Brand new humidifier in the box. I did pull it out to plug in and make sure it worked. It works! This model is from 1993. It features 2-speed settings and a whisper-quiet mode for nighttime use. The unit provides natural, evaporative humidification, covering up to 800 square feet with a capacity to run for up to 28 hours without a refill. It is designed to trap minerals in the water, preventing white dust, and uses a wicking filter to moisturize the air. The humidifier is marketed as easy to fill and clean. Reach out with any questions!
