Seen it many times, and as mentioned, if one phone/satellite receiver/fax/etc either doesn't have a filter, or has a bad filter, it can cause static on all the phones just as if you didn't even have filters.
It may be a redundant question, but you should double check each filter also and make sure each device is plugged into the phone side, and not the DSL side of the filters. Do you by chance have a house alarm system? If so, then even it needs a filter!
