The purifier works better than I thought it would. I have a breathing problem so I bought this product. The air is so comfortably purified that it relaxes me. I can sleep peacefully when I fly. I highly recommend this product.


It's the perfect product to go out in this covid season. We admit it's even better than today's masks. I'm always skeptical of traveling in close-fitting comfort. But with the 4WDKING, it's a piece of cake. It fits perfectly on my arm, or even better on my bag.


This is the perfect mask right now. My grandfather recently received one. It's exactly what he needs. He looked like he was suffocating a lot in the regular mask. And the large size fits him perfectly.
