The USB Drive That Cured Asthma

The full title of this item is “USB ionic Oxygen Bar Freshener Air Purifier ionizer For Laptop & With a Nice Gift.”

Does it actually do anything? If the graphic of a kitchen, a family, a woman with a dog, and some other tiny things didn’t tip you off: no. You can’t “purify” air with “negative ions.” But that didn’t stop multiple reviewers from claiming it does, including one poor soul who claimed that this USB stick cured his asthma.
