An Aprilaire Whole-House Humidifier is installed directly to your central new or existing heating and cooling system. Humidity is introduced into your home’s air in the form of water vapor, which prevents minerals from entering the air in your home and potentially into your lungs. Water is supplied to the distribution tray, allowing it to flow evenly across the Aprilaire Water Panel®. The resulting humidified air is then distributed via your heating and cooling system ductwork throughout your home.

Aprilaire humidifiers help by ensuring that your entire home has just the right amount of moisture for the ultimate in protection and comfort. Whole-house humidifiers help prevent premature aging of your home's structure, provide optimum comfort and can protect respiratory systems against viruses and bacteria.

Core Benefits. Every Aprilaire® product provides these important key benefits for your family and home.

Health
An Aprilaire Whole-House Humidifier can reduce the chance of upper respiratory problems. “Humidity reduces the incidence of respiratory infections and speeds recovery from the common cold.”—William J. Hitschler, MD, Archives of Otolaryngology (study of diseases of the ears, nose, sinuses, larynx, mouth, and throat).

Comfort
When the air in your home becomes too dry, your body is robbed of precious moisture, leaving you and your family with dry, itchy skin, and dry nose and throat symptoms. An Aprilaire Whole-House Humidifier can help alleviate all of these uncomfortable symptoms and more.

Protection
Dry air pulls moisture from walls and hardwood floors which leads to damaging, unsightly cracks. Valuable furniture, artwork and electronics are also subject to the adverse effects of dry air. An Aprilaire Whole-House Humidifier can help protect your home and its contents by supplying the correct amount of moisture to your home’s air.

Energy Savings
Most homeowners turn up the thermostat because they feel cold. An Aprilaire Whole-House Humidifier allows you to feel warmer at lower thermostat settings, saving up to 4% on your heating bill for every degree you lower your thermostat, according to the EPA.
