Small Desktop Portable Air Purifier for Office, Car, Travel, Small Room and Home, Removes Cigarette Smoke Pollen Dust Odor, Powered by USB No Adapter

This small desktop portable air purifier is a mixed bag with a few happy customers and a few disappointed customers. On the positive side, it seemed to work well for a few customers who used it in cubicles and felt that it improved the air quality. A customer who vapes put its air-cleaning capabilities to the test and was impressed with its effectiveness. It is also reasonably priced at $20. However, the majority of the negative feedback centered around how cheaply made this air purifier is with a loud whining noise after just a few uses, not being able to power on, and burning out after a few weeks. Additionally, some customers felt deceived by its light weight and flimsy appearance, stating that it is not effective for its intended purpose of clearing the air in a small office space. Overall, this product might be worth a try if you're looking for a low-cost air purifier to use in a car or small room, but keep in mind there is no option to replace the USB cable that comes attached to the machine and it may not last long.
