I wake up and it’s freezing, but then I’m sweating through my hoodie by the time the afternoon rolls around. That’s where a space heater comes in handy. Right now, Amazon has Dreo space heaters, all of which are editor-approved, on sale before the real cold rolls in. This quiet (28 dB) humidifier runs up to 36 hours on one fill and doubles as a nightlight. It’s a great way to relieve dry indoor air as heating season ramps up, keeping your skin and sinuses happier.
