This QuietCare model has a fan that blows out invisible, moisture-balanced air, and is 30 percent quieter than other models. It has manual controls for simple operation and 3 moisture control settings. The Protec cleaning cartridge helps reduce mineral build-up, while the antimicrobial-treated filter helps prevent the growth and migration of mold, fungus, algae and bacteria on the filter--both contributing to a fresher, cleaner mist and extend filter life.
The HCM-630 has a 1-1/4-gallon tank capacity, an adjustable humidistat that maintains desired comfort level, and an auto shut-off function that occurs when desired humidity level is reached or tank is empty. It measures 8 by 13-3/4 by 16 inches (WxHxD), is backed by a 5-year warranty, and uses HAC-504/HAC-504AW replacement filters.
