HEPA Filter Hospital Air Filtration Solutions for Healthcare

ASHRAE 170 and CSA Z317.2 set the minimum filtration standards for hospitals, mandating MERV 14A for emergency and treatment rooms and MERV 16A for operating rooms. HEPA is specifically required in protective environment and airborne infection isolation rooms. ECOairflow's M-Series MERV 14A and 16A configurations meet or exceed these mandated standards while reducing fan energy by up to 54%.

The M-Series patent-pending single pad replaces both the MERV 8 pre-filter and MERV 14/16 final bag filter in a traditional two-bank hospital configuration, reducing pressure drop from 0.6–1.2 in.w.g. to 0.13–0.37 in.w.c. This delivers full ASHRAE 170 compliance while cutting documented fan power consumption by 54% over a 12-week independent study.

Yes. The M-Series Hybrid EAC is unique in the electronic air cleaner category: it maintains its full rated MERV 14A or 16A performance whether powered, unpowered, or under ASHRAE Appendix J conditioning. This is critical for hospital treatment rooms where filtration performance must be guaranteed even during power interruptions or emergency conditions.

Absolutely. All ECOairflow hospital-grade products are UL 2998 Zero Ozone Certified, emitting below 0.0005 ppm (5 ppb)—well below the UL 867 regulatory limit of 0.005 ppm. They also exceed ASHRAE 170 emission standards for both ozone and formaldehyde, making them safe for ORs, ICUs, and Protective Environment Rooms where patient vulnerability is highest.

The M-Series MERV 14A configuration is approved for hospital emergency rooms, invasive procedure rooms, and general treatment areas under ASHRAE 170. The MERV 16A configuration is approved for operating rooms and high-acuity procedural spaces. The system is also suited for outpatient surgical centers, VA hospitals, long-term care facilities, and ambulatory surgery units requiring ASHRAE 241 infection-control compliance.

ECOairflow M-Series filters carry ASHRAE 52.2 Appendix J certification (MERV 14A and 16A in-situ), ASHRAE 170/CSA Z317.2 compliance documentation, ASHRAE 241 infection-control compliance, UL 2998 Zero Ozone certification, UL 867, CSA 22.2 No. 187, and ETL listing. Full submittal documentation, ASHRAE compliance data, and PM0.1 lab-test reports are available on request for specifying engineers and procurement departments.
