Benefits of Evaporative Humidification

  • Protects Fine Furniture and Wood Floors
  • Relieves Dry Skin & Scratchy Throats
  • Reduces Heating Costs

How It Works

The Aprilaire 700 has been designed to integrate with the HVAC blower. It adds moisture to the air by taking hot air from the blower to evaporate water and distribute it around your home. If your home humidty drops below the ideal level whilst the HVAC blower is running, water is added to a distribution tray on top of the humidifier unit. The tray has numerous outlets along it’s width designed to allow water to flow evenly across the unit.

Gravity is utilised to allow the water from the outlets to run through the water panel evaporator. Warm and dry air from the HVAC blower is pushed through the water panel causing the water to evaporate naturally. Finally the built iin fan pulls the moisture from the water panel and out to humidify your home.

It's All About Balance

The Aprilaire 700 can easily restore the moisture balance
in your home with the ability to cover an area of 4,200 sq. ft.

Spent many hours researching how to install a whole house humidifier and this one was recommended many times. When our furnace got serviced this fall the technician also recommended we get a humidifier and when I asked him which model this is the one he recommended. It’s really hard to find anyone selling this unit because the manufacturer doesn’t want just anyone to install it, they recommend a technician so I was pretty happy when I found it on Amazon.

I had been researching whole house humidifiers for some time and finally decided on this Aprilaire Model 700 Automatic Whole-house Powered Humidifier with Digital Control from talking to local HVAC installers and reviews I located online. I checked around and the lowest I could find someone to install it for me was $350, so I decided to take the plunge and do it myself.

We are so happy with this humidifier! We live in an area where the air gets very dry and it was making us miserable. We had to play with the settings to get just the right level but we have been very happy with this unit and highly recommend it to everyone!
