Respro Techno Mask Filter - LargeRespro Techno masks have replaceable charcoal / HEPA filters. Simply replace these mask filters when breathing becomes difficult or there is a noticeable change in performance. For extended storage periods, the filter should be removed from the shell and allowed to dry before storing. All used filters should be discarded. 2 replacement filters per pack.
- 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!!!

With the XL mask it can fit either the XL or the L filters.
Hope that helps!
