Plug. Play. Believe.
iFi's AC iPurifier is for anyone whose audio is troubled by interference or distortion caused by dirty mains power.

It will rid your system of electromagnetic (EMI) or radio-frequency (RFI) interference and brings clean, clear sound to your audio in an instant.

It is available for UK (via an adapter), EU and USA power sockets and can handle from 100 240 volts.

Military grade
The AC iPurifier uses iFis Active Noise Cancelation technology inspired by military engineering.

It ACTIVELY eliminates far more noise across the frequency range than a passive product, even across the lower frequencies.

No harm. No hum.
The AC iPuriifier boasts inbuilt earth/ground and polarity detection.

You can always be certain the polarity is correct and that you have the necessary ground/earth connection.

No harm. No hum.

Smart thinking.
iFi's Intelligent Ground system ensures the AC iPurifier will not introduce a ground loop when one isnt needed.

Use the 4.4mm grounding socket safe in the knowledge that the AC iPurifiers smart thinking will keep your system ground loop free.

No ground loops mean no annoying hum or buzz. Now, thats music to iFi's ears.

Safe and sound.
And with in-built surge protection, the AC iPurifier will shut down if it detects a short or a power surge.

Your equipment will remain safe and sound.

Many hands may light work
And the same can be said for AC iPurifiers The more you use, the cleaner the power.

And, you can also add them to your power strip. Why not separate your digital and analogue devices to lessen noise contamination even further?

Features

• This is an active not a passive product. As can be seen from the graph, it cancels far more noise across the frequency range than a passive product.
  
  Active filtration is MUCH better in the lower frequencies, at -40dB. Passive filtration is only truly effective in the very top-end of the frequency range.
  
  Discover more about passive v active filtration and noise contamination here.
• Based on military technology originally used in aircraft, iFi's Active Noise Cancellation® (ANC) generates a signal identical to the noise signal but in the exact opposite phase to actively cancel all incoming noise.

• iFi's Wireless Purification System (WPS) is a complex circuit that reduces power line noise without audible or measured side-effects.
  
  This is important because other solutions, while attempting to curb noise, also hamper dynamics.
• The LED indicators show Polarity and Earth detection. As usual, green is good, red signifies an issue.
  
  There are four possible combinations and these can be found in a brief table in the User Manual. This tells you what the issue is and suggests how to remedy it.
• iFi's Intelligent Ground is a smart diagnostic tool.
  
  It only actively provides an earth/ground connection if your system needs one. It will NOT create a ground loop even if the system is already earthed/grounded.
• The Over-voltage Surge Protection (OSP) is an auto detection and cut-off circuit.
  
  Should it detect an excessive power surge or short in the mains electricity it will automatically cut off. If this issue persists, it will not reboot and will protect your equipment from harm.
  
  It is effectiive to max. 30,000A @ 1,000V/10uS.
• You can use multiple AC iPurifiers simultaneously in your system.
  
  The more AC iPurifiers you use, the cleaner the overall power. If the AC iPurifier is placed in the middle of a power strip, it will also act as a noise shield. Noise is reduced, isolated and confined to the respective left/right sections of the AC iPurifier.
