Furutech Flow-28 NCF Power Filter

Unlike a standard surge protector that primarily guards against voltage spikes, the Flow-28 NCF is an inline filter designed specifically to clean up electrical noise. It uses advanced materials to dampen EMI and RFI interference that can degrade audio and video signal quality, rather than just protecting hardware from power surges.

No. The Flow-28 NCF is engineered to remove noise without limiting current flow. Because it uses a parallel circuit design, it effectively filters out high-frequency interference while allowing your components to draw the power they need for full dynamic range and detail.

The Floating Field Damper is a patented Furutech grounding system that prevents the buildup of electrical potential on the connector's metal parts. By effectively grounding these stray fields, it reduces distortion and helps maintain a cleaner, more stable signal path for your audio components.

Yes, the Flow-28 NCF is designed to be installed inline between your existing power cable and your component. It features standard IEC connectors, making it compatible with most high-end audio and video power cords.

For the best results, place the filter as close to the component as possible—ideally directly at the power inlet of your amplifier, DAC, or media player. This minimizes the length of cable that can pick up interference after the power has been cleaned.

The device is maintenance-free and requires no special handling. Like many high-end audio components, you may notice the sound quality settles and improves slightly after the first 50 to 100 hours of use as the materials stabilize.
