When shopping for EMF protection, you’ll encounter two fundamentally different categories of products: active and passive protection devices. Understanding the distinction between these approaches is crucial for making informed decisions about EMF protection strategies.
Defining Active vs. Passive EMF Protection
Passive EMF Protection
The majority of EMF protection devices on the market could be considered “passive” devices, which means they don’t use electricity to amplify a signal, making them more subtle and inert aspects of your environment [1].
Passive devices include:
- EMF stickers and chips
- Crystals and minerals (Shungite, Black Tourmaline, etc.)
- Pendants and wearable jewelry
- Non-powered harmonizers
- Pyramids and decorative objects
EMF protection stickers are marketed as subtle tools to help shield your body from electromagnetic fields, with embedded frequency matrices that passively interact with surrounding fields to bring greater energetic coherence and reduce disruption [2].
Active EMF Protection
Active EMF Protection Technology uses power to mitigate EMF at a cell level, using powerful fields instead of weak passive fields that may transmute energies or EM fields [3].
Blushield is a revolutionary form of EMF protection that produces coherent frequencies within the human responsive range based on nature-mimicking mathematical algorithms, emitting frequencies using the same power sources as manmade devices to create active, powerful fields [4].
Active devices are powered and generate their own fields to compete with or override harmful EMF.
How Passive Protection Claims to Work
The Harmonizing Concept
EMF stickers and pendants are sold as a way to either neutralize or minimize the effects of EMF radiation, with makers often saying they “harmonize” or “reconfigure” EMF waves to make them less harmful, using terms like “negative ions” or “scalar energy” to explain how they change EMF behavior [5].
At the heart of many EMF protection stickers is the concept of resonance, with stickers designed to emit a specific frequency that supposedly resonates with harmful EMFs, neutralizing their effects by matching the frequency of the EMFs to disrupt and mitigate potential harm [6].
Materials Used in Passive Devices
The materials used in these stickers vary widely, but common components include crystals, metals, and other conductive materials, with some stickers claiming to use proprietary blends of minerals and elements that are said to have unique properties capable of interacting with EMFs [6].
An EMF Protection Pendant is a pendant made out of either a single mineral or multiple minerals that form a natural paramagnetic field around them that alter man-made EMFs and change them into a more natural less harmful form [7].
How Active Protection Works
Power and Signal Strength
Active protection is essentially “loud” enough to compete against the biologically incoherent non-native EMF fields, vastly outperforming protective devices with weak, passive fields that don’t use a power source such as stickers, pyramids and pendants [4].
Instead of attempting to block EMFs, which is ineffective or suboptimal for various reasons, Blushield essentially overpowers non-native EMFs with resonant frequencies and becomes the dominant carrier signal in the environment [8].
Constant Variation
Many popular devices only produce single frequencies, like Schumann resonance devices that usually run at a constant 7.83 Hz, or a repeated combination of frequencies like Solfeggio, which may deliver some benefits at first, but after some time, the body will stop responding positively to these repetitive frequencies because nature itself is constantly varying [4].
In contrast, Blushield emits scalar waveforms that never stimulate your body twice with the same combination of frequencies at the same amplitude, mimicking nature but much more powerfully [4].
The Effectiveness Question
Passive Devices: Limited Evidence
A main concern with many EMF products is the absence of solid, independent testing, with most stickers and pendants not backed by third-party lab results or research proving they actually reduce or block EMF radiation [5].
There is yet very little evidence to support that EMF Protection stickers work, and they could offer some short term relief from EMF, but don’t assume that you don’t need to take other safety precautions [9].
Pendants and stickers thrive on ease—slap it on, wear it, done—but no measurable RF drop means their EMF radiation risks relief is more hope than reality, offering style over substance for those chasing tangible results [10].
The Blocking Misconception
EMF radiation can only be blocked or deflected by certain materials, like metals, that absorb or reflect the radiation, and since most EMF stickers and pendants are made from non-metallic materials, they aren’t built to block radiation in this way, instead claiming to “modify” the radiation itself [5].
Harmonizers, whether they’re shaped like colored glass flying saucers or round pieces of wood wrapped with copper threads, whether they’re Q-links, scalar energy devices, crystals, Shungite necklaces, stickers, chips or shields—do not stop EMF radiation and there is zero proof that they are protecting you from the harmful health effects of EMF [11].
Active Devices: Different Testing Approach
Since Blushield relies on scalar fields for its effectiveness, and not the measurable electromagnetic fields, different tests are required to show Blushield’s effectiveness, and to get straight to the point of why we use these protection devices in the first place, Blushield testing has focused on the effects of this technology on humans and animals [12].
Power Source and Energy Requirements
Passive: No Power Needed
Passive devices require no electricity, batteries, or external power source. They are:
- Always “on” by nature
- Maintenance-free
- Portable and lightweight
- Simple to use
Once applied, frequency matrices passively interact with surrounding fields to bring greater energetic coherence and reduce disruption [2].
