The DNA Line Filters by Nobel Electronics are very interesting and effective pass-through or in-line (series) filters. They differ from most other filters out there which are parallel filters by design. With the DNA Line Filters, the electricity you are using passes through the "filter" which acts as a barrier for dirty electricity. Dirty electricity on the outside is blocked from coming in. Great for isolating yourself from the power grid, neighbors, digital or smart meters, and solar (photo-voltaic) systems.
