iFi Silent Power AC iPurifier 2 Power Filter

Silence Starts at the Socket.

The AC iPurifier 2 is a complete mains conditioning solution that tackles EMI/RFI and earthing issues before they reach your AV system.

With patented Active Noise Cancellation III technology, it reduces mains noise by over 100x while providing intelligent diagnostics, surge protection, and a supplementary earth connection for total system stability – all in a compact, plug-and-play form.

Running in a parallel configuration, the AC iPurifier 2 delivers uncompromised power without any detrimental effect to the dynamics of your audio system. The result is a clean power foundation that reveals greater depth, silence, and clarity.

Key Features

• Active Noise Cancellation III: The AC iPurifier uses Active Noise Cancellation to cleans mains power.
• Polarity & Earth Diagnostic LEDs : The AC iPurifier’s smart diagnostics system helps for optimal system setup.
• Built-in Surge Protection : The AC iPurifier 2 has a built-in surge protector that protects against spikes.

Smart Diagnostics.

Unlike other power conditioners, the AC iPurifier 2 does more than just reduce noise – it also functions as a plug-and-play diagnostic tool for your mains supply.

The AC iPurifier 2’s LED indicators confirm when everything is running as it should – or quickly flag any wiring, polarity, or earthing issues for fast troubleshooting.

Noise, Cancelled.

Alongside improved circuitry and upgraded capacitors, the AC iPurifier 2 features our latest Active Noise Cancellation III technology – a significant step up from the previous generation.

Inspired by military radar tech, it targets EMI/RFI on the power line and generates an inverted signal to cancel them. The measured noise then drops by an impressive 40dB (100x) in comparison to standard filtering methods.

The result is an unprecedentedly quiet, pitch-black musical background, richer retrieval of detail from your audio, and complete isolation from household electrical interference, allowing your system to perform at its absolute purest.

System, Protected.

Ground Control.

Does your system hum and buzz fade when you touch your device?

Pair the AC iPurifier 2 with the Groundhog+ kit, and its 4mm port provides a dedicated supplementary earth connection – safely channelling noise away from your system.
