Honeywell Drum Humidifiers
Honeywell drum humidifiers use a foam drum which rotates through a water filled basin. The foam absorbs water from the basin, and the absorbed water is evaporated as the drum spins. This type of humidifier is usually set up as a bypass system wherein the hot air is taken from the plenum, blown through the drum humidifier, and the humidified air is put back into the cold air return to cycle through the furnace again.
Drum humidifiers are often subject to quite a bit of maintenance as minerals will quickly build up on the foam drum. This quickly reduces the efficiency of the humidifier and will eventually cause the drum to need to be replaced. The only drum humidifier which has solved this issue is the Desert Spring Humidifier, as they use a patented disc assembly instead of a foam drum.
Honeywell Flow Through Humidifiers
Honeywell Flow through humidifiers operate by forcing a portion of hot air across a wetted humidifier pad. Flow through models of humidifiers are notorious for wasting water. In independent tests, the three leading flow through humidifiers on the market used between 5,000 and 8,000 gallons of water per year, whereas the Desert Spring Humidifier uses only 59 gallons and virtually all of that was put into the air as humidity.
Honeywell Steam Humidifiers
Honeywell steam humidifiers operate on the same pricipal as other steam humidifiers. They blow water vapor in the form of steam into your home. This type of humidifier will humidify your home even without your furnace operating. Unfortunately, as the water has not completely evaporated, it will often leave moisture in duct work, sometimes causing mold and bacteria growth.
