What customers say
Customers highly regard the Aprilaire Model 700 for its premium performance in whole-house humidification. The fan powered design reliably delivers consistent, comfortable humidity throughout large homes, even during severe winters. Users especially value the digital humidistat for offering precise, automatic control, leading to noticeable improvements in comfort and reduced static electricity. While the unit is considered robust and built to last, justifying its cost, installation complexity is a frequent concern.

Know before you buy
The Model 700 is designed to handle homes up to 4,200 square feet. It provides an output of 18 gallons of moisture per day, making it suitable for most large residential spaces.
Not necessarily. The unit features an intelligent dual-sensor system that automatically monitors indoor and outdoor conditions to maintain your preferred humidity level between 40% and 60%.
Unlike passive humidifiers, the integrated fan actively pulls air through the unit's water-soaked wick filter. This ensures that moisture is distributed evenly and efficiently throughout your entire home.
Like most evaporative humidifiers, you will need to replace the wick filter periodically to ensure optimal performance and air quality. The frequency of replacement depends on your local water hardness and usage levels.
The Aprilaire Model 700 is a whole-house unit designed to be integrated into your home's HVAC system. It is not a portable, floor-standing device and typically requires professional installation to connect to your ductwork and water supply.
