This humidifier uses nano-silver technology to keep itself clean.
This pretty little humidifier from Gaiam not only spares you the evil winter woes of dry nasal passages and itchy skin, it does one better — no cleaning. Instead of clumsy filters or wicks, antimicrobial nanosilver technology prevents mold growth, so the warm or cool vaporized water is 99.9 percent germ-free. Light sleepers take note: The“ultrasonic” hum is nearly silent. $169 at www.gaiam.com
