Contacted AusAir about losing components from my mask and they were kind enough to send a replacement set.
Best mask there is. I lived in California within 90 miles of the terrible wildfires and just relocated to Washington state which has them also. This mask has saved my life, no question. I have severe asthma and was able to breathe without difficulty with this mask. It has attracted lots of great attention for it looks and then about how it’s made.
