I recently learned about the poor effects that non-evaporative humidifiers can have in air quality. I did a fair amount of research, and found this humidifier to replace the one in our bedroom. It gets painfully dry in Colorado, but with this humidifier both my husband and I have woken up feeling like there’s plenty of good moisture in the air. It’s also super quiet and has a dimmer for the power light, which makes it perfect for use in our bedroom.
