Question

Do broadband dsl filters wear out?

Do broadband dsl line filters ever wear out or go bad and need replaced?

Answer 1

The DSL filters have nothing mechanical to really wear out but the capacitors in the dsl filters could go bad which is rare.

If you notice noise on the phone line or your DSL keeps dropping when you get a call on the phone then the DSL filter could be bad and need changing.

So other than the capacitor going bad or lightning striking the DSL filter the DSL filters are pretty reliable and don't wear out.
