Commercial Air Cleaners for Dust, Smoke and VOCs

While the terms are often used interchangeably, commercial air cleaners like ECOairflow's EPT-based systems are typically integrated directly into a building's HVAC system to filter all conditioned air at the source. They use a polarized electromagnetic field to attract and capture particles, maintaining a low, nearly constant pressure drop throughout the filter's lifecycle. Portable air purifiers, by contrast, treat only a localized area. For commercial buildings, hospitals, and schools, in-duct electronic air cleaners provide whole-building coverage and are engineered to meet regulatory standards such as ASHRAE 62.1 and ASHRAE 170.

Hospitals require air filtration systems that meet strict standards. ECOairflow's M-Series™ 2" Hybrid E.A.C. (Model 2300) is ASHRAE 170/CSA Z317.2 compliant and certified to MERV 14A for treatment rooms and MERV 16A for operating rooms — meeting Appendix J conditioning requirements. All ECOairflow hospital-grade filters are UL 2998 Zero Ozone Certified, emitting below 0.0005 ppm, making them safe for use in occupied clinical spaces including ORs, ERs, ICUs, and treatment rooms. They are also recommended by the CDC and US EPA for occupied healthcare environments.

Most commercial buildings require a minimum of MERV 13 under ASHRAE 62.1 (2022) for acceptable indoor air quality. Healthcare facilities under ASHRAE 170 require MERV 14A for treatment rooms and MERV 16A for operating rooms. ECOairflow's commercial line covers MERV 12 through MERV 16A to meet a broad range of specifications.

Yes. All ECOairflow electronic air cleaners are UL 2998 Zero Ozone Certified, emitting below 0.0005 ppm (5 ppb) — well below the 0.005 ppm UL 867 regulatory threshold. They are recommended by the CDC and US EPA for use in occupied spaces including hospital operating rooms, classrooms, and commercial offices.

Unlike traditional pleated or bag filters that mechanically block particles and increase pressure drop as they load, ECOairflow's EPT electronic air cleaners use a polarized electromagnetic field to attract and capture particles. This maintains a nearly constant, low pressure drop throughout the filter's lifecycle, saving up to 54% in fan energy costs versus conventional filter trains.

Yes. ECOairflow's commercial air cleaners qualify for LEED EQ credits, WELL Building Standard compliance, International Living Future Institute (ILFI) credits, National Green Building Standard (NGBS) credits, and Passivehaus certification. Submittal documentation and LEED/ASHRAE compliance documents are available on request for specifying engineers.

Maintenance is straightforward: only the replaceable glass-fiber mesh pad requires periodic replacement, typically every 3–6 months in commercial applications. The permanent solid aluminum frame is a one-time capital investment. ECOairflow also offers a replacement pad subscription and email reminder service at ecoairflow.com/email-reminders to simplify upkeep.
