The Munchkin Portable Air Purifier, 4–Stage True HEPA Filtration System is one of the smallest models we tested, and it comes with a small price tag.
It was one of the better choices for a smaller, work–related space like an office or cubicle. You’ll need to plan on charging the device for about three hours for it to run for ten hours.
This purifier is compatible with all types of international voltages and can be used with the AC or DC adapter. The compact purifier includes a carrying handle and strap, making it easy to take on the go.
