What is the best EMF protection for a phone?

For most people, the best EMF protection for a phone is a discreet, scientifically-tested neutraliser disc that works with 4G, 5G and Wi-Fi without blocking signals. Aulterra Neutralizer Discs are our top recommendation because they are independently lab-tested, peel-and-stick easy, and backed by thousands of happy customers worldwide.

Do EMF phone stickers actually work?

Cheap generic "anti-radiation" stickers often have no published research behind them. Aulterra Neutralizer Discs are different: they use a patented paramagnetic mineral blend shown in independent magnetometer testing to re-organise chaotic EMF signatures around the device into a more coherent pattern — without reducing your signal strength.

Will a neutraliser disc block my phone signal or 5G?

No. The discs do not shield or block the signal — they work at a subtle, energetic level. You keep full 4G, 5G and Wi-Fi performance. If a product claims to "block" EMF from a phone, it will also make your phone drain battery and drop calls.

Where should I place the disc on my phone?

Clean the back of the phone with a dry cloth, then peel and press the disc firmly onto the back (usually centred, or behind the battery area). Leave it in place 24/7. If you use a case, the disc can sit under the case — it is thin enough to be unnoticeable.

Is one disc enough for a phone, or do I need more?

One disc per phone is the recommended coverage. The 3-pack is our most popular option because most households also want protection on a laptop, tablet, router, or a second family phone.

How is this different from an EMF-blocking phone case?

EMF-blocking cases work by reflecting radiation away — but when you hold the phone, that reflected signal can actually increase exposure on the side facing your head. Neutralizer Discs take a different approach: they harmonise the field without blocking the signal, so you get protection without the battery drain or dropped calls.

The Problem

Your phone is your #1 source of daily EMF exposure

Most of us hold a powerful microwave transmitter against our head for hours every day. When you’re looking for the best EMF protection for phone use, you need something that works continuously — without making the phone itself worse.

Constant proximity

Average Australian phone use is 5+ hours per day, often pressed to the ear or kept in a pocket.

4G, 5G & Wi-Fi layered

Your phone emits multiple overlapping EMF signatures simultaneously, all in close range.

Common symptoms

Many users report headaches, "hot ear", tiredness and disrupted sleep after long phone sessions.

The Solution

Aulterra Neutralizer Discs — the best EMF protection for your phone

One tiny disc. Peel, stick, forget. Protection that works 24/7 without touching your signal, battery life, or phone case.

How It Works

Harmonise, don’t block — the smarter EMF protection for phones

Shielding products block your signal and force your phone to work harder (which increases radiation output). Aulterra discs take the opposite approach.

Re-organise the signal

A patented blend of paramagnetic minerals re-orders the chaotic phone EMF field into a more coherent pattern.

Support your biology

Coherent fields are less disruptive to biological systems — fewer headaches, less "hot ear", better focus during long calls.

Keep full signal & 5G

Nothing is shielded or blocked. Your phone runs normally with full reception and normal battery life.

Independent Lab Evidence

The only phone EMF protection backed by magnetometer testing

Real, measurable, third-party data — not marketing fluff.
