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.

Products and Services

1 - SHIELDGUARD HEPA AIR PURIFIER WITH PATHOGEN INACTIVATOR

Three Products in One:

• A HEPA+ Air Filter
• A Pathogen Inactivator with ultraviolet radiation
• A Chamber to place your personal belongings for sanitization

SHIELDGUARD INC introduces the ultimate air filter designed to safeguard your home and family. This advanced air filter utilizes state-of-the-art HEPA technology, effectively capturing microscopic particles and contaminants from the air drawn through your floor vents. It creates an airtight, positive pressure environment within your home, ensuring that only clean, filtered air circulates while preventing the infiltration of harmful pollutants. Engineered for maximum efficiency and reliability, this system provides a healthier living space for you and your loved ones.

NOTE: This is a professional performance product designed for residential applications.

A HEPA+ AIR FILTER

Our mobile air filter utilizes HEPA+ technology. This innovative device ensures clean and purified air in your home, providing you and your family with a healthier living environment. Breathe easy knowing that harmful particles are being captured.

The heart of the air filter is our cartridge, specially assembled by SHIELDGUARD INC, which includes an activated carbon pre-filter film, HEPA filters in series, and a final MERV17 filtering material film. This set, assembled into a single cartridge, is easy to install and/or replace, every 12 months under normal use, or every 6 months under heavy use, to maintain adequate air filtration levels comparable to clean rooms or surgical operating rooms according to ISO 14644-1.

HEPA is a type of pleated mechanical air filter (High Efficiency Particulate Air). It can theoretically remove at least 99% of dust, pollen, mould, bacteria, and airborne particles sized 0.3 microns (µm), the most penetrating particle size (MPPS). Particles larger or smaller are trapped with even higher efficiency.

Efficiency in Filtration

Your independent test results demonstrate exceptional real-world performance that surpasses typical HEPA expectations:

True HEPA standards require a minimum 99% efficiency at the most penetrating 0.3 µm size (MPPS) under controlled lab conditions. Your results show near-complete elimination across all tested sizes, with only trace passage at 0.3–0.5 µm — meaning dramatically reduced airborne pollutants, allergens, mould spores, and fine particulates in everyday home use. This outperforms many consumer “HEPA-type” products (often 85–95% at best) and aligns closely with or exceeds medical-grade filtration, translating to significantly cleaner indoor air for families, seniors, and allergy sufferers.

Filter Replacement Frequency

• Normal Use (8–12 hours/day): 12 months
• Heavy Use (>12 hours/day): 6 months

PATHOGEN INACTIVATOR & SANITIZING CHAMBER

In the upper chamber, filtered air passes at low speed and receives a controlled dose of UV-C (265 nm) to help inactivate potential pathogens that may have passed through mechanical filtration. The chamber also serves as a sanitizing space for personal items, place objects inside, close the lid, and expose for a minimum of 2 minutes for effective UV-C dosage.

ULTRAVIOLET

UV-C radiation (peak at 265 nm) has a long history of use in disinfection, from water treatment in the 1930s to modern healthcare and air systems. It damages the DNA/RNA of bacteria and viruses, preventing replication. Studies confirm 265 nm is highly effective against pathogens, including coronaviruses, while remaining safe when fully enclosed (as in our design). Always follow safety guidelines, UV-C can harm skin/eyes if exposed directly.

DEVICE OVERVIEW, SET-UP AND USE

The product is designed in two parts: lower (cartridge with HEPA+ filters and fan); upper (chamber with 265 nm UV-C emitters).

Recommended Devices for Sanitization

Quickly sanitize: PPE (masks/respirators), cell phones, tablets, laptops, jewellery, glasses, keys, watches, badges, walkie-talkies, and more. Build the habit of sanitizing items that may carry pathogens from public spaces, especially helpful for vulnerable family members.

Why SHIELDGUARD FILTER is Different from Regular Air Purifiers

Closed Circuit + Positive Pressure – True Whole-Home Protection

Unlike traditional air purifiers that only clean the air in their immediate vicinity.

Traditional Air Purifiers (what most people buy):

• Operate in an open-loop system: they pull in room air from one side, filter it, and blow it back into the same room.
• Fresh (potentially contaminated) air continues to enter the home through windows, doors, vents, leaks, and HVAC returns.
• The filtered air mixes constantly with new unfiltered air → efficiency drops quickly (often only 20–40% of the room air is actually cleaned over time).
• They do not prevent external pollutants from entering the home.

SHIELDGUARD FILTER – Closed Circuit + Positive Pressure Concept

• Captures air directly at the floor vents / return intakes of the central forced-air system (furnace / air conditioner).
• Filters and inactivates pathogens before the air is distributed through the ductwork.
• Releases cleaner, filtered air back into the home, creating positive pressure in the conditioned space.
• This positive pressure gently pushes air out through any small leaks (windows, doors, exhausts), preventing unfiltered outside air from infiltrating.
• The filtered air circulates through the entire central HVAC system → progressively reaches every room in the house (just like if the filter was installed directly in the main unit in the basement).
• Over time (depending on runtime), the home approaches 100% filtered air circulation — a true whole-home solution.

Key Advantages of SHIELDGUARD FILTER Approach

• Isolates the indoor environment from external contamination (pollen, dust, wildfire smoke, urban pollutants, viruses brought in from outside).
• No mixing of filtered and unfiltered air — the efficiency remains high even after hours of operation.
• Works with your existing central HVAC system — no need for standalone units in every room.
• Creates a healthier, more consistent air quality throughout the entire home, not just one area.

