The H12-400HB/H12-300HB/H12-600HB evaporative humidifiers are designed for large spaces. Its 5.4-gallon reservoir and long run time mean fewer refills. It features four fan speeds, an adjustable humidistat, auto shutoff, refill indicator, and check filter indicator. It is available in three wood-tones, so the console blends seamlessly into any room. The H12-400HB uses one 1045 Super Wick (included) and one 1051 air filter (sold separately).
