G·SENYE Face Mask Fan, Portable Mini Mask Cooling Fan with Clip Electric Mask Air Fans Wind Kiss Mask Filter Fan for Kids and Adults

The first thing I will say about this mask is that it works well with those surgical mask or thin mask material. It provides a good amount of air flow and it is not too noticeable when wearing it. The thicker mask unfortunately do not work too well with this. My thick cloth mask had a hard time getting proper air flow. I actually had more hot air as the warm of my breath was not clearing the mask. It also looked a bit awkward on the thicker mask. That being said, on my thin material and surgical mask, it provided a good breath of cooler air. It also kept my mask dry from sweat as well as provide a good way to vent my breath so my glasses don't fog up (I hate when that happens!!). It is not too noisy so you do not really notice it after awhile. You do at first. It last for several hours and just needs to be recharged for an hour or two. You do need to press and hold the power button to turn it on. I am not sure if this is just a prevention but it seems to only have one fan setting. You have to press it twice to turn it off. I thought maybe it was a different power setting but it does not get louder or change the air flow from what I can tell. The manual also does not say if it has more than one setting. The white is prone to yellowing from the time I used it. It yellowed a little bit with me watching in the sun with this on my mask. It does not hinder performance but is a cosmetic thing (no way to really prevent it). It is not too heavy so it secures to mask pretty well. When putting it on, make sure the fan is face OUT and not in or you just be pulling the warmth from your skin in. There is an led light indicator. One thing I did notice is that it does take a few seconds to really rev up and get cool air in. There is an LED light indictor to show charging and such. Charging does vary based on the medium you are using. It does come with a nice carrying bag and simple micro USB cable. The battery is small so it is a fast charge regardless. The micro USB is under the silicone cover which I thought was a button. It keeps water from getting into the charging port. I have not seen much issue with dust just yet on the fan so I am unsure if you will really need to clean it too often in the fan but the outside just wipe it down. Overall this is a good mask fan if you are using it on surgical or thin mask. Unfortunately with thick mask, it does not perform as well. It most likely because the thicker material retains heat longer. Regardless of that, it does do a good job in providing cooler air to thin/surgical ask as well as provide an opening for your warm breath to escape. This means NO MORE FOGGED UP GLASSES!! The only other issue is that it does yellow in the sun but again that is cosmetic. It last for quite sometimes and does not take long to charge.

Portable fan for your face mask I got this so I can put it on is my facemask while I’m at work because it gets very hot while I’m working with a face mask on this as well worth the money I’d love that is rechargeable this is a great price highly recommend it

They are very heavy, they don't push air out into the mask, very disappointing.

Nice quality and easy to use. Fully chargeable and powerful fan. Clips on side of mask and blows cool air into the mask so now I’m not sweating in it anymore. Very good price too, Highly Recommend.

There just isn't enough airflow to make a difference, it helps slightly, but maybe a 10% improvement. Wearing a mask is just miserable for me, and this didn't significantly improve it. I think that you just cannot put out enough watts from a battery that small. A better design would be a bigger battery that fit in your pocket and had a cord or something, that way the fan should run at a higher rate and pump more air over your face.