Active: Requires Power
Blushield uses microprocessor technology to emit the field, which is both effective and uses very little power [13]. Active devices need:
- Electrical outlet (for home units)
- Batteries (for portable units)
- Regular charging or power connection
So many products that emit an actual electromagnetic frequency use coils or the equivalent of a coil, which are both costly and use a lot of power, reducing battery life and causing interference with other electronic devices, and coils also cause stress on the body [13].
Coverage Area and Protection Range
Passive Devices: Limited Range
Just a chunk of Shungite sitting on a table or putting a Shungite pendant around your neck won’t do much of anything—Shungite only blocks EMF under the small area it covers [11].
Passive devices typically only affect:
- The immediate area they cover
- The person wearing them (for jewelry)
- A very small radius around the object
Active Devices: Broader Coverage
Blushield home and office models plug into a standard powerpoint and use mains power to broadcast a field strong enough to effectively compete against the effects of EMF in your environment, with this strong field required for your body to initially entrain to the Blushield frequencies via sympathetic resonance [4].
Active devices can cover entire homes, offices, or significant areas depending on the model strength.
Scientific Backing and Research
The Crystal and Mineral Controversy
Dr. Klinghardt talks about a 5-year study of “Crystal Containing Devices” that were thought to help clean up dirty electricity around chickens, where at first it seemed to help but then the chickens ended up dying twice as early as other chickens that were not protected [11].
Dr. Klinghardt basically advises that it’s better to “feel” the negative effects of EMF radiation instead of depending on products that could “mask” the energy with harmonizing energy that may make you feel better in the short run, but doesn’t actually do anything to stop the detrimental effect of electromagnetic fields [11].
Placebo Effect Considerations
EMF protection products that claim to harmonize energy “give the illusion of safety,” according to Dr. Klinghardt [11].
The downside to human testing is the slight potential for psychosomatic factors to come into play, such as someone being tested who believes the Blushield will work, and their optimism improves their physical results or their perception of their symptoms [3].
This is why animal studies can be particularly valuable—they eliminate placebo effects entirely.

What the Experts Say
Physicians for Safe Technology have signed an appeal to the World Health Organization advocating for precautionary health regulations and warnings over mobile phone radiation [9].
The consensus from many EMF experts is that avoidance and distance from EMF sources remain the most scientifically validated protection strategies, regardless of which type of protection device you choose.
Making Your Decision
When Passive Might Make Sense
Anyone regularly exposed to modern technology can benefit from EMF protection devices, and an effective device should provide broad-spectrum protection or be available in configurations designed for different devices and environments [14].
Passive devices might be worth trying if you:
- Want a low-cost entry point
- Prefer something with zero maintenance
- Find comfort in wearing protective jewelry
- Are willing to experiment with subjective benefits
- Want something that’s simple and portable
When Active Might Be Better
Blushield’s Active EMF Protection Technology is an active solution for EMF which is one form of incoherence within our environment, and passive devices can be stickers, pendants or pyramids, all of which seem to be far less effective at bringing coherence to the body and environment [3].
Active devices might be preferable if you:
- Want broader whole-home/office coverage
- Prefer technology based on measurable power output
- Are looking for products with biological testing
- Need protection across multiple EMF sources
- Want devices that don’t interfere with electronics
The Combined Approach
If you want broader coverage, pairing stickers with EMF protection for phone or other devices can offer more complete support [2].
Some people use both approaches:
- Active device for whole-home protection
- Traditional shielding for specific high-exposure situations
- Distance and avoidance as primary strategy
- Passive devices as supplementary support
Critical Considerations
If a product starts using complex terms or makes vague claims about “neutralizing” EMFs in ways that don’t make sense or can’t be easily verified, it’s a good idea to approach it with caution [5].
We recommend that you always take the time to understand exactly what a product is supposed to do before you buy into its promises [5].
Key questions to ask:
- What specific mechanism does this product use?
- Is there independent testing available?
- Can the effectiveness be measured or verified?
- What does the scientific community say about this approach?
- Are testimonials the only “proof” offered?
The Bottom Line
The distinction between active and passive EMF protection comes down to power, coverage, and evidence:
Passive devices are unpowered, subtle tools that claim to harmonize or neutralize EMF through materials like crystals or metals, but generally lack strong scientific validation and offer very limited coverage.
Active devices use power to generate competing fields that aim to override harmful EMF, offer broader coverage, and focus on biological testing rather than field measurement.
Unless you minimise exposure to wireless radiation signals, you have no real long term solution [9]. Regardless of which type of protection you choose, experts generally agree that the most effective EMF protection strategy includes:
- Distance from EMF sources
- Avoidance when possible (turning off WiFi, using airplane mode)
- Traditional shielding for specific high-exposure situations
- Protection devices (active or passive) as supplementary support
Understanding the difference between active and passive EMF protection empowers you to make choices aligned with your needs, budget, and understanding of the available evidence.
