Electronic Air Cleaner Prefilters

Yes — electronic air cleaners like ECOairflow's M-Series deliver measurably superior filtration compared to passive filters at a significantly lower pressure drop. Independent testing shows 74.73% capture of PM0.1 ultrafine particles, 54% fan energy savings over 12 weeks, and compliance with ASHRAE 170 hospital standards. The reduced energy and maintenance costs provide a compelling return on investment.

The M-Series 2" Hybrid EAC is available in MERV 13, 14, 15, and 16 configurations. The MERV 14A variant is approved for hospital emergency rooms and treatment areas under ASHRAE 170, while the MERV 16A variant is approved for operating rooms and high-acuity procedural spaces. All ratings are maintained whether the unit is powered or unpowered.

Yes — the M-Series is unique in the electronic air cleaner category because it maintains its full rated MERV 13, 14, 15, or 16 performance whether powered, unpowered, or under ASHRAE Appendix J conditioning. This is critical for medical treatment rooms where filtration performance must be guaranteed even during a power interruption.

Yes. The M-Series is ASHRAE 170 and CSA Z317.2 compliant. MERV 14A is approved for emergency rooms, invasive procedure rooms, and treatment areas. MERV 16A is approved for operating rooms and high-acuity procedural spaces. It also meets ASHRAE 241 (2023) infection-control filtration requirements and exceeds ASHRAE 170 emission standards for both ozone and formaldehyde.

The M-Series single-pad design replaces both the MERV 8 prefilter and the MERV 14 bag filter in a traditional two-bank hospital configuration. Its low pressure drop — 0.13 to 0.37 in.w.g. versus 0.6 to 1.2 in.w.g. for conventional trains — enables a documented 54% reduction in fan power consumption over 12 weeks, allowing ASHRAE 170 compliance without the typical 60%+ fan energy penalty.

The M-Series holds ETL Listing (Intertek), UL 2998 Zero Ozone Verification (below 0.0005 ppm), UL 867, CSA 22.2 No. 187, and ASHRAE 52.2 Appendix J certification for MERV 14A and 16A. It also qualifies for LEED EQ credits, WELL Building Standard, ILFI, NGBS, and Passivehaus points, making it suitable for green building-certified projects.
