Overview of the Products

The Aprilaire Model 700 Automatic Whole House Power Furnace Humidifier is priced at C$598.00, while the DIGI MISTER Whole Home Oven Humidifier offers a more budget-friendly option at C$302.61. Both products aim to improve indoor air quality by adding moisture, but they cater to different needs and preferences.

The Aprilaire Model 700 is designed for larger homes, providing effective humidification for areas up to 4,200 square feet. In contrast, the DIGI MISTER is more flexible, accommodating spaces ranging from 1,000 to 3,500 square feet, making it suitable for smaller homes or offices. The choice between the two will largely depend on your specific space requirements and budget.

Humidification Performance

When it comes to humidification performance, the Aprilaire Model 700 stands out by releasing up to 18 gallons of water daily. This capability effectively combats health issues associated with dry air, such as sore throats and dry skin, especially during colder months. The built-in fan also pulls heated air directly from the furnace, enhancing the overall efficiency.

On the other hand, the DIGI MISTER employs a more adjustable approach, allowing users to change the number of fine mist nozzles from 1 to 5. This feature enables the humidifier to adapt to various room sizes and types of furnaces. While it does not specify a daily water output, the DIGI MISTER's atomized mist effectively evaporates into the air without wasting water, contributing to its efficiency.

Installation Process

The installation process varies significantly between the two units. The Aprilaire Model 700 requires a more traditional setup, involving ductwork and connections to your existing furnace system. While it may be straightforward for those familiar with HVAC systems, it might necessitate professional installation for optimal performance.

Conversely, the DIGI MISTER is designed for easy installation with a compact design that requires only a small cut-out for fitting. This unit does not require extensive ductwork or drainage, making it a more convenient choice for those who prefer a less invasive installation process. However, some HVAC expertise is still needed to ensure proper setup.

Maintenance Considerations

Maintenance is a crucial aspect of any humidifier, and both products offer different levels of convenience. The Aprilaire Model 700 requires annual water panel replacement to maintain its efficiency, but once set up, it operates automatically without the need for frequent intervention.

In comparison, the DIGI MISTER emphasizes convenience with its observation window, allowing users to visually check the water mist status. Its spray nozzles can be easily tested and cleaned, and the “swing-out” design facilitates effortless nozzle replacement. The inclusion of extra replacement nozzles adds to its long-term usability, but users must ensure adequate water pressure for optimal performance.

Digital Features

Digital control features set the DIGI MISTER apart, providing users with the ability to precisely adjust room humidity and duct air temperature. The unit also allows for humidity value calibration and offers flexibility in temperature units between °F and °C. This level of control can be a significant advantage for users who want to fine-tune their indoor environment.

The Aprilaire Model 700, while effective in its operation, does not highlight any advanced digital controls or settings. It focuses more on automatic functionality, which may appeal to those who prefer a straightforward, hands-off approach to humidification.

Energy Efficiency

Energy efficiency is an important consideration when selecting a humidifier. The Aprilaire Model 700 allows for lower heating bills by maintaining proper humidity levels, enabling families to turn down their furnaces during the winter. This can lead to significant energy savings over time, especially in larger homes.

The DIGI MISTER also claims to be energy-efficient, as it operates quietly without the need for high power fans or expensive steam canisters. Its design allows for atomized mist to evaporate fully into the air, reducing waste and saving money on water and electricity. However, precise energy savings may vary based on usage and the specific setup of your home.

Price Comparison

The price difference between the two units is substantial, with the Aprilaire Model 700 priced at C$598.00 and the DIGI MISTER available for C$302.61. This makes the DIGI MISTER a more accessible option for consumers on a budget, especially for those who may not require the extensive coverage provided by the Aprilaire Model 700.

While the Aprilaire’s higher price reflects its ability to humidify larger spaces and its robust performance, the DIGI MISTER offers a cost-effective solution with flexible capabilities that could suit a variety of smaller environments.

Which should you buy?

Choosing between the Aprilaire Model 700 and the DIGI MISTER ultimately depends on your specific needs and budget. If you have a larger home and prioritize powerful humidification performance, the Aprilaire Model 700 is likely the better choice despite its higher price. However, if you are looking for a more budget-friendly option that offers flexibility in installation and operation, the DIGI MISTER is an excellent alternative. Consider your space size, installation preferences, and maintenance willingness to make the best decision for your home.
