Air Cleaners HEPA vs Electronic for Commercial HVAC

ECOairflow electronic air cleaners are designed for continuous 24/7 operation within your HVAC system. Consuming only 2 Watts of power and producing an ultra-low pressure drop, they add negligible operating cost. Unlike standalone HEPA units, ECOairflow EACs integrate directly into your existing forced-air system, filtering all conditioned air automatically without any manual intervention.

HEPA filters use mechanical fiber barriers that cause high pressure drop (0.6–1.2 in.w.g.), significantly increasing fan energy costs. Electronic air cleaners like ECOairflow's EPT-based products use electromagnetic attraction across glass-fiber mesh, delivering MERV 14–16 performance at pressure drops as low as 0.13 in.w.c. — dramatically reducing fan energy while surpassing HEPA at PM0.1 particle capture.

ASHRAE 170 requires a minimum of MERV 14 for hospital emergency rooms, invasive procedure rooms, and treatment areas, and MERV 16 for operating rooms and high-acuity procedural spaces. ECOairflow's M-Series Hybrid EAC is ASHRAE 170 and CSA Z317.2 compliant, certified at MERV 14A and MERV 16A under ASHRAE 52.2 Appendix J in-situ protocol.

ECOairflow electronic air cleaners are UL 2998 Zero Ozone Certified, emitting ozone at levels below 0.0005 ppm (5 ppb) — well under the 0.005 ppm UL 867 regulatory threshold. They exceed US FDA, EPA, NIOSH, OSHA, and California CARB ozone standards and are recommended by the CDC and US EPA for use in occupied healthcare, residential, and commercial spaces.

ASHRAE 52.2 Appendix J is an in-situ filter performance protocol that certifies a filter maintains its rated MERV performance throughout its entire service lifecycle, not just at initial installation. ECOairflow's M-Series Hybrid EAC is Appendix J certified at MERV 13-A through 16-A, meaning clinical filtration performance is assured even as the pad loads — critical for hospital treatment and operating rooms.

Yes. ECOairflow electronic air cleaners qualify for LEED EQ credits for indoor air quality and ventilation efficiency. Their UL 2998 Zero Ozone certification, ASHRAE 62.1 IAQ Procedure compliance, low pressure drop supporting ASHRAE 90.1 fan power compliance, and use of recyclable glass-fiber pads all contribute to LEED, WELL Building Standard, ILFI, NGBS, and Passivehaus credit eligibility.
