RH2 Series
The Most Accurate and Efficient Home Humidifier Available

Nortec, a world leader in commercial humidification, has designed a sleek and easy to maintain residential humidifier.

The RH-Series humidifier features the same state-of-the-art electronic technology as our commercial units, delivering accurate and dependable humidification to your home.

Comfort and Health

Studies show correct interior humidity levels minimize the spread of bacteria and viruses avoiding the problems associated with dry throats and nasal passages during the winter months while also keeping your skin supple.

Nortec RH-Series electrode steam humidifiers remove calcium and minerals from the water used so only clean, pure steam is added to indoor air, making the air in your home healthier to breathe.

Protect Valuable Furnishings, Instruments and Art

Wood and upholstered furniture, drapes, carpets and other fabrics around your home will all deteriorate more rapidly if they get too dry or too wet. They need correct humidity to maintain their shape and strength.

The same goes for fine art, antiques and expensive musical instruments, especially pianos, violins and related strings and woodwinds.

Reduce Static Electricity

Prevent those annoying static electricity shocks in the winter time by keeping your house humidified using the Nortec RH-Series.

Two models are available to cover all residential application: the RH-Series Space for in-space humidification and the RH-Series Duct for humidification
through the duct system.


All scale and mineral sediment is deposited into the cylinders which are easily changed and discarded. Cylinder replacement requires no special tools and can be done in a few minutes. A light on the unit indicates when the cylinder needs replacement.


Installation requires only a potable water supply, water drainage and 110-240V power. Units are wall mounted for direct room or duct steam distribution.
