Analogue buff? Digital junkie? Or like a bit of both? Our AC iPurifier will purify and protect your system.

Plug. Play. Believe.

Our 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.

iFi audio AC iPurifier

Military grade

The AC iPurifier uses iFi’s Active Noise Cancellation 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.

Our Intelligent Ground system ensures the AC iPurifier will not introduce a ground loop when one isn’t needed.

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

No ground loops mean no annoying hum or buzz. Now, that’s music to our 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?

EMI (Electromagnetic Interference)

EMI is a type of interference caused by errant and unwanted electromagnetic waves that are received and amplified by an audio system. They cause some of the annoying ‘audio gremlins’ we often talk about.

RFI (Radio-frequency interference)

Radio-frequency interference (RFI) is very similar to electromagnetic interference (EMI) but is found in the radio frequency spectrum. It is another source of irritating, unwanted noise often talked about as an ‘audio gremlin’.

Top tip: just don’t add water.

Active Noise Cancellation

Active Noise Cancellation (ANC) reduces unwanted sound by the addition of a second sound wave specifically designed to cancel out the first. This basically results in no sound at all as it reaches unwanted sound even at the lowest frequencies.

Passive noise cancellation is done by means of insulating filters and works best on the middle to high frequencies. It does not work on the lower frequencies meaning that some sound can still be heard.

Polarity

In simple terms, polarity refers to the way a signal flows.

Audio signals generally flow one way, like DC current, and have positive polarity. Inverting the polarity can have a negative impact on sound and equipment.

Ground Loops

In an electrical system, a Ground or Earth loop occurs when two points of an audio system both have a ground reference which causes a ‘potential voltage difference’ between them. Ground loops are a major cause of the noise, hum, and interference in audio, video, and computer systems.

Our 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.

Our Intelligent Ground is a smart diagnostic tool. It will only actively provide an earth/ground connection if your system needs one. It will NOT create a ground loop 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 effective 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.

Try in different locations to discover which has offers the most improved sonics.

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.

Based on military technology originally used in aircraft, our Active Noise Cancellation® (ANC) generates a signal identical to the noise signal but in the exact opposite phase to actively cancel all incoming noise.

Read more here.

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.

Removed a persistent 60Hz low levl “hum” n an instant

Removing the 60 Hz hum was very nice by itself. But it also opened up the soundstage, clarified female voices, and made music, especially HDCD recordings, and Reference Recordings, much more enjoyable.

Good surge protector and mains conditioner

No doubt I will be told it is bias talking, but this makes an appreciable difference to my ears on sound quality when plugged beside the socket powering my Naim Uniti Star and PMC speaker combo. Plus, it adds a degree of surge protection. Money well spent in my book.

Amazing upgrade

I only ordered the Purifier on suspicion, but then I was really surprised how the device affected my stereo. Until now, I paid little attention to the power source, except for the phase-out of the sockets and power plugs, and was astonished after this upgrade: better spaciousness and higher accuracy in the representation of my vinyl treasures. I’m convinced and bought me a second purifier for my digital devices right away.

Test: iFi PowerStation power strip and AC iPurifier

Thorsten Lösch, the busy developer of iFi Audio, surprises us again and again with ingenious solutions on the subject of HiFi. And because more and more electronic users put more and more loads on the power grid, it would be a miracle if Lösch didn’t have some ideas ready here too. One of them is the iFi PowerStation power strip, which of course is anything but a “normal” power strip …

Cleaned things up great

I use 4 of these throughout my home theater system. I have 4 dedicated 20 amp and 2 dedicated 30 amp lines for the room and had some slight ground hum. Using these made all the noise disappear with no loss of dynamics or sound quality, for the price they can’t be beat,

Amazing … but effective

Originally purchased to electrically phase my hi-fi and video devices.

We then see the randomness of the location of the phase behind the wall outlet.

We can also contater that sometimes the phase is also reversed on the sector bar …

Since all these phase concerns have been resolved and with the joint use of the IFi purify my feeling is the following:

The precision and the quality of the soundstage are better.

I also specify that my electric line for the hi-fi is not separate and direct to the switchboard.
This might explain that.

Noise is gone!

Many outlets in my 1950’s house are not grounded. This is obviously something that needs to be addressed. However, in the meantime, these AC purifiers really do the trick. I added one at the outlet and another in the power strip and for all practical intents and purposes my noise problems are gone. I am very happy with this purchase.

