To Our Valued Vapvana Community,
At Vapvana, our mission is to deliver the purest and most powerful vaping experience possible.
This commitment goes beyond performance and flavor - it is rooted in a foundation of rigorous engineering, quality materials, and, most importantly, user safety and transparency.
Recently, a detailed and thoughtful review of our new "The Natural" vaporizer by Lee from TableTopBong sparked an important conversation in the community about electromagnetic fields (EMF).
We want to thank Lee for his thoroughness and for bringing this topic to the forefront. We see this as a valuable opportunity to share the depth of our own research and to address your questions head-on.
Let’s dive in.
Understanding the EMF Readings
In his review, Lee used a TRIFIELD meter and accurately measured pulsed magnetic fields from the Natural's PID controller, with peaks around ~9 milligauss (mG) when the meter was held directly against the unit.
It is completely understandable to see these numbers and have questions. So, what do they mean in the context of safety?
To answer this, we must look at the established international safety standards and the specific nature of the exposure.
Official Safety Standards vs. Measured Emissions
The leading global authority on non-ionizing radiation protection is the International Commission on Non-Ionizing Radiation Protection (ICNIRP).
Their guidelines are designed with significant safety margins to protect against all known adverse health effects from acute exposure, primarily nerve stimulation[1].
To put these numbers into context, the ICNIRP sets the general public reference level at 2,000 mG [1].
The peak emissions measured at the source of the PID were just ~9 mG. This means The Natural PID operates at a level that is more than 222 times lower than the established international safety guideline.
Furthermore, magnetic fields from a small source like this decay rapidly with distance. At a typical user distance of 1-3 feet, the actual exposure is significantly lower than the peak measured at the source.
Conclusion: The Natural PID & our other kits operates far below the established international safety guidelines for preventing acute health effects.
The "3 mG Threshold" - A Matter of Context
So where does the "3 mG" concern level often discussed online come from?
This informal threshold is derived from the International Agency for Research on Cancer (IARC) classifying ELF magnetic fields as "Group 2B: Possibly carcinogenic to humans"[2].
It’s important to note this is the same classification given to common items like coffee and pickled vegetables, indicating the evidence is limited and not conclusive[3].
Crucially, this classification was based on a statistical association found in some epidemiological studies between childhood leukemia and chronic, 24/7 residential exposure to average fields exceeding 3-4 mG[2].
The usage of The Natural & PID vaporizer is fundamentally different from this context:
User Population: Users are adults, not the specific child population group from the studies.
Exposure Pattern: Use is intermittent (a few minutes per session), not chronic (near-continuous for years).
Exposure Level: The time-averaged exposure for a user is extremely low and well below the 3-4 mG average level of concern from those studies.
While we respect every individual's approach to safety, it is scientifically inaccurate to apply a chronic, 24/7 exposure metric for children to the intermittent use of an appliance by an adult.
Our Commitment to Prudent Avoidance and Future Innovation
While The Natural, and our other vape kits, are engineered to be safe and compliant with all relevant international standards, we believe in empowering our users.
We hear the community's interest in the principle of "prudent avoidance" - reducing exposures where possible, even when they are already well below established limits.
Based on these recent developments, we have started researching ways to offer an optional EMF shield for our PIDs.
This is now an active project for our engineering team. Our goal is to investigate solutions using scientifically-validated materials to offer a significant reduction in emissions for those who want it.
We are committed to transparency and will update you when we have more info available. To stay informed, please subscribe to our newsletter or follow our social media channels for the latest news on this initiative.
Our Promise To You
Your trust is our most important asset. We will always be transparent, lead with science, and listen to our community.
The Natural was designed to be a pinnacle of performance and flavor, and we will ensure it continues to be a benchmark for safety and thoughtful engineering.
Thank you for being part of the Vapvana family and for pushing us to be our best.
Happy Vaping,
Cal & The Vapvana Team

This factsheet from the International Commission on Non-Ionizing Radiation Protection summarizes their official guidelines. It establishes the 200 µT (2,000 mG) reference level for the general public and explains it is based on preventing acute nerve stimulation, stating evidence for long-term effects is too weak to serve as a basis for guidelines.
-
This is the foundational report from the International Agency for Research on Cancer that classified ELF magnetic fields as "Group 2B: Possibly carcinogenic to humans." The classification is based on limited epidemiological evidence for childhood leukemia with chronic average exposures above 0.3-0.4 µT (3-4 mG).

This official list from IARC provides context for the Group 2B classification, showing it includes a wide array of agents where the evidence of carcinogenicity is not conclusive, such as coffee, pickled vegetables, and gasoline engine exhaust.
