When speaking of higher anxiety level after wearing a mask over certain period not by training to do so, I don't think I am alone. It's not easy to cope with, at least in my case. And finally, this small device comes to rescue, what a relief!It's well designed with good production quality, easy to use and it's well thought of various applications by the built-in multiple fan speeds. After using it for a week, I can now say from experiences - it indeed improves the comfort level of wearing a mask for a substantial period.I would definitely recommend this for people who needs to wear a mask often, great product!

It is such a smart invention! Very easy to put on the mask and doesn’t feel uncomfortable while wearing the mask. It lowers the humidity and removes the breath smell. Also, it doesn’t need batteries and you just have to recharge. Definitely worth buying.

Good quality

Ordered this on recommendation from my brother that had nothing but good things to say about it. I was hoping to find a solution to minimize the stuffiness from the hot air trapped in n95/kn95 respirators. It sometimes feel like I need to breathe in deeper to get fresh air, most often on hot and humid days. I was a bit skeptical that such a small fan would make a difference but it does. The unit consists of two hinged halves and clips onto most respirators and surgical masks (as long as there is enough flat surface for it to clip onto). The fan is on the inside section and it is supposed to pull fresh filtered air through the mask material. I'm not sure how much air it actually pulls through the mask but at least it moves the air enough inside the mask to minimize the stuffiness. It has 4 speed levels with led lighting up briefly in different colors to tell you which setting you are on. Based on my own use, on the lowest setting it can last for at least 10 hours without charging. I usually use it on the lowest or second lowest setting and it is enough for me. I ordered 2 units and one was faulty. It sometimes randomly turned on and couldn't be switched off for awhile. The exchange process was painless and I didn't have any issues with the replacement unit. A bit pleasantly surprised the roduct is made in Taiwan, not China.

I have to commute to work by bus for ~ 50 mins a day. This fan keeps the moisture out of the mask with better air circulation. Makes me feel cool and easy to breathe.The product is well designed. It can be easily attached to any disposal mask. It’s light and the battery can be recharged with a USB Port. I suggest to mount the fan near the upper left of the mask edge. This way you can feel the air flowing out of the fan directly to your noise!
