"With the introduction of the whole-home humidifier in 1954, Aprilaire transformed the HVAC industry by opening the gateway for a whole new category of products for contractors to offer homeowners," said Bruce Darkow, product manager for Aprilaire.
"As far as we can tell, the Model 100 was one of the first indoor air quality [IAQ] accessories available for installation on heating and cooling systems."
Originally designed to compete with plate-type humidifiers, the Aprilaire Model 100 whole-house humidifier incorporated the same basic physics still used in several models of Aprilaire humidifiers today.
This year the company reached another milestone with the introduction of its whole-house dehumidifier at the 2004 Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo) in Anaheim, Calif.
A Little History
"The model numbers were then changed from 550A and 560A, to 558 and 568. The Model 600 replaces models 560, 560A, and 568." The Model 558 has been eliminated. The Model 550 is still part of the Aprilaire lineup.
Aprilaire is owned by Research Products Corp. Aprilaire Intelligent Solutions for Indoor Environments is an integrated group of air quality products designed for use with residential and light commercial heating-cooling systems. The humidifier anniversary celebration will continue throughout this year.