2 - Bunker Residential Modular: Smart Protection in Uncertain Times

In today's increasingly unpredictable world — marked by escalating geopolitical tensions (such as ongoing conflicts in Ukraine and the Middle East), intensifying climate extremes (wildfires, floods, and severe storms across Canada), lingering pandemic risks, and economic instability — safeguarding your family and home has never been more essential. Demand for residential bunkers and safe rooms has surged globally and in Canada, with the bunker market projected to grow from US$137 million in 2023 to US$175 million by 2030 (BlueWeave Consulting), and searches for "homes with bunkers" up dramatically in recent years (Realtor.com data). Modular residential bunkers offer a practical, innovative solution: a secure, customizable refuge that protects what matters most while adding real value to your property.

What Is a Modular Residential Bunker?

A modular residential bunker is a prefabricated structure built from high-strength metal panels for walls, ceiling, floor, and door. Designed for easy installation in your home (often discreetly in the basement), it can be fully customized to your needs. Beyond emergency shelter, it doubles as a guest room, music studio, wine cellar, or secure storage space. Its modular design ensures fast, efficient installation — weeks instead of months — making it a smart choice for homeowners seeking peace of mind without disrupting their lifestyle.

Key Features and Benefits

• Durability and Strength: Engineered metal panels withstand extreme conditions, high winds, earthquakes, forced entry attempts — providing reliable protection in an era of rising natural disasters and civil unrest.
• Sustainability: Modular construction minimizes material waste and uses recyclable resources, aligning with Canada's growing focus on eco-friendly building practices.
• Full Customization: Tailor everything from security monitoring, advanced ventilation, backup power, and survival systems to match your family's unique requirements.
• Superior Cost-Effectiveness: Compared to traditional custom builds, modular bunkers save over 60% in time and resources — a smart investment in uncertain times.
• Expert Support: Specialized providers offer full consultation, precise execution, and ongoing support, ensuring your project meets the highest safety standards.

Types of Protection Offered

Here's a clear comparison of the threats addressed:

Additional Benefits

Beyond core security, a modular bunker adds lasting value to your life and property:

• Versatility: Seamlessly doubles as a guest suite, home office, wine cellar, or valuables storage — all hidden in your basement layout.
• Significant Property Value Increase: In Canada, features like bunkers or safe rooms can boost resale value by 5-26% (or more in luxury markets in Toronto, Vancouver, and Calgary), according to real estate trends and reports from Realtor.com and industry analyses. The initial cost is often recouped (and exceeded) through higher resale premiums, especially as demand for "resilient" and "secure" homes grows amid global uncertainties. In many cases, the bunker can be included in residential financing.
• Aesthetic Integration: Blends perfectly with your home's design — no visible disruption.
• Rapid Installation: Prefabricated components allow completion in weeks, letting you prepare quickly.

For Investors

A Message to Investors

Dear Investor,

Imagine owning a piece of two breakthrough Canadian inventions that solve real, everyday problems, clean air and home protection, in markets that are growing rapidly and have almost zero direct competition in Canada.

I am Clauzer Dziedziensky, founder and CEO of SHIELDGUARD INC, and I’m inviting you to be part of something special.

Two Exclusive, Patented Products – 100% Designed & Built in Canada

1. SHIELDGUARD HEPA Air Filter with Fully Enclosed 265 nm UV-C
   The first and only system of its kind in Canada that combines true-HEPA filtration with UV-C technology completely sealed inside the unit (zero UV leakage). Engineered for families, seniors and homes, it delivers supplemental air purification while meeting every Canadian safety standard. No chemicals, ultra-quiet, compact, and ready for direct-to-consumer sales.
2. SHIELDGUARD Residential Bunker
   The residential version of my internationally successful corporate “Safe Room” (already patented and UL-certified in my name). This is the first bunker designed specifically for Canadian homes, protection against fire, smoke, extreme weather, and environmental threats. Compact, affordable, and installable in basements or new builds. A game-changer in an era of increasing climate events and safety concerns.

Both products are patented or patent-pending in Canada, giving us true exclusivity and strong barriers to entry. No one else offers this exact combination of proven technology, full regulatory compliance, and local manufacturing.

Why This Is an Exceptional Opportunity

• Niche markets with explosive demand: Post-pandemic air quality awareness + growing home-safety and climate resilience needs. The Canadian air purifier market is growing at ~6–8% CAGR (projected to reach CAD 1.2–1.3 billion by 2033); residential shelters remain virtually untapped here amid rising geopolitical and weather risks.
• High-margin, asset-light model: Air Filter: Direct-to-consumer via Shopify, Amazon Canada, and our website. Bunkers: Sales through home builders and real estate teams. No expensive retail stores or large sales forces needed. Excellent margins from Ontario manufacturing control.
• Proudly 100% Canadian: Creates local jobs, qualifies for SR&ED, IRAP, and provincial incentives, and appeals to buyers who prefer homegrown over imports.
• Modest investment, outsized returns: Fund certification, initial runs, and marketing with relatively small capital. Scalable quickly, ship within months, low overhead for national/international expansion.
• Multiple revenue streams: Product sales + replacement filters + bunker accessories + B2B (seniors’ residences, builders, small businesses).

These are proprietary, mission-driven Canadian inventions from an engineer who has already patented, certified (UL), and commercialized complex safety products. I built accredited labs from scratch and navigated global standards, now ready to scale with the right partners.

If you believe in Canadian innovation, high-margin products, and protecting families while building wealth, let’s talk.
