The iFi Audio AC iPurifier includes Active Noise Cancellation technology to cancel all incoming mains noise and cleans up noisy mains supplies.


Hydrate your hearing.

You deserve the best in home audio, and the AC iPurifier does just that. Drink in crystal clear music once more.

The tech spec.

The AC iPurifier draws from French military engineering and includes:

  • Active Noise Cancellation to cancel all incoming mains noise

With EU and USA 3-pin versions. It can handle 100 volts to 240 volts. The UK version comes with adapter to EU version.
And with a chassis made from polyurethane plastic, the AC iPurifier is not only powerful, it’s tough too.


Cleans up noisy mains supplies.

It ACTIVELY cancels noise. The AC iPurifier cancels far more noise across the frequency range than other passive products. Active filtration is MUCH better at -40dB and effective across the frequency range as this graph shows. A passive purifier filters only in the very top-end of the frequency range.


Active Noise Cancellation.

By generating a signal identical to the noise signal but in the exact opposite phase, our Active Noise Cancellation® (ANC) actively cancels all incoming noise!


Multiple plugs

Modern audio systems have a plethora of mains plugs. Each of these add unwanted noise issues and pollute the local mains supply. You can insert into the AC mains wall outlet that supplies the audio system OR insert into the mains extension block for the audio system. The design of the AC iPurifier is such that it is even more effective if several are used to ‘contain’ the same type of noisy sources. Try in different locations to discover which has offers the most improved sonics.

Wireless Purification System.

This reduces noise without audible side effects. It does not hinder dynamics.

Intelligent Ground Connection.

It only actively provides an earth/ground if your system needs one. It will not create a ground loop. Especially interesting with the Zappiti Pro 4K HDR.

Smart Polarity and Earth Connection.

Insert into your system to check polarity. Red - incorrect. Green - good to go.

Saves your system!

If it detects a power surge it will automatically cut off, protecting your valuable and highly sensitive equipment from harm.
