Why ShieldGuard?
Engineering-grade protection once reserved for hospitals and data centres โ now built for North American homes.
HEPA+ UV-C Purifier
Room isolation with closed-circuit filtration and enclosed 265 nm UV-C โ 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.
Professional software + apps
A2LA Launchpad (lab accreditation OS) & DecoyShield โ plus health, finance & entertainment apps.
Particle Size โ Real Test Data
Independent measurements from 0.3 ยตm (MPPS) to 10 ยตm โ 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 ยตm to 10 ยตm โ the same range in our HEPA+ efficiency reports. The Temptop monitor (right) confirms "Good" air quality at PM2.5 2.3 ยตg/mยณ.
Room Isolation โ Not Just Another Purifier
Developed during COVID to isolate one room from the rest of the building โ not whole-home HVAC. One floor inlet open, others sealed, door closed โ clean air returns to the same room with positive pressure.
Air is drawn from a single open floor inlet (all others sealed). It passes through the replaceable cartridge (pre-filter โ charcoal โ HEPA H14 โ MERV17 barrier), then the fan drives air into the enclosed 265 nm UV-C chamber where remaining viral DNA/RNA is disrupted. Clean, UV-treated air returns to the same room through the outlet โ creating positive pressure at the closed door that blocks contaminated air from other rooms and floors.
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 โ 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 โ 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 โ critical in Canada and the western United States.
Allergy & Asthma
HEPA+ filtration at 0.3 ยตm MPPS captures pollen, mold spores, and allergens that trigger attacks.
Bedroom / Home Office
Turn one room into a controlled-air zone โ ideal for remote work, post-surgical recovery, or restorative sleep.
