimately, consider your home's size, your budget, and your prioritization of advanced features when making your decision.
