Been using this mask for the last 5 years.
Have been using this mask and it is very comfortable more because it wraps around the head rather than resting on the ears
The first mask I got was defective, however on giving the feedback , the faulty mask was replaced.
Thanks for the review Roy. Neomasks do quite well and a LOT of people use this mask for running, cycling as well as for walking and commuting on their vehicles in our polluted cities. The simple replaceable activated carbon filter is also important to keep subsequent costs low and yet maintain clear breathable air.
