I used one year in the wear of daily 6 hours. The beginning is good, but you will not contact the silicon surface out of shape. If you check the back of the intake valve at the time of filter replacement, and faint with dust. Brass Chick part will come cracking and deterioration crisp. Durability of the mask, not recommended if seek the confidence of the filter.

Although I bought the thing is the size did not choose, painful hit nose like was a little small. Bought part of the plastic in three to four years after becomes unavailable cracked tattered cracked the entire deteriorated.
