They reduce the transmission of high-frequency radio waves. The
density of such waves around us is increasing because of cell phones
and the proliferation of other wireless devices.

Their presence indicates that they are a fix for a problem that some
users must have had. RF problems are highly local in nature; you
might never experience them, or you might have them all the time if
your house is washed by a radio station, taxi dispatch center, or
cell phone tower. It's likely you won't have any problems out in
quiet places, but I'd keep the filters in your kit just in
case...they must be there to fix a vulnerability that was discovered.
