The USB iPurifier Pro from iFi Audio is a noise filter for USB ports. The successor to the iGalvanic 3.0, it also includes the feature of the iSilencer and iDefender for a unique and ever more powerful product aimed at audiophiles. Compact yet comprehensive, the iPurifier Pro protects the signal from USB interference to ensure high-quality transmission.
Although the iPurifier Pro USB incorporates a wide range of features to reduce noise, it does not compromise on speed, allowing data transfer speeds of 10Gbit per second.

Thanks to its galvanic isolation, the USB iPurifier Pro isolates the input and output circuits, eliminating parasitic currents that could cause noise and jitter. The active noise reduction (ANC) function duplicates parasitic noise and reverses the phase to eliminate it, restoring a clean, noise-free signal. Finally, to avoid ground loops, IsoGround technology provides grounding via its 4mm port (compatible with the iFi Audio GroundHog+, sold separately).
