Overview of the Products

When it comes to whole house humidifiers, the Aprilaire Model 400 and the AprilAire - Evaporative Humidifier Fan Powered 720 Meters stand out as popular choices. The Model 400 is priced at C$407.00, while the 720 Meters comes at a higher price of C$821.98. Both models are designed to enhance indoor air quality by maintaining optimal humidity levels, but they do so in different ways and capacities.

Humidification Capacity

The AprilAire - Evaporative Humidifier Fan Powered 720 Meters boasts a remarkable capacity of 21 gallons per day, making it ideal for larger homes. In contrast, the Aprilaire Model 400 offers a maximum capacity of 17 gallons per day, which is sufficient for homes up to 4,000 square feet. While both models are effective, the 720 Meters provides a quicker balance of moisture, which may be more beneficial for larger living spaces.

Water Efficiency

Water conservation is a crucial aspect of any humidifier. The Aprilaire Model 400 uses a unique process to evaporate 100% of the water flowing into the water panel, thus conserving water efficiently. However, the 720 Meters takes this a step further by reducing wastewater by 60% compared to previous models. Its innovative recirculation valve allows it to recycle water, delivering three times more water through the panel while minimising waste, which is particularly appealing for environmentally conscious consumers.

Installation and Maintenance

Both humidifiers offer ease of installation, but they cater to different preferences. The Aprilaire Model 400 is designed for straightforward setup and can operate effectively with minimal input. Meanwhile, the AprilAire - Evaporative Humidifier Fan Powered 720 Meters features a one-piece HydroCore water panel that simplifies maintenance and is made from recycled plastic, demonstrating an emphasis on sustainability. This model also allows for reversible fan configuration, making it versatile for various home layouts.

Control Features

Control mechanisms differ significantly between the two models. The Aprilaire Model 400 operates automatically through dual sensors that monitor both outdoor temperature and indoor humidity, providing a set-and-forget experience. In contrast, the AprilAire - Evaporative Humidifier Fan Powered 720 Meters comes with a manual control option, allowing users to monitor and adjust humidity levels more actively. This can be beneficial for those who prefer direct control over their indoor climate.

Health Benefits

Both humidifiers are designed with health benefits in mind, primarily targeting issues associated with dry air. The Aprilaire Model 400 helps alleviate symptoms related to dry skin, sore throats, and respiratory infections, maintaining optimal humidity levels of 35% to 45%. The 720 Meters also contributes to health by improving air quality and reducing the incidence of respiratory issues, with added efficiency in moisture distribution. While both models focus on health benefits, the 720 Meters offers a faster response in larger spaces.

Brand Reliability

Aprilaire has established itself as a leader in indoor air quality solutions since 1954. Both products are designed and assembled in the USA, ensuring a level of quality and reliability. The Aprilaire Model 400 is backed by the brand’s longstanding reputation as the inventor of whole home evaporative humidifiers. Similarly, the 720 Meters comes with a 5-year warranty, reflecting the company's commitment to customer satisfaction and product durability.

Price Comparison

When it comes to pricing, there is a considerable difference between the two models. The Aprilaire Model 400 is priced at C$407.00, making it an affordable option for homeowners seeking to improve their indoor air quality. On the other hand, the AprilAire - Evaporative Humidifier Fan Powered 720 Meters is priced at C$821.98, reflecting its advanced features and higher capacity. The choice between these two will largely depend on one’s budget and specific needs for humidification.

Which should you buy?

The decision between the Aprilaire Model 400 and the AprilAire - Evaporative Humidifier Fan Powered 720 Meters depends on your specific requirements. If you are looking for an economical option that provides reliable performance for mid-sized homes, the Model 400 is an excellent choice. However, if you require a more powerful humidifier that can handle larger spaces with advanced features like water recycling and manual control, the 720 Meters is worth the investment. Consider your home size, budget, and desired features to make the best choice for your indoor air quality needs.
