Take the office, as an example. A person's cubicle does not necessarily offer enough space for a standard humidifier, not to mention such public areas are often incredibly dry. The USB Doughnut Humidifier sits easily on a person's desk to ensure direct moisture contact without taking up too much space. To work, the USB Doughnut Humidifier simply needs to be plugged into a computer port and then placed into any glass or cup of water. Thus it requires [no separate water tank](https://www.trendhunter.com/trends/evaporative-humidifier). It is available in three colors (white, pink and blue) and also boasts a timer feature so that it isn't left running unattended. ## Trend Insights (Trend Hunter) - Score: 3.0/10 - Popularity: 40% | Activity: 43% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Art & Design](https://www.trendhunter.com/artdesign) > [Design](https://www.trendhunter.com/design) ## Key Themes ### Key Themes Behind This Trend - **Miniature Air Purifiers:** Disruptive innovation opportunity: Develop smaller and portable air purifiers for use in confined spaces like cubicles and offices. ### Where This Applies - **Home Appliances:** Disruptive innovation opportunity: Design compact home appliances that cater to small spaces like USB-powered air purifiers. - **Office Supplies:** Disruptive innovation opportunity: Create innovative office supplies such as compact USB-powered humidifiers for individual workstations. ## Related on Trend Hunter - [Car-Friendly Ultrasonic Humidifiers](https://www.trendhunter.com/trends/fire-diffuser-portable-humidifier.md) - [Unique Wireless Humidifiers](https://www.trendhunter.com/trends/kawaii-pet-tv-humidifier.md) - [Animal-Inspired Humidifiers](https://www.trendhunter.com/trends/kawaii-animal-humidifier.md) - [Novelty Noodle Cup Humidifiers](https://www.trendhunter.com/trends/novelty-humidifiers.md) - [Plant-Powered Humidifiers](https://www.trendhunter.com/trends/moss-humidifier.md) - [Flower-Filled Humidifiers](https://www.trendhunter.com/trends/aromatherapy-humidifier.md) - [Humidifying Stoneware Sculptures](https://www.trendhunter.com/trends/kumo-humidifier.md) - [Slender Two-in-One Air Modifiers](https://www.trendhunter.com/trends/humidifier-and-air-purifier.md) - [Portable Skincare Humidifiers](https://www.trendhunter.com/trends/dr-idriss-x-canopy-portable-humidifier.md)
