Dimension comparison
Overview of the Products
When comparing humidifiers, two options stand out: the Aprilaire Model 700 Automatic Whole House Power Furnace Humidifier and the Large Whole House Humidifier - 5.5 Gal Cool Mist. The Aprilaire Model 700 is priced at C$598.00 and is designed for spaces up to 4,200 square feet, while the Large Whole House Humidifier is more budget-friendly at C$395.10 and caters to areas up to 3,229 square feet. Both products aim to improve indoor air quality, but they differ significantly in features and capabilities.
Design and Build Quality
The Aprilaire Model 700 boasts a built-in fan that pulls heated air directly from the furnace, ensuring effective humidification throughout the home. It is designed for whole-house use, making it suitable for larger spaces up to 4,200 square feet. In contrast, the Large Whole House Humidifier features a top-fill design with a 21L (5.5-gallon) water tank, allowing it to operate continuously for 12-20 hours based on the selected mode. This design caters to a wide range of environments, from living rooms to offices, and is portable thanks to built-in wheels.
Humidification Performance
The Aprilaire Model 700 can release up to 18 gallons of water per day, providing substantial humidity even in larger spaces. It effectively combats health issues related to dry air, such as dry skin and respiratory problems. The Large Whole House Humidifier, while it has a lower maximum coverage area, provides personalized humidity control with three mist settings (low, medium, and high), allowing users to adjust the humidity levels from 45% to 90%. While both products are effective, the Aprilaire Model 700 has a higher output capacity, making it a stronger contender for larger homes.
Ease of Use and Maintenance
Both humidifiers are designed with user convenience in mind. The Aprilaire Model 700 requires minimal maintenance with annual water panel replacement, and there’s no need for manual water filling, which simplifies operation during the winter months. The Large Whole House Humidifier features a top-filling system that eliminates the need to open the lid for refills, making it user-friendly. Additionally, it comes equipped with a remote control, a timer function, and an automatic shut-off feature for low water levels, enhancing its ease of use.
Health Benefits
Both humidifiers provide essential health benefits by improving indoor air quality. The Aprilaire Model 700 specifically targets health issues related to dry air, helping to alleviate symptoms like sore throats and cold or flu symptoms. It contributes to overall comfort, allowing families to lower their heating bills in winter by maintaining proper humidity levels. The Large Whole House Humidifier also promotes health by sanitizing the water with a UV lamp before misting, ensuring that the output is clean and safe. This feature is particularly beneficial for maintaining a healthy living environment.
Features and Technology
The Aprilaire Model 700 includes features that enhance its functionality, such as a built-in fan and the ability to cover larger areas effectively. However, it lacks some of the advanced controls found in the Large Whole House Humidifier, which offers three mist settings and additional customization options with extension tubes and nozzles. The Large Whole House Humidifier also operates at a near-silent level, making it suitable for use in bedrooms or offices without causing disturbances.
Pricing and Value
The price difference between the two products is significant, with the Aprilaire Model 700 priced at C$598.00, whereas the Large Whole House Humidifier is available for C$395.10. While the Aprilaire Model 700 provides higher performance and coverage, the Large Whole House Humidifier offers excellent value for those seeking effective humidification at a lower price point. The decision may ultimately come down to the specific needs of the user, such as space size and budget.
Which should you buy?
Choosing between the Aprilaire Model 700 and the Large Whole House Humidifier depends on your specific needs and budget. If you require a higher capacity humidifier for a larger home and are willing to invest more, the Aprilaire Model 700 is an excellent choice with its robust features and health benefits. However, if you are looking for an affordable option that still delivers effective humidification for moderately sized spaces, the Large Whole House Humidifier is a commendable choice with its user-friendly design and additional features. Ultimately, both products serve to enhance indoor comfort and health, making them valuable additions to any home.
