About Us
Welcome to SHIELDGUARD INC – Protecting What Matters Most.
Founded in Ancaster, Ontario, SHIELDGUARD INC was born from the vision and determination of Clauzer Dziedziensky. Our company exists to bring the same advanced protection once reserved for corporate and hospital environments directly into Canadian homes.
Clauzer holds a technical background in Telecommunications (with a focus on engineering) and has more than 20 years of international experience with industry leaders such as Philips, Ericsson, FORE Systems, and Marconi PLC. He later built a successful solo career, creating a patented “Safe Room” for data centres that earned UL certification for fire, smoke, IP66, and electromagnetic field protection. He designed and built his own testing laboratory from the ground up, implementing a complete Quality Management System for accreditation and conducting both destructive and non-destructive testing.
After professional challenges brought him to Canada, Clauzer settled in the automotive industry (powder metallurgy). The COVID-19 pandemic, however, gave him a powerful new purpose: to protect Canadian families, especially seniors, with safe, accessible technology.
Our first product is the SHIELDGUARD INC HEPA Air Purifier with fully enclosed 265 nm UV-C, a compact, quiet system engineered to help keep your home’s air cleaner and fresher while meeting the highest Canadian safety standards.
And this is just the beginning. Soon, SHIELDGUARD INC will also launch a line of residential bunkers inspired by the same proven corporate Safe Room technology, delivering advanced protection against fire, smoke, and environmental threats right inside your home.
Proudly 100% Canadian. Designed, engineered, and manufactured right here in Ancaster, Ontario, every SHIELDGUARD INC product supports local jobs, drives homegrown innovation, reduces our dependence on imports, and strengthens Canada’s economy one protected household at a time.
Our mission is simple yet powerful: to deliver intelligent protection technology that keeps your family safe and healthy without the hassle. Every product is created with the same technical rigour, passion, and respect for standards that have defined Clauzer’s entire career.
Because clean air and real protection aren’t luxuries. They’re Canadian necessities. And we’re here to deliver them, one secure home at a time.
