AC iPurifier
Key Features
Active Noise Cancellation
The AC iPurifier uses Active Noise Cancellation to cancel all incoming EMI or RFI noise. This is the same tech as in active noise-cancelling headphones!.
Polarity Earth Diagnostics
The AC iPurifier’s smart diagnostics system helps to avoid potential issues by indicating both correct
polarity and whether the system has a ground/earth in place.
Intelligent Ground
iFi calls this circuit Intelligent Ground because it will not create a ground loop (a common cause of buzz or hum) even if the system is already earthed.
ACTING ON INTELLIGENCE
The AC iPurifier is clever too. When used with USA and EU type mains plugs, its Intelligent Polarity feature will automatically tell you whether you’ve got them plugged in the right way for whichever country you’re in. A green LED indicates you have a red LED means you haven’t.
PURE SILENCE, PURE MUSIC, PURE JOY
This product is designed to clean up noisy main supplies to audio systems. Technologically advanced, its Active Noise Cancellation(ANC) circuitry can eliminate far more noises across the frequency range that other passive devices.
How do I use?
AC iPurifier
Insert into the wall outlet that supplies the audio system with main electricity OR insert into one of our power stations or any extension block powering the audio system.
Product Reviews
★★★★★With the iPower2 the noise disappeared completely with the volume at maximum! That silence is what I expected. I heard the music better! The ZEN Air phono with the addition of the iPower2 goes from being a surprising device for the price, to being surprising for its performance
Guido Ruiz Barría, Surcos de Jazz
★★★★★The iPower X fever-level transformers introduced this time provide the purest DC power supply equipment. Power supply, iPower X is an AC / DC transformer with extremely low noise. Its small volume is filled with a lot of ifi Audio’s exclusive technologies and fever materials
My HiEND Magazine
★★★★★I believe it is a great everyday carry accessory not only for sensitive IEM/Headphone users but also for beefy headphone amplifier owners who would like to hook up their IEMs to these amps and crank the volume as far as they can. The iEMatch 4.4mm gets the highest recommendation I can give to an audio accessory.

★★★★★The iPurifier 3 is a USB gadget that reclocks, regenerates and has a rebalance tech, it incorporates a active noise cancelation technology that works impressively, a revised and upgraded version of the last itineration of their iPurifier 2 I also own, as always the unbox experience of the package from iFi products is very specia

Frequently Asked Questions
Yes
It does not use SMPS, it has a special linear power supply unit that works for all mains voltages.
The AC iPurifier polarity LED indicates that there is a significant voltage between neutral & earth, which normally indicates wrong polarity.
Yes, it is compliant with CE and all related, relevant harmonised safety standards.
The noise reduction system has two components, one that attenuates differential noise (between live and neutral) and one that attenuates common mode noise (between live/neutral & earth). Differential noise reduction (differential noise is noise between live & neutral) remains active even without earth reference. If there is no earth/ground reference (two red LED’s) there is no “reference” for the common mode noise reduction circuit.
