Engineering-grade accuracy
Real measurements, real outcomes — never guesswork. Every residential, commercial, and industrial assessment is grounded in field readings you can act on with confidence.
Our Story
Making the invisible, visible.
Since 2016, emfMax has led EMF awareness, assessment, and mitigation — bringing engineering precision and a human voice to an industry most people have never been taught to question. We protect both human wellbeing and operational integrity — homes, families, and industrial facilities where EMI disrupts equipment and security.
The Founder’s Journey
A founder’s encounter. A mission that followed.
emfMax began as Choizya in 2016, founded by Max Chua after a personal encounter with the health consequences of long-term electromagnetic exposure. What started as a private search for answers quickly became a professional calling: translating the physics of radio frequencies, dirty electricity, and magnetic fields into something a family — or an operations team — could actually act on.
From a single Singapore home visit to thousands of residential, commercial, and industrial assessments worldwide, Max has spent 10+ years building one of the region’s most practised EMF safety practices — one informed by engineering-grade meters, real-world case studies, and tight relationships with shielding manufacturers and health professionals. Today the work spans tailored solutions to shield homes, workplaces, and individuals, and industrial facilities where EMI disrupts operations.
In 2024, Choizya evolved into emfMax. The new name reflects a sharper promise: maximum clarity in detection, maximum rigour in assessment, maximum effectiveness in mitigation. Same founder, same standards, modernised for a 5G world.
Two audiences, one mission. We protect human wellbeing and operational integrity — from bedroom EMF exposure to mission-critical RF interference in commercial environments.
The Rebrand
From Choizya to emfMax.
Same founder. Same 10+ years of expertise. A sharper name and a clearer promise — one practice serving two audiences: health protection for homes, families, and EHS-sensitive individuals, and industrial EMI protection for commercial clients where electromagnetic interference can affect equipment performance, operational reliability, and data security.
Health & safety certified
Methodology aligned to recognised EMF safety frameworks. We work alongside doctors, naturopaths, workplace Health & Safety teams, and industrial operations leads across the region.
Solutions you’ll use
EMF shielding materials, dirty-electricity filters, and interference-mitigation products engineered for daily life inside real homes, workplaces, and industrial facilities — not just lab benches.
Our Mission
Homes that thrive in health. Industries that run seamlessly and securely.
We exist to give families and organisations a clear, unhyped path to EMF-safer environments — protecting human wellbeing at home, and improving EMI performance for clients whose equipment, data security, and operations depend on it running seamlessly and securely. Detect what’s there. Assess what it means. Mitigate what matters. Then get back to living — or running the business.
