Shenggetu Pollution Mask Adult Anti PM 2.5 Pollen Dust Mask Washable Anti-fog Anti Dust Mask Antibacterial Earloop Mouth Mask with 2 Filters

Although it's light and compact, it's also hard to strap it to your face in the right way, to properly seal out the polluting air.And if you wear spectacles/glasses, they will steam up a lot when wearing this mask.

It's a nice mask, you have to breathe deeply in order for it to work properly as the mask doesn't perfectly fit to the face, the biggest problem I have is that it's too small and doesn't quite fit over my mouth and chin properly causing it either slide up and get in my eyes, or slide down and become useless.

Fast delivery and easy to use. Comfortable. Inserting the filters correctly was not obvious though. Used while in China and was comfortable all day.

It was used from people brush up in a dusty factory done its job

I am absolutely in love with this mask! Overall, this is a great mask and I would recommend it for anyone who deals with smog or air pollution on a regular basis, or maybe just wants to filter out viruses and bacteria on an airliner.

It seems okay. I bought it to help with my hay fever as it claims it filter out pollen. But I wear glasses and this mask makes my lenses fog, making the mask almost unwearable.

I like this mask. works well for me when cycling ,even on really polluted days, and was pretty cheap. Good value for money.Happy with my purchase!

Bought it to wear it smokey work environment. Still lets some smoke in.
