Useful for alerting you to when it’s time to either empty or replace the water reservoir in a bypass/drum humidifier.

The humidifier will turn off should the water reservoir ever drop below the heating element.

Some units allow you to set your desired humidity level and the humidifier will automatically maintain that level.

As water evaporates from humidifier reservoirs, it replaced by fresh water. A float valve prevents the unit from overflowing by shutting off the water at a desired level.

Assists in easy installation onto existing ductwork.

Some whole-home humidifiers are enclosed in corrosion-resistant housing to protect the longevity of the unit.

Reversible side panels allow installers to place the unit on either the left or the right of ductwork, so that it’s in the best possible location.
