Review on 🔬 Advanced Chemical & Particle Filtering System by Respro by Erick Bowers

. However, when they arrived the size was marked Large. Looking again for different mask filters I found that nowhere is the size mentioned and it is best to zoom in on the photo to see if the point was Sm, Med or Lg. It seemed like only large filters were available, but you wouldn't know that by reading the product descriptions. Now I have to figure out how to get them back on Amazon. At this point I'll probably just buy another mask. Disappointing experience.
