Best Evaporative Humidifier

Stadler Form Oskar Big Humidifier

A smooth block of slate-colored ABS plastic seated on a curved metal stand, this handsome evaporative humidifier uses two large fans and a 1.5-gallon water tank to disperse moisture. Although large, the 18.5-inch-wide unit emitted only an easily ignorable low hum – a huge improvement over others of this type. Cleaning is as simple as replacing the filter every three months. While it doesn't have an LCD display, blinking lights indicate settings, water levels, and when to change the filter. And with a coverage area of up to 650 square feet, it filled a bedroom and living room with plenty of vapor. [$280; stadlerformusa.com]
