Geothermal Filters 30x36x2 for HVAC Air Cleaners

Yes. ECOairflow's 2" electronic air cleaners are specifically engineered for geothermal and commercial HVAC applications with face velocities of 500 FPM and higher. Their low pressure drop (as low as 0.13 in.w.c. at 300 FPM) ensures efficient airflow without stressing geothermal heat pump systems or air handlers.

Pressure drop ranges from 0.09–0.18 in.w.c. at 300 FPM for the M-Series Hybrid and 0.13 in.w.c. at 300 FPM for the Dynamo 2" EAC. At 500 FPM, the Dynamo reads 0.27 in.w.c. Both are dramatically lower than traditional MERV 8 + MERV 14 bag filter trains which typically measure 0.6–1.2 in.w.g.

No. ECOairflow filters are UL 2998 Zero Ozone Certified, emitting less than 0.0005 ppm (5 ppb) of ozone—well below the UL 867 regulatory limit of 0.005 ppm. They are recommended by the US CDC and US EPA for safe use in occupied spaces, including healthcare environments, classrooms, and offices.

Replacement frequency depends on the application and air quality conditions. In commercial settings, pads are typically replaced every 3–6 months. ECOairflow offers an email reminder subscription service at ecoairflow.com to help facilities manage pad replacement schedules efficiently. The permanent aluminum frame requires no replacement.

Yes. ECOairflow 30x36x2 geothermal filters qualify for LEED EQ credits and are compliant with WELL Building Standard, Passivehaus, International Living Future Institute (ILFI), and the National Green Building Standard (NGBS). They also support ASHRAE 62.1 IAQ Procedure and ASHRAE 90.1 fan power limitation compliance.

The Dynamo 2" EAC (Model 2300) is a powered-only MERV 14 electronic air cleaner ideal for commercial and geothermal applications. The M-Series Hybrid EAC (Model 2300 M-Series) adds a patent-pending hybrid pad that maintains full MERV 13–16 performance whether powered, unpowered, or under ASHRAE Appendix J conditioning—making it suitable for hospital and mission-critical environments.
