CarboAir 50-4", 5", 6", 8", 10", 12" - Professional Carbon Filters (125x330mm - Max Air Flow 480m3/h)

Terrible quality. After a connected and started fan black charcoal dust fly out of filter on my room make everything dirty. I can't use it because it is so much dust coming out from filter. A highly not recommend to anybody used this company it's very bad quality product spend little bit more money but get good quality filter
