Supposed to help eliminate clumping at the end of output tube and overcharges..

I heard it on the internet, so you know it has to be true, they can't say things on the internet that are'nt true....

I never did a before/after test, , and thought well it is a small piece of a straw, so it is free, if it turns out to be bull I'm not out anything.. so I put it in.. if you are not having over charges don't worry about it..
