Review on RIYONG Portable Purifier Air Cleaner Rechargeable by Danielle Williams

I bought this product (cute purple design) and tested it. It's a good size, like a soda can. Only setup is to use the filter and optionally the clip. Firstly, charge it fully, then secondly, to turn it on, PRESS (don't press lol wrongly) the button 3 or more times depending on your strength to turn it on or off. Just practice. The claimed battery lasts up to 6 hours, but you can use the charger if you need more time. You'll see a color change and hear a light tone letting you know if it's on. I've used it in the bedroom and it seems quiet enough not to bother me. Maybe it's good to take it with you for future trips and put it in a hotel or rent a car.
