As has been discussed in other threads, I hear no negatives to always having the Westek or CSPort on. The effective range of the Westek is 12” according to their docs and my cartridge is beyond that. Probably depends a lot on where you live. It is brutally cold and dry where I am. Even with a central whole house humidifier and geothermal heat it’s not possible to keep the humidity at a reasonable level in the winter. It sure helps keep the records clean when there is no static charge on them. I use no brushes or anything else to wipe the surface.