Awesome product. NOT snake oil! WORKS

My turntable was picking up some AC line noise caused by a powerline network adapter running on the same circuit. Plugging this device into the first receptacle of my power distributor (ZeroSurge 8R15W-I, which by the way does nothing to attenuate line noise in my tests) greatly reduced the audible noise (I’d guess at least 10db).

I purchased this device based on a YouTube upload titled “iFi AC iPurifier review — PROOF that it works!” and I can confirm my result is similar to that shown in the video. A single AC iPurifier is not canceling ALL the powerline AC noise, but I’m impressed because truthfully I was expecting it to do nothing.

Great for stopping the ground loop

I use it on my Zapitti Pro 4k hdr following a ground loop problem, the problem was solved in a few seconds, moreover it allows the Zapitti Pro 4k hdr to behave better .. My only criticism is that the rca cord (male) is not provided, I had to buy the Groundhog + pack. It is a very good investment to accompany the hdg gear ..

great device

Like many reviewers, I am also enthusiastic about the line filter.
I personally find many other line filter devices in hi-fi and high-end areas often very overpriced, since the actual filter modules are in many cases industrial mass-produced goods and have been technically developed.

Since the iPurifier is designed as an active parallel filter, the sales price for this product appears appropriate.

Works for My Situation!

It’s quite a while since I bought something for my hifi system, but as I was getting back into it again I thought “Why not?”

I came across this product via a YouTube video, and thought it might be a bit ‘snake oily’, and was expecting to send the unit back – especially as I already have a higher-end Furman power conditioner in use to clean up what can be a pretty horrible power supply – but … WOW!

The first thing I noticed was the bass – there was too much of it. Now, I’m really good at setting my subwoofer up, so I wasn’t expecting any difference at all, but I had to lower the level and adjust the cross over setting. After that, I was hearing into the recordings more, and leaning new things about albums I’ve known for decades.

I think a product like this requires a dirty mains supply to show its worth – hence the range of reviews here. For me, it is one upgrade I really appreciate!

works for me, probably depends on how filthy your mains is

This works, I suspect its going to depend on your own particular mains as to whether it helps.

Why have I waited till now!

When I believe the system can’t sound any better something surprises me and it does! I’ve been into hifi for years and I’m really annoyed with himself that I’ve waiting to now to try this! There is an improvement on all sources but on vinyl it is incredible. Definitely recommend using the smart earth.

Used for overall home health

I use this for EMF protection and to eliminate “dirty power lines” in my home. Noticeable reduction in general anxiety when two units plugged into the apartment. The only hifi unit I know of that can power condition an entire home, rather than just a limited set of plugs.

The little extra that completes a good HIFI installation!

First thank you to elite audio broadcasting for the telephone reception and the relevant advice; fast delivery and well-packed package in addition. the first listening confirms the gain in hearing quality and reduction of background noise. plugged into the first outlet of the power strip, the device does the job and it does it well! 

It is a good acquisition which for a reasonable price allows a more important in audio quality; knowing that it also makes it possible to know if the current phase is good as well as the earth; it also provides effective protection against overvoltages! I think it must also bring a plus in video installation ……. for the HIFI in any case it works!

I found this to not be a solution, but an enhancement

The difference was indistinguishable when directly connected to dirty mains. No configuration I tried, nor sockets seemed to have any effect. Treble has been horrifically harsh in my flat, I even forged a hookup to utilize the ground point. Holding back, I did another examination but this device seemed to have no effect. I found exorbitantly sibilant tracks were again unaffected, with identical tonality.

Where I was surprised was when I used the iPurifier with a mains conditioner, there is a clear difference in fidelity. Robert Plant has some wonderfully produced, and so I listened to Trampled Rose from the album Raising Sand, one of my favourites. I noticed a quiver in Alison’s voice at around 3:50 became more distinct. Paying attention to the drums I then noticed they were flat when I removed the IPurifier. Wow! I am mindblown.

It works! Reduces noise from AC line for less than other conditioners

Great for making your music sound clearer and come from a more silent background. You have to use the device for a while, and then remove it to appreciate what it does. This is not a fix all, though. Many power supplies inside gear generate noise and this can only help reduce that pollution from reaching another component over a shared AC circuit.

