Air Systems BB60-A BB60 Replacement "A" Filter - 1st Stage OLD PRODUCT NUMBER: BB50-A Air Systems International introduced the first portable breathing air filtration system in 198 4 that was used in the closed position-the Breather Box. That product, called the BB50-CO, has been the state of the art for breathing air filtration for over 40 years. Today in 2025, we have improved our breathing air portable breathing filtration unit to meet the demands of the 21st century.
