11+ Bottle Humidifier Review

Updated on

March 30, 2021

A thoughtfully designed and visually appealing humidifier is surprisingly hard to find. I ended up purchasing a white Middle Colors humidifier for my bedroom, but I wanted something smaller and more suitable for my desk at work or home.

After discovering the Bottle Humidifier designed by Yeongkyu Yoo over at 11+, I was immediately sold. Here is my review of it after regular use over the last year.

Note: This review doesn’t contain any images of the packaging, but I would recommend you check them out at Yeongkyu’s Behance Project.

The first thing I noticed after taking it out of the packaging was the contrast between the white matte surface and the bright orange power cable.

There are two simple controls on the humidifier marked with a + and -. Pressing the + once will start the device regularly, and pressing it a second time will start it in intermittent mode — perfect for smaller areas.

When the unit is running, a soft blinking light appears above the controls. These are my favorite type of indicators, as they only need to be visible when the device is on.

Another one of my favorite things about the design is the pottery like qualities of the matte material, combined with the sharp edges near the top.

It reminds me a little of the handmade vases from Tortus Copenhagen. It sits tall just shy of 8 inches.

It’s been designed with an ultrasonic nebulizer, which is energy efficient, and automatically turns off when water is depleted.

The humidifier is made of PC-ABS thermoplastic which is a durable, heat resistant material.

The humidifier has a capacity of 440ml (15oz.) and will automatically turn off when depleted, or after 5 hours of use.


It’s filled by merely lifting the humidifier off its base.


The filters are replaceable, and each unit comes with an extra.

The USB power cable is about 55 inches long, and I’ve typically been using it plugged into my laptop, or in an outlet with an old iPhone charger.

Final thoughts

The +11 Bottle Humidifier is one of my favorite items in my apartment from a design perspective, and will always have a spot on my desk, even when it’s not in use. While the output isn’t enough for a medium to large size room, it’s excellent in a small area while you’re working.

It’s the perfect example of a regular, everyday item that can instantly transform into something special with some thoughtful design. That mentality is apparent within the other products at 11+, and I can’t wait to get my hands on more.
