When only a blue filterglass is used it is the UVB filter. When a clear glass and a blue glass is used the clear glass is the UVB filter. In this setup the clear glass is closest to the lamp and the blue is closer to the client. The most current blue filter is MUG6. Oh, and hoser, you don't even have any
equipment with high pressure so you have no idea. And again, filterglass does not solarize.------------------Friends help you move, Real friends help you move bodies.
