If your bedroom feels dry at night or you wake up with a scratchy throat, a small humidifier can make a big difference. The Everlasting Comfort 2.5L top-fill cool mist humidifier is currently on Black Friday sale for $28.79, down from $47.99, which is a 40% discount. It’s designed for bedrooms and nurseries, with quiet operation, built-in night lights, and even an essential oil diffuser function.

This model is built around convenience and low-fuss daily use. The 2.5L tank is sized for up to 24 hours of runtime, so you can run it overnight without constantly refilling. Because it’s a top-fill design, you just lift the lid and pour water in from above, which is much easier to fill and clean than traditional bottom-fill tanks.

Key features include:

The combination of humidifier and diffuser makes it a dual-purpose bedside device rather than just another appliance taking up space.

What stands out here is how many small quality-of-life features are packed into a budget-friendly unit. The top-fill design is genuinely helpful if you’ve ever wrestled with flipping and carrying a full tank over a sink. It also makes it easier to keep the tank clean, which matters for air quality over time.

The quiet ultrasonic operation and 24-hour runtime are well-suited for bedrooms, especially if you like to set it in the evening and forget about it until morning. The night light and timer controls add flexibility depending on how you like to sleep or whether you’re using it in a kid’s room or nursery.

The built-in essential oil tray is not a must-have for everyone, but it’s a nice bonus if you already use oils for light scent or relaxation. At the current 40% off price, you’re getting more than just basic humidity control in a compact, easy-to-use package.

If you’ve been meaning to add a bedroom humidifier before winter air really dries things out, this is a solid time to do it. At $28.79, down from $47.99, this top-fill cool mist model offers a full night of runtime, quiet operation, simple controls, and a built-in diffuser, all at a very approachable Black Friday price.
