Vogmask Blue CV N99 Carbon Filter and Exhale Valve / Large (over 120 lbs)

I bought two of these masks to wear while riding a motorbike in Vietnam. I can't speak for their effectiveness in filtering dirt from the air.The drawbacks are that (1) the fit is a bit too snug leaving very little to no air space between the mask and my face and (2) wearing this mask causes my eyeglasses to fog up. The fogging happens mostly when I stop at a traffic light. When the light changes I can't see for a few seconds until the wind blows off the moisture as I start moving. So I ended up only wearing this mask when traveling to extremely dirty and dusty areas. I used a simple cloth mask the rest of the time.

I bought this mask to use at work. I have been a hairdresser for 40 years. Last year I was diagnosed with occupational asthma. I now have to wear a mask while applying hair color, spraying hairspray or while around other chemical services. i was using a surgical paper mask. Not Acquitted. This mask was worth the money. I like the ear loop..doesn't mess up my hair. I got it in a color that matches the decor of my salon. I do not smell anything while wearing it..not even hairspray. My glasses no longer fog up and the breathing is easy.

I ordered this mask for my upcoming year of study abroad in China. I paid extra for the blue mask because I really like the color, and expected to receive a product for that price. Instead my mask did not have the exhale valve pictured. Now I have to scramble to try to return this one and get the correct mask before my flight leaves. Very frustrating.Update- returned the first mask and got a replacement that also did have have the advertised valve. So done.

The vent was out of place.
