- great product
working overseas with lots of air pollution and mask works great, I can breath easier with it on and have recommended it to all my friends. I think two will be ordering the mask soon from your company. great product only wish it was in desert tan and replacement filters were cheaper, but works great. thank you.
- Has helped me stay at my job
I am so grateful these filter work as well as they do. I am able to remain working as head audio engineer a theater I have been at for the last 4 years. I love working there except for the 45 year old dusty curtains. Thank you AchooAllergy and Techno for making this awesome product available. You both ROCK!!!
