Quality air is one of the fundamentals of health and safety for your home and family. Many consumers don’t realize that indoor air can be more polluted than outdoor air – even in areas with heavy pollution! And dry air can be a hazard to your home and your health. Ensuring healthier, cleaner air in your home starts with a quality humidifier you can trust. We proudly recommend the Aprilaire Model 700 Humidifier, a best-selling whole-home humidifier suitable for medium to large homes.

The Aprilaire 700 Humidifier is a large-capacity unit that humidifies homes up to 4,200 square feet and delivers up to 18 gallons of water each day. An Aprilaire humidifier can help relieve and prevent issues caused by dry air in your home, and helps provide comfort and better indoor air quality no matter the season or weather outside. Home humidifiers are an important and essential aspect of your home’s longevity and your family’s comfort and health.

Benefits of the Aprilaire 700 Model Humidifier:

  • Large capacity – humidifies homes up to 4200 square feet 
  • Whole-home humidifier – no topping off small units in multiple rooms 
  • Truly automatic – you’ll never have to guess or wait until you notice dry air 
  • Simple installation – simply install into your supply duct or request a local HVAC professional 
  • Efficient and effective – uses the warm air from your furnace to produce humidity 
  • Trusted brand – Aprilaire humidifiers are a top brand in the industry

This unit features the new #60 humidistat that enables your system to be automatically controlled - taking the guesswork out of the equation! The #60 humidistat mounts directly to your return duct and will notify your humidifier when more humidity is needed to reach the desired set point. No more guessing or waiting until you realize the air is too dry! If you prefer manual operation to automatic, you can have the Aprilaire 700 installed in manual mode.

When it comes to the Aprilaire 700 installation, simply install into your supply duct or request installation from a local HVAC professional. Your Aprilaire humidifier comes with a built-in fan that pulls the warm air from your furnace and uses it to create humidity, making it more efficient and effective at humidifying your home than a bypass humidifier. The plenum (duct) opening measures 14 3/4" by 14 5/16".

The Aprilaire 700 Humidifier comes as a complete system and includes the following items with purchase:

  • #60 Automatic humidistat
  • #35 Aprilaire water panel
  • Outdoor temperature sensor
  • Saddle valve
  • 24V transformer
  • Owners manual

Add the new Aprilaire 700 Humidifier Annual Maintenance Kit to your order! This convenient kit gives you all the parts you need to maintain your Aprilaire humidifier each year and keep it running in like-new factory condition.

This whole home, fan-powered humidifier is a direct dimensional replacement for the Aprilaire 760 humidifier.

5 Year Manufacturer's Warranty.
