Why ShieldGuard?
Engineering-grade protection once reserved for hospitals and data centres — now built for North American homes.
HEPA+ UV-C Purifier
Room isolation with closed-circuit filtration and enclosed 265 nm UV-C — one inlet open, positive pressure, clean air stays in YOUR room.
Modular Bunkers
UL-inspired safe room technology adapted for Canadian & U.S. residential basements.
Canadian iOS Apps
AllergyGuard, MoneyGuard, DecoyShield, LottoInsight AI & Lotto US 250 — privacy-first tools.
Particle Size — Real Test Data
Independent measurements from 0.3 µm (MPPS) to 10 µm — the most penetrating particle sizes that HEPA filters must stop. See the live counters in action.
The JLDG particle counter (left) measures particles from 0.3 µm to 10 µm — the same range in our HEPA+ efficiency reports. The Temptop monitor (right) confirms "Good" air quality at PM2.5 2.3 µg/m³.
Room Isolation — Not Just Another Purifier
Developed during COVID to isolate an apartment or room from the rest of the building. One inlet open, others sealed, door closed — clean air returns to the same room with positive pressure.
Unlike portable purifiers that pull room air, filter it, and release it back while contaminated air from other rooms and outdoors keeps entering through HVAC, ShieldGuard seals all inlets except one, processes air through every stage of the block diagram (pre-filter → charcoal → HEPA H14 → UV chamber → fan → MERV17), and returns clean air to the same room — creating positive pressure at the closed door that blocks pathogens from the rest of the building.
Who Needs ShieldGuard?
Engineered during COVID for one precise mission: isolate a room from the rest of the building.
Senior Care Homes
Isolate a sick resident's room from the rest of the building. During COVID, shared HVAC systems spread contaminated air across floors — sometimes 5+ deaths per week in a single facility across North America.
Apartments & Condos
One inlet open, others sealed, door closed. Clean air stays in YOUR unit — droplets from a neighbour or another floor cannot infiltrate.
Families with Vulnerable Members
Protect seniors, immunocompromised individuals, and allergy sufferers by creating a filtered, UV-C treated air barrier in a dedicated room.
Wildfire Smoke
Closed circuit + positive pressure reduces infiltration of fine particulates (PM2.5) from outdoors — critical in Canada and the western United States.
Allergy & Asthma
HEPA+ filtration at 0.3 µm MPPS captures pollen, mold spores, and allergens that trigger attacks.
Bedroom / Home Office
Turn one room into a controlled-air zone — ideal for remote work, post-surgical recovery, or restorative sleep.