All your electronics need low noise power supplies or modified to have them before you can realize your system’s full potential. Even unplugging unused components can help reduce noise they put on the AC power.

Overview of iFi Audio accessories and filters – does filtering matter?

This article was born in my head a long time ago, mainly due to repeated questions from time to time, whether I had contact with filtering devices like iSilencer, Jitterbug etc. But since I run my humble blog, I’ve probably got used to most people to a few maxims, which I am guided in total not only in the field of audio equipment, but generally in life…

Cleans up the sound with a difference you can hear

I use a line conditioner, and thought my power was clean, but surprisingly, you plug in the IFI and you can hear the sounds become more clear and focused. Go back and uplug and you can hear the sound not be as focused and clear. A wise investment if you are sitting on the fence. I’m happy, now I just keep it plugged in all the time!

Feels like I purchased a new AV system!!!

This by far one of the best audio product I have ever purchased. I honestly didn’t believe EMI could cause so much harm to the audio quality.

For me, It improves the overall sound, including: imaging, instructions separation, eliminated or terminated harshness, sorround sound has more air, and also, I now get to enjoy music at lower volume. I stream Tidal, and it sound so smooth now that I end up grabbing three of this.

I am a fan now. Thank you ifi.

Fixed Noise from Powerline Internet

I have a couple small music rooms at my home that include three powered wedge floor monitor. When I added some powerline network adapters to my home, the monitors started making terribly loud digital clicking sounds. I tried routing the monitors through an APC UPS, Furman PST-8 Power Conditioner, and used ferrite beads on all my cables.

The noise on two of the monitors reduced a little, but the third was still almost unusable. The AC iPurifier seemed a little expensive, but I figured I would give it a shot because I was out of options.

I tried the AC iPurifier first on the powerstrip that the noisiest monitor was connected to and it reduced the noise a little but it was still very audible. I then moved it to the wall outlet the powerstrip was plugged into with similar results. At this point I was feeling pretty hopeless, but decided to try one more thing. I plugged the AC iPurifier into the outlet above my powerline adapter that’s connected to my router. Instantly the noise in the monitors was gone. Problem solved!

Improvement is real but you need 2.

I got 2 of these. Originally I thought I would return one. But now both stay after I recorded a few samples with different configurations. I tried 3 different configurations:
1) one on the wall outlet my power strip attached to.
2) one on the power strip itself.
3) With both attached as described in 1) and 2), treble and bass quality significantly improved compared with just having one installed.

Money value is lowered because you need two at least to make it shine.

Excellent product, can deliver significant improvement to sound quality

If it’s working well but it could be even better, this will help it along very nicely … with more ambiance and detail and, most importantly, a better sense of timing to the music. I use mine in conjunction with audiophile mains leads (Nordost and Furutech), power conditioning units (Nordost, ISOL8), etc where you think it might have less opportunity to improve things, but it certainly works for me. I use two and am thinking about more. Another iFi power conditioning winner, along with the excellent DC iPurifier 2 (of which I have 6 or 7)!

iFi AC iPurifier review: goodbye, power noise

In regards to noise reduction, the iFi AC iPurifier works as advertised – it removes a lot of noise and makes it more bearable. It is also incredibly easy to operate and fits any power plug (in my case it’s an EU plug, but there is the USA plug also available).

There are multiple factors that can lead to electrical noise in a system, but the AC iPurifier is in fact a quick and effective solution that is not even that expensive. With its ~$100 price tag, it is affordable and can be considered an investment to surely improve the quality of the sound. Contrary to other things (i.e. cables) that may be considered pure snake oil by some, this works.

It Cleans The Electrons Of Your Power Outlet!

You plug it to the AC mains wall outlet that supplies the audio system or into the mains extension block for the audio system separating analogue digital equipment, and it automatically takes samples of the current from your socket to perform an optimal filtering.

Through the ANC technology (Active Noise Cancellation) and WPS (Wireless Purification System), the AC iPurifier calculates and sends a signal back to the socket that cancels the perceived noises. On the other hand, it protects the equipment against voltage surges, detects lack of ground in the system and if the polarity is correct. And if that were not enough, it has an intelligent ground connection (Intelligent Earth) that you can use to connect the ground of all your audio equipment, but it only works if necessary, further avoiding more ground loops.
