SENIOR CARE & HEALTHCARE
Healthier Residents. Steadier Operations.
Respiratory illness in senior living doesn’t just affect residents — it disrupts staffing, supply chains, and daily operations across the entire facility. UV-C air disinfection addresses the problem at the source.
THE OPERATIONAL COST OF ILLNESS
When One Resident Gets Sick, the Whole Building Feels It
When respiratory illness spreads through a senior living community, daily operations shift rapidly from routine care to crisis management. Infection prevention and indoor air quality improvements are increasingly viewed as a core operational strategy — not a discretionary upgrade.
Staff Absences
Care teams spend more time on monitoring and isolation protocols, driving overtime and burnout.
Supply Consumption
Oxygen, PPE, and testing materials are consumed more quickly during outbreaks.
Hospital Transfers
Each transfer requires coordination, documentation, family communication, and follow-up care planning.
Routine Disruption
Dining, activities, and daily services are interrupted — affecting resident wellbeing and family confidence.

FIELD EVIDENCE
Field-Tested. University-Verified.
Light Progress partnered with researchers from Purdue University’s Lyles School of Civil and Construction Engineering to evaluate upper-room germicidal UV disinfection at Cardigan Ridge, a 118-unit senior living community in Minneapolis.
11 upper-room GUV units were installed in dining spaces, the library, fitness rooms, and gathering areas. The existing HVAC infrastructure remained completely unchanged. All commissioning followed NALMCO’s internationally recognized GUV certification protocols. The project aligned with ASHRAE Standard 241 for Equivalent Clean Air delivery without mechanical upgrades.

What the Pilot Answered
No HVAC Replacement Required
UV-C disinfection was added as a clean-air layer on top of existing ventilation — no mechanical upgrades, no capital disruption.
Minimal Disruption to Residents
Systems were commissioned and validated following NALMCO protocols with no interruption to daily operations or resident routines.
Credible Evidence Generated
Independent university researchers tracked CO₂ levels, HVAC data, core IAQ parameters, and infection incidence across five comparable facilities.
FEATURED PRODUCTS
UV-C Systems for Senior Living Environments
Solutions for in-room air disinfection in shared spaces and HVAC-integrated disinfection for centralized systems — all safe for occupied environments.
IN-ROOM
UV-FAN Series
Professional air purifiers with internal UV-C chamber and silent built-in fan. Safe for occupied spaces 24 hours a day. Wall mount or floor stand. Multiple sizes available for any room. Independent lab tested.
UPPER-ROOM GUV
UV-FLOW-WL
Wall-mounted upper-room GUV unit. The exact product deployed at Cardigan Ridge. Proprietary louvres direct UV-C energy upward — away from occupants. Operates silently 24/7. ASHRAE 241 aligned. Covers 150–376 sq ft per unit.
UPPER-ROOM GUV
UV-FLOW-CL
Ceiling-suspended upper-room GUV unit for larger shared spaces — dining rooms, atriums, activity halls. Same proven UV-FLOW technology as the wall mount. Covers up to 860 sq ft per unit. Operates silently in occupied spaces 24/7.
IN-DUCT
UV-DUCT-FL
Flanged in-duct UV-C unit installed directly from the outside duct wall — no duct cutting required. Compact stainless steel construction. Embedded power supply with visual lamp alarms. Ideal for retrofit into HVAC systems serving shared spaces.
