The air inside your home is drier than you think. Heating your home dries out the air. The resulting dry air absorbs moisture from you and everything inside your home. Even newer, tighter built homes will succumb to the negative effects of air that is too dry.

Humidification, the process of adding moisture to the air, is one of the most important aspects of total indoor comfort, yet it’s one of the least understood. One reason is that humidity is an intangible. It can’t be seen, touched, or smelled. It has no color, no sound. However, its presence, when controlled properly, offers many proven benefits.


Heating your indoor air dries out your skin. This not only makes you feel itchy but can also make you feel chilly. This cold effect is not the only discomfort caused by too dry air. Annoying static electricity is another indication of low humidity levels. Proper relative humidity (RH) will reduce this discomfort.

Aprilaire whole-home humidifiers provide maximum comfort throughout your entire home—every hour, every day, all season long, without the mess and inconvenience of portables.


Air that is too dry can make you more susceptible to catching cold or flu viruses. How? Dry air dries out your nasal membranes and makes the lining of your nose more susceptible to bleeding and infections. Also, low levels of humidity have been linked to the speedier progression and transmission of viruses in the air.

Proper humidity is a key factor to staying healthy in winter. By keeping your sinuses and airways moist, you reduce the potential for bacteria and viruses to enter your body. Aprilaire humidifiers are proven most effective at providing optimum levels of humidity.


The addition or reduction of moisture drastically affects the qualities, dimensions, and weights of many materials. For example, wood, leather, paper, and cloth all contain water. Paper, plastic, cloth, fibers, glue, skin and practically everything else in the home shrink as they lose water, and swell as they take on water. If the water loss is rapid, warping and cracking can take place. As the RH changes, the condition and dimensions of the materials change, as constantly as the weather. This is why humidity must be added and controlled. Your home and its furnishings make up what is likely your largest investment. By providing constant humidity control, Aprilaire humidifiers help to keep them in good condition, maintaining their value and extending their life.


An Aprilaire whole-home humidifier also allows you to feel warmer at lower thermostat settings. The U.S. Environmental Protection Agency reports that you can save up to 4% on your heating bill for every degree you lower your thermostat.

The Lynch Company, Inc. Aprilaire whole-home steam humidifiers have many distinct advantages over room-sized portable units. One is that they can either be installed as part of your forced-air heating and cooling system or independently, without the need for ductwork. That means any home can enjoy care-free comfort. They deliver perfect humidification throughout your entire home without having multiple noisy, unsightly and difficult-to-maintain portable units. They are low maintenance and can introduce as much as 30 gallons of water per day into the home to meet a wide variety of needs. The 800 unit does not need the heat to be running to humidify so you can maintain your desired humidity level without constantly running the heat.

The Lynch Company, Inc. Aprilaire evaporative humidifiers are used for smaller homes or as a lower cost alternative to steam humidification. They are easily installed, and require less electricity, however because they rely on evaporation to produce humidity they have a lower capacity for humidification than the steam system. This also means that these units only introduce humidity to the home when your heat is running, so if you turn your heat down or off at night you would not be humidifying the home until the heat is turned back on. This can lead to inconsistencies in the relative humidity inside the home.
