Aprilaire Model 700 High-Capacity Whole House Humidifiers

Product Overview

Protect yourself and your home from the negative effects of chronically dry air when you use the Aprilaire Model 700/700M Whole House Humidifier. This powered flow-through humidifier works with your existing heating and cooling system to deliver properly humidified air throughout all the rooms of your home. The Model 700 functions as an evaporative humidifier, distributing up to 18 gallons of moisture per day. This is enough to humidify tightly sealed homes up to 4,200 square feet, average sealed homes up to 2,100 square feet, and loosely sealed homes up to 1,050 square feet.

Why Use A Whole House Humidifier?

Low indoor humidity during the winter months – and year-round if you live in certain climates – often spells trouble for you and your home. Dry air symptoms like itchy dry skin, parched lips, respiratory irritation, and nasal allergies can all be triggered by low humidity. When it comes to your home, chronically dry air undermines your home’s infrastructure, causing walls, woodwork, and hardwood floors to crack. Even your electronics can fall victim to harsh static electricity. To protect yourself, your belongings, and your home, opt for a ducted whole house humidifier. 

Powered Model, Features a Built-In Fan

This whole-house humidifier is a powered flow-through model that is among the highest-capacity in-duct humidifiers sold. It’s designed to be installed on the hot air supply plenum of your HVAC system. The built-in fan – not your HVAC blower – draws dry air into the humidifier from your furnace. This model is also equipped with a built-in drain to flush mineral build-up from the machine. As a result, water does not accumulate inside the unit.

How It Operates

When connected to your HVAC system, the Aprilaire Model 700/700M Flow-Through Whole House Humidifier humidifies your home using a natural evaporation process.

• Step 1: When the humidifier controller triggers a need for more humidity, water automatically flows from the connected water line into a distribution tray located at the top of the humidifier. Water is distributed evenly across the width of this tray and directed to flow over Aprilaire’s patented Water Panel evaporator into the heart of the humidifier.
• Step 2: Moisture from the distribution tray is then evaporated into the incoming dry air, creating comfortably humidified air. Humidified air is then distributed throughout your home through your HVAC system’s return duct.
