Note: The Aprilaire 5558 is a wall mounted humidistat kit for this model. It is sold separately.

The Aprilaire 866 is a whole house humidifier with modulating output and a fan pack. This modulating capability allows the unit to meet a tighter relative humidity control for a much more comfortable environment. This model is capable of humidification of up to 6,200 feet and has a maximum steam capacity of 34.6 gallons per day.

This Aprilaire humidifier provides humidity in the form of steam to conditioned space through the included fan pack. This fan pack includes a wall mounted discharge grill with a fan blower assembly and stainless steel dispersion chamber. This provides ductless humidification throughout the home.

This model generates steam by energizing electrodes that connect to water in a disposable canister. To modulate this steam output, a modulating control must be used. Proper water level in the canister is maintained through cooperating drain and fill valves. Adding humidity through steam is an efficient and effective way to solve dry air issues in the home. Air with improper humidity can damage respiratory health as well as the home's paint, furniture and electronics.

A ductless installation allows for whole house humidification in scenarios where intensive ductwork is not possible or preferable or when the ducts are not accessible. In addition, maintenance is also easy with no cleaning or scrubbing! All that is required is for the canister to be removed and replaced. Plus, water filtration is never required for the operation of this digital humidifier.
