  • Performs quietly and with simple maintenance. You only need to replace the canister.

  • Uses cold water, which may be hard, soft or softened.

When you use the Aprilaire Model 800 Humidifier, you eliminate the unhealthy and damaging effects of overly dry air on your family and home.

Aprilaire De-Humidifier

Daily activities, such as cooking, cleaning and showering can add as much as 25 pounds of moisture to your home.

Your air conditioner is designed to control temperature, not humidity. You need humidity control to maintain comfortable, healthy conditions in your home.

A whole-home dehumidifier is installed as part of your home’s heating and cooling system. It works in conjunction with your air conditioner, or independently as needed, to remove the ideal amount of moisture to solve the above problems. But not so much that your home becomes too dry.

This is done throughout your entire home, using a single, out-of-the-way source—unlike a portable dehumidifier.


Other advantages of a whole-home dehumidifier include:

  • Automatic humidity sensing: allows for better monitoring and control of humidity
  • Convenient, quiet operation: away from your living space
  • Low maintenance dehumidifier: simple annual filter cleaning
  • Fresh air ventilation: automatically removes or dilutes polluted air.
