All About the Aprilaire Humidifier Model 800

Posted: 2019-06-18

There are items in your home that can cause it to attract dry air like wood floors, woodwork, furniture, and musical instruments. Due to excessive air conditioning in the summer, the air tends to become dry, which can trigger respiratory and skin problems. Many people suffer from a sore throat, dry nasal passages as well as itchiness and dryness of the skin because of exposure to dry, conditioned air.

Consulting your preferred HVAC company in White Bear Lake MN like Four Seasons Air Specialists can help you find solutions to your dry air problems.


Humidifiers are compact devices that add moisture to the air, commonly used to fight off dry, arid air in homes. These systems have been proven to benefit people with respiratory illnesses and dry skin.

A humidifier controls the amount of humidity in the air and uses a large reservoir of water attached to its base. The air passes through a filter and evaporates some of the water. This evaporated water moistens the air.

Features of the Aprilaire Model 800 Humidifier

The Aprilaire Model 800 Humidifier is a steam humidifier designed for home applications where evaporative units are less practical. It uses electrode technology and is simple to install, operate, and maintain. 

With electrode technology, electrical current flows between submerged electrodes, the resistance of water to the electric current heats the water.  The submerged electrodes are found in a replaceable canister. 

At the end of a humidifier season, the canister – including the electrodes, is replaced. No cleaning, no scrubbing, simply replace the canister and you’re ready for the next humidifier season. Electrode technology requires impurities in the water to promote the transfer of electricity.  For this reason, water filtration is not required with electrode technology, minimizing the complexity of the installation and on-going operating costs. 

The Aprilaire Model 800 Humidifier is a whole-home solution that helps you achieve total comfort through humidity control. As a steam model, the 865 complements non-forced air heating sources and other specialty heating systems. It is installed by a local HVAC professional.
