Why Aprilaire Whole-Home Humidifiers? Aprilaire Whole-House Humidifiers were introduced in 1954 as the first evaporative, flow-through design humidifiers. That’s right—we invented the very first, truly effective, whole-home humidifier. Since then, Aprilaire Humidifiers have been imitated—but never duplicated—and continue to lead the way in whole-house humidification systems. And only Aprilaire offers fully Automatic Digital Humidifier Control to monitor outdoor temperature and indoor humidity levels while providing convenient troubleshooting and maintenance reminders.     Heating your home causes the air to become dry. April air humidifiers help put the moisture back into the air. The dry air in your home is drying to your skin and hair. Very dry air can damage wood flooring and furniture as well. People with respiratory disorders, such as asthma, find dry air to be irritating to the condition. Installing april air humidifiers helps avoid these problems caused by dry air. Humidifiers do more than just add moisture to the air in your home. They can help cut the cost of heating your home. Humidified air feels warmer and your home will be more comfortable at a lower setting on the thermostat. This enables you to lower your thermostat and save money on high energy bills.
