Replace Electronic Furnace Filters for Your HVAC System

ECOairflow recommends replacing the filter pad every 3 months for residential models (Model 1000, 1500, and Dynamo). Commercial models (Model 2300 and M-Series) may last 3–6 months depending on air quality and usage load. ECOairflow offers a free email reminder service at ecoairflow.com/email-reminders to help you stay on schedule.

ECOairflow's electronic air cleaner pads are designed for replacement rather than washing. The glass-fiber mesh pads should be swapped out every 3 months. Used residential pads can often be recycled as post-consumer glass waste in many municipalities. The permanent aluminum or metal housing can be wiped clean with a dry cloth when replacing the pad.

For residential whole-home filtration, MERV 11 (Model 1000) or MERV 12 (Model 1500, Dynamo) provides excellent allergen and pathogen capture. Commercial applications typically require MERV 13–14 (Model 2300 Dynamo 2"). Healthcare facilities requiring ASHRAE 170 compliance should specify the M-Series MERV 14A or 16A hospital-grade filter.

Yes, all ECOairflow electronic air cleaners are ETL-certified to UL 2998 Zero Ozone Verification standards, emitting below 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 as safe for occupied residences, hospitals, classrooms, and commercial spaces.

Yes. ECOairflow filters are available in all industry-standard residential furnace cabinet sizes (e.g., 16×25, 20×25, 16×20) plus custom sizes, making them compatible as direct replacements for older systems from Honeywell, AprilAire, Lennox, GeneralAire, Carrier Infinity, and Trane CleanEffects. A Cabinet Conversion Kit is available for certain legacy commercial installations.

The M-Series Hybrid EAC (Model 2300 M-Series) is uniquely designed to maintain its full rated MERV performance whether powered, unpowered, or under ASHRAE Appendix J conditioning. This is critical for hospital treatment rooms where filtration performance must be assured even during a power loss. Standard residential models (Model 1000, 1500, Dynamo) are powered-only configurations.
