If dry winter air is wreaking havoc on your sinuses, you can fight back with this Eufy (Anker’s home division) humidifier. The Humos Air 1.0 can run 20 hours with its one gallon tank, and can humidify a room with hot or cool mist, depending on the season. $36 is the best price we’ve ever seen on this model, and about $6 less than usual.
