Overview of the Products

When it comes to whole house humidifiers, both the Aprilaire Model 700 Automatic and the Aprilaire 700M Whole-House Humidifier stand out for their performance and features. The Model 700 is currently priced at C$598.00, while the 700M is slightly more expensive at C$615.88. Both are designed to provide optimal humidity levels for homes up to 4,200 square feet, making them suitable for larger spaces.

Features and Benefits

The Aprilaire Model 700 Automatic boasts several features aimed at enhancing comfort and health in your home. It can release up to 18 gallons of water per day, effectively combating issues related to dry air, such as dry skin and sore throats. In contrast, the Aprilaire 700M offers a manual control system and an evaporation capacity of 0.75 gallons per hour, which is among the highest for similar products. Both units are fan-powered, ensuring efficient humidity distribution throughout your home.

Ease of Use

The Aprilaire Model 700 Automatic is designed for convenient operation, eliminating the need for manual water tank filling. Its built-in fan draws heated air directly from the furnace, making it a set-and-forget solution once installed. On the other hand, the 700M requires manual adjustment for humidity control, which some users may find less convenient. However, both models are straightforward in terms of maintenance, requiring only an annual water panel replacement to ensure optimal performance.

Health and Comfort Improvements

Both humidifiers aim to improve health and comfort by addressing issues related to dry air. The Aprilaire Model 700 Automatic claims to help with symptoms like cold and flu, which can be exacerbated by low humidity levels. The 700M also contributes positively to air quality but focuses more on its high evaporation capacity as a key selling point. While both products address similar health concerns, the Model 700's automatic features may provide an edge in convenience and effectiveness.

Price Comparison

Pricing is an important factor when choosing between these two models. The Aprilaire Model 700 is priced at C$598.00, making it the more affordable option of the two. The 700M, while slightly more expensive at C$615.88, offers a robust set of features that some users might find worth the additional cost. Both units are priced competitively within the market for whole house humidifiers, but the Model 700 offers a slight financial advantage.

Warranty and Support

Both products come with a manufacturer warranty, although specific details about the warranty period for the Model 700 are not expressly mentioned. The Aprilaire 700M comes with a 5-year manufacturer warranty, offering peace of mind for consumers. A strong warranty can be an important factor for buyers looking for long-term reliability and support, making the 700M a compelling choice for those who prioritize warranty coverage.

Installation Considerations

Installation is an essential aspect of any whole house humidifier. The Aprilaire Model 700 Automatic is designed to be integrated with a home’s existing furnace system, which may require professional installation if you're not experienced with HVAC systems. The 700M also requires similar installation considerations, but its manual controls could allow for simpler adjustments post-installation. Potential buyers should factor in installation costs and expertise when deciding.

Which should you buy?

Ultimately, the choice between the Aprilaire Model 700 Automatic and the Aprilaire 700M Whole-House Humidifier depends on your specific needs and preferences. If you value ease of use and automated features, the Model 700 offers significant benefits at a slightly lower price of C$598.00. However, if you prefer manual control and a solid warranty, the 700M at C$615.88 is a strong contender. Both units effectively humidify spaces up to 4,200 square feet, making either choice a reliable option for improving your home’s air quality.
