The AirTamer A320 Personal Air Purifier is lightweight and compact, making it easy to carry around in a purse or backpack. It looks like a sleek black USB flash drive, which is great for those who don’t want a machine-shaped personal air purifier cluttering up their desk.
When we tested the A320, it was clear that this personal air purifier can handle any situation. The purifier can be worn around your neck or attached to your bag using the included lanyard. It can also be placed on a flat surface and used as an ionic purifier.
The A320 was the only purifier that could be used in classrooms with high levels of known allergens (such as dust mites) and not cause an allergic reaction in children. On top of that, it’s one of the most powerful air purifiers we tested, producing nearly double the negative ions of our top pick.
Unfortunately, the A320 didn’t do well in our ease-of-use tests. While its charging port is located on the top of the device, you still need to flip it over to plug it in, which may be difficult if you’re wearing it around your neck. Also, while the device does tell you when it’s fully charged, there’s no indication of how much battery life remains. This means you won’t know if you should charge it again before heading out for the day or if you have enough juice to last through your commute home.
