Review on Munchkin Portable Air Purifier: Advanced 4-Stage True HEPA Filtration System, Eliminates 99.7% of Micro-Pollutants on the Go! by Kim Mouton

I love this brand and spend a lot of money on it but after receiving this product I found it a small, noisy and unsafe toy. When I press the power button on the back, it doesn't turn off, after so many tries, it seems the button is dead, and the small fan makes a huge noise, and with less wind volume, it gets better. have no effect on the air. Quality, also there is a small hepa filter as it can capture and trap dust and pollen. When I have it on hand, the bottom cover easily falls off along with the filter, and the fan still works, how can a well-known brand develop such a product. I won't be using this in any of my kids' environments because it's too loud. And since it's not worth the money, I'm sending it back.
