NUENUN 5 Pack Unisex Adjustable Reusable Washable Dust Protect Mouth Cover with 10 Carbon Filters and 10 Breathing Valves for Bicycle Running Riding Cycling Outdoor Sport Black

I use for work and they hold up pretty good

Easy to use but the velcro doesn’t work at all, If you move your head to the sides it takes off

Seemed to be good protection from all the spring time pollen in Nebraska….which there was a lot!

Hay que alarmarlos y cuando lo logras la forma no es anatómica y son muy incómodos. Realmente un producto muy mal desarrollado.

Good, but same as original base camp model defect. The ear straps are useless and won't stay put when talking or moving head a lot.

They just arrived, we opened them up, put them together, and tried them out. Heres my impressions. Putting the filters together without instructions can be flustrating. But with some thought it can be done. Put the filter in the back side of the front peice push the back peice into it and turn it till you feel a click. Open the front sIde and take the piece of rubber/plastic out and youre good to go. It fits both myself as a large man and my 10 year old daughter.

I'm impressed for the price.

The reviews seem to practically rave about these things and I had to take a close look at the product on here to make sure I didn't get the wrong one or something. The mask is very loose. I imagine it falling off regularly. The way the mask and filter go together is uncomfortable. The nose piece doesn't sit on my nose. The entire point of buying this was to vent my breathe away from my safety glasses when I wear a mask this doesn't do that well. It's loose and uncomfortable. I don't know what the other guys reviewing this are taking about. I would wear a shirt sleeve as a mask probably more comfortably.
