Optical Galvanic Isolation brings even greater silence to your network-connected audio system.
The iFi LAN iPurifier Pro is an ethernet noise filter with optical isolation designed for music streamers, 4K media boxes, and media streaming PCs. It helps your network device perform exactly as it was designed to—free from interference originating from routers and network switches—so you can enjoy a quieter background, improved timing, and purer sound.
The LAN iPurifier Pro utilises Optical Galvanic Isolation technology to effectively isolate and eliminate electrical noise and interference emanating from the router or network switch, helping to maintain absolute silence and purity for your network-connected audio system.
Increased system noise can amplify a streamer’s jitter, reducing performance and leading to a more digitised sound that lacks richness and authenticity. The LAN iPurifier Pro helps by isolating electrical noise and interference, reducing system noise and errors from the router or network switch. By converting LAN data to optical and back again, it achieves Signal Regeneration and Jitter Elimination in one compact device.
Simple and elegant to use—no complex network setup required. With a standard LAN input and an optically isolated LAN output, connect the LAN iPurifier Pro between your router and your network device, placing it as close to the network device as possible for best results.
The LAN iPurifier Pro is powered via USB-C, leaving room for easy power upgrades. You can upgrade to iPower2 or iPowerX to enhance overall performance. iFi’s iPower2 is an ultra-quiet, ultra-clean audiophile-grade power supply featuring Active Noise Cancellation II to cancel incoming EMI and RFI, helping reduce noise and graininess. It is stated to be more than 10× quieter than most audiophile power supplies.

Plug and Purify
Whether you're a network novice or an audiophile aficionado, the LAN iPurifier Pro offers a simple, elegant solution for ethernet noise filtration, a feat previously achievable only through complex setups. With a standard LAN input and an optically isolated LAN output, simply connect the LAN iPurifier Pro between your router and network device, positioning it as close to the network device as possible.
Isolation, Regeneration and Elimination
Increased system noise significantly amplifies the streamer's jitter, diminishing its performance and resulting in a more digitised sound that lacks the richness and authenticity of true audio reproduction. The LAN iPurifier Pro features Optical Galvanic Isolation to isolate electrical noise and interference, reduce system noise and errors from the router or network switch. Optical Galvanic Isolation technology converts incoming LAN signals into optical (light) signals and back again, accomplishing Signal Regeneration and Jitter Elimination.
Maximise Performance with iPower
Audiophiles always pursue perfection in their audio systems, and we've ensured there's room for you to upgrade. The LAN iPurifier Pro is powered by USB-C, allowing you to upgrade to iPower2 or iPowerX to enhance overall performance. The iFi iPower2 is an ultra-quiet, ultra-clean audiophile-grade power supply, featuring Active Noise Cancellation II technology to cancel out all incoming EMI and RFI noise, you’ll never feel powerless against noise and graininess again. It is more than 10 times quieter than most audiophile power supplies.
