Verified Buyer

After putting the mask through it's paces, I couldn't rate it enough Verified Buyer

I wear the mask when walking through the centre of London for half an hour, two times a day. The mask fits well and keeps my nose and mouth covered. It does it's job, I can't smell the pollution or cigarette smoke - which I was really happy with as I have a strong sense of smell! The filter feels substantial, I feel protected from the polluted env ironment in built-up areas. I would say follow the fitting guide correctly and you'll get a good fit, the side adjusters and back strap work together so that you can make it secure around your face where you feel you need it.
