Iodine-catalyzed HEPA filtration for surgical suites, ICUs, isolation rooms, and critical care environments. Three-layer protection: physical capture + chemical neutralization + active biocidal inactivation.
Standard HEPA is passive — it physically traps particles but doesn't destroy what it captures. Iodine-catalyzed filtration is simultaneously a physical barrier, a chemical oxidizer, and an active biocidal agent.
H13-grade micro-fine borosilicate glass-fiber media captures airborne particulate ≥99.97% at 0.3 micron under the DOP test method — the most penetrating particle size. This captures bacteria, fungal spores (Aspergillus), viral aerosols, and respiratory droplet nuclei.
Unlike standard HEPA, the filter medium is impregnated with active iodine species. These react with and chemically disrupt the cell walls and protein structures of bacteria and viruses on contact. Pathogens are chemically neutralized — not merely held on filter fibers where they could remain viable and re-aerosolize during filter handling.
The combined physical and chemical mechanism achieves 99.9% pathogen neutralization — significantly exceeding what passive HEPA achieves through capture alone. This is the clinically relevant metric: not how many particles are captured, but how many viable pathogens are returned to zero.
Conventional HEPA filters capture microorganisms but leave them viable on filter surfaces for days to weeks. During routine filter changeout — which generates turbulence and disturbs the filter face — captured viable pathogens can re-aerosolize and expose maintenance personnel. Iodine-catalyzed media destroys captured organisms before changeout.
ASHRAE Standard 241 (Control of Infectious Aerosols, 2023) requires facilities to demonstrate Equivalent Clean Airflow (ECA) rates appropriate to occupancy type and headcount. We engineer and document ECA compliance for every space.
Post-COVID infectious aerosol control standard. Iodine Air Systems calculates ECA requirements and installs systems that meet or exceed the required clean air delivery rate for each room type.
Ventilation of Health Care Facilities. Surgical suite, isolation room, NICU, and pharmacy airflow rate, pressure relationship, and filtration efficiency requirements.
CDC Guidelines for Environmental Infection Control in Health-Care Facilities. Air changes per hour, negative-pressure isolation, and immunocompromised patient protection requirements.
Centers for Medicare & Medicaid Services facility requirements for hospital licensure and reimbursement eligibility. Compliance documentation available.
Environment of Care (EC) and Infection Control (IC) standards for Joint Commission accredited facilities. Our systems are engineered to support EC and IC compliance documentation.
EPA indoor air quality guidelines for healthcare settings. Iodine Air Systems exceeds EPA filtration efficiency thresholds for occupant health protection.
Surgical site infections (SSIs) are the leading HAI type by cost. ORs require positive pressure, ultra-clean HEPA supply, and minimum 20 ACH. Iodine-catalyzed filtration provides active pathogen destruction on the supply air stream before it reaches the sterile field.
Critically ill patients with compromised immune function are acutely vulnerable to opportunistic airborne pathogens — Aspergillus fumigatus, resistant gram-negative organisms, and viral respiratory infections. Ultra-high-efficiency filtration with active biocidal action provides the deepest available layer of airborne protection.
Airborne infection isolation (AII) rooms for TB, COVID-19, and other airborne-transmissible diseases require ≥12 ACH and true negative pressure. Exhaust air must be HEPA-filtered before re-circulation or building exhaust. Our units provide both requirements in a single installation.
Neonates in the NICU have no established immune response. Even low concentrations of airborne fungal spores or viral particles can cause systemic infections. Iodine-catalyzed filtration provides the highest available airborne protection for this critical population.
EDs see undifferentiated patients with unknown diagnoses, including active infectious disease. High patient throughput in open-plan environments creates significant aerosol accumulation risk. ASHRAE 241 ECA compliance is particularly important in high-occupancy ED waiting areas.
USP 795, 797, and 800 compounding pharmacy standards mandate ISO Class 5 to Class 8 environments. Our systems are engineered to maintain cleanroom classification through high-efficiency HEPA filtration and active particulate neutralization.
