Mistorb™ Mini USB Air Humidifier

The Mistorb™ Mini USB Air Humidifier is a compact desktop humidifier built for home use in spaces of about 10-20 square meters. It runs off a USB power supply and holds up to 0.5 liters of water, releasing mist through a single outlet for light, everyday humidification.

Operation is mechanical, so there are no digital controls to manage — just fill the tank and switch it on. A built-in timer lets it run for 2-8 hours before shutting off, and the unit stays quiet at under 36db, making it suited to a desk or nightstand. Note that it does not include water-shortage or power-outage shutoff protection, so keep an eye on the tank level during use.

Why it works

• A round, injection-molded plastic shell keeps the design compact for tabletop or desktop placement.
• The 2-8 hour timer function gives you flexibility for short bursts or longer sessions without staying by the unit.
• Noise stays below 36db, so it can run near you without being disruptive.
