Joint Commission EC.02.05.01 — the #1 most-cited deficiency chapter for hospital HVAC and ventilation — is within reach. Purity Guardian gives you the continuous documentation your facility needs, automatically.
The Joint Commission evaluates your facility's ability to maintain safe air quality and ventilation systems. EC.02.05.01 covers the built environment — and HVAC deficiencies are far and away the most common finding.
ASHRAE 170-2025 (最新版) defines specific ventilation requirements by room classification. Your monitoring must cover the parameters that apply to each space type in your facility.
Class A — Surgical suites
ORs must maintain positive pressure to prevent contamination from corridors. All parameters require continuous, timestamped monitoring — spot checks are not acceptable under current Joint Commission interpretation.
AII — Airborne Infection Isolation
Negative pressure prevents contaminated air from escaping to corridors. HEPA filtration is mandatory. All exhaust must be exhausted directly outdoors — recirculation is not permitted for AII rooms.
A regional hospital's surgical wing used paper logbooks to record filter replacement dates. When a Joint Commission surveyor requested HVAC maintenance records, the log showed the final-stage HEPA filters had been replaced 5 months before the required interval.
The surveyor found the discrepancy during a routine survey. Within 60 days, the facility was subject to a CMS validation survey, a state health department inspection, and a mandatory remediation of the HVAC system in three operating rooms.
The cost — $340,000 in remediation, legal fees, and productivity loss — was preventable with continuous electronic monitoring and automated alert escalation.
From continuous pressure monitoring to automated filter tracking — every feature is designed to satisfy Joint Commission and ASHRAE 170 documentation requirements.
Real-time sensor data for temperature, humidity, CO₂, PM2.5, VOCs, and pressure differentials — timestamped and always accessible.
Generate timestamped reports on demand or on schedule. Every reading is logged with audit-trail metadata — no manual entry required.
When any parameter exceeds threshold — pressure drops in an OR, humidity spikes in an isolation room — Purity Guardian alerts the right person immediately.
Automated filter lifecycle tracking with replacement reminders and timestamped logs — satisfying Joint Commission documentation requirements.
For facilities below grade or in high-radon zip codes — continuous radon risk tracking with EPA-based zone reporting and sensor alerts.
Connects to your existing building management system (BMS) via API. Works alongside your HVAC equipment — not in place of it.
Join healthcare facilities nationwide using PurityGuardian to document compliance, catch problems before they become findings, and protect the patients in their care.
PurityGuardian provides monitoring and documentation support. It is not a substitute for professional HVAC maintenance, legal compliance counsel, or official Joint Commission preparation. Compliance outcomes depend on your facility's specific equipment, practices, and operational context.
