It won’t be long until winter air drying out your skin and attacking your sinuses, but Amazon’s helping you prepare by marking down a bunch of popular compact humidifiers in today’s Gold Box.

Standard desktop humidifiers range from $25-$40 depending on the size, or you can opt for a hotel-friendly travel humidifier (which uses a standard plastic water bottle as its reservoir) for $19.

These are some of the most popular humidifiers on Amazon, and one boasts over 7,000 reviews. Just note that these prices are only available today, or until sold out.
