Honeywell Honeywell Cool Moisture Humidifier - HCM-890B
The Honeywell HCM-890B is a very basic and affordable humidifier, being available for as little as $15 at some online retailers. The HCM-890B is very compact and easy to live with, offering both high and low settings, an antimicrobial filter, and enough performance to effectively add moisture to a small room such as a bedroom.
Concessions for affordability are seen in the lack of an automatic shutoff feature, as well as comparatively louder operation on the high setting; on low, noise fades into the background as white noise. However, despite being a bit loud, the HCM-890B works well, doesn't leak, and is a very affordable and easy-to-use option.
