Your Building Has
Lungs.
The HVAC system is the building's respiratory system — it inhales, filters and breathes air into every occupied space. ORRIS now integrates the EnviroBiotics E-Biotic Pro probiotic treatment directly into its HVAC units, establishing a living biological defense layer that combats Sick Building Syndrome at the source, 24 hours a day.
Sick Building Syndrome —
A Hidden Epidemic
The WHO estimates that up to 30% of office buildings worldwide suffer from Sick Building Syndrome (SBS) — a cluster of symptoms directly linked to poor indoor air quality. Contaminated HVAC systems are the primary vector, recirculating biofilm-laden air throughout every occupied floor, every hour of the working day.
Biofilm buildup on coils and duct surfaces doesn't just degrade air quality — it forces the HVAC system to work harder, increases energy consumption, accelerates component wear and shortens system lifespan.
COMMON SBS SYMPTOMS
Biofilm in Ducts & Coils
Over time, moisture and organic particles accumulate inside HVAC ductwork and on coils, forming a thick biofilm layer that harbors mold, bacteria and pathogens — circulated continuously into occupied spaces.
Poor Ventilation Design
Recirculated air without adequate fresh-air exchange concentrates CO₂, VOCs and airborne microorganisms, far exceeding safe indoor thresholds.
High Humidity Zones
Moisture-rich environments inside air handling units create ideal conditions for mold spore growth, which are then distributed through the entire building.
Chemical Disinfectants
Traditional disinfectants kill on contact but evaporate within minutes, leaving surfaces unprotected until the next application cycle.
Competitive Exclusion
Environmental probiotics don't kill — they outcompete. By establishing a dominant colony of beneficial Bacillus bacteria on every surface, harmful microorganisms are deprived of the organic nutrients they need to survive and reproduce.
Disperse
The E-Biotic Pro unit, installed directly in the HVAC ductwork, releases a calibrated mist of Bacillus probiotics every 30 minutes — automatically, silently, with no manual interaction required.
Settle
Probiotics travel with airflow and colonize every surface they reach: duct walls, coils, supply vents, and all room surfaces including furniture, fabrics and floors.
Protect
The established microbial layer applies competitive exclusion — beneficial bacteria consume the organic matter that harmful microorganisms need to survive, suppressing mold, pathogens and odors 24/7.
INDEPENDENT LAB RESULT
75%
Reduction in surface allergens
Within the first 30 days of continuous use — including dust mite proteins, pollen and pet dander
What Probiotic HVAC Treatment Delivers
Combats Sick Building Syndrome
By eliminating the microbial root cause of SBS at source, occupants experience fewer headaches, less fatigue and improved respiratory comfort within weeks.
Balanced Indoor Microbiome
Creates a stable, healthy microbial ecosystem throughout the building — not a sterile, chemically-stripped environment that rebounds faster with pathogens.
Improved HVAC Efficiency
Biofilm-free coils and ducts maintain optimal airflow and heat-transfer efficiency — studies indicate up to 15% energy savings from cleaner HVAC components.
75% Allergen Reduction
Independent lab tests document up to 75% reduction in surface allergens — including dust mite proteins, pollen and pet dander — within the first 30 days of continuous use.
Persistent 24/7 Protection
Unlike chemical disinfectants that evaporate in minutes, the living probiotic layer is self-renewing and continuously active between cleaning cycles.
Extends System Lifespan
Reducing biofilm buildup decreases strain on fans, coils and heat exchangers — lowering maintenance frequency and extending the functional life of HVAC equipment.
