MERV 12 Furnace Filters for Whole-Home Air Cleaners

Goodman furnaces typically use standard residential cabinet sizes including 16x25, 20x25, 16x20, and 20x20 inch filters. ECOairflow's MERV 12 electronic air cleaners are available in all industry-standard residential furnace cabinet sizes plus custom sizing for non-standard installations. Check your furnace manual or existing filter frame for the exact dimensions before ordering.

ECOairflow recommends replacing the glass-fiber collection pad every 3 months for optimal filtration performance. The permanent metal housing is a one-time purchase — only the pad is replaced. A free email reminder service is available at ecoairflow.com/email-reminders to help you stay on schedule without guesswork.

ECOairflow's MERV 12 electronic air cleaners capture a broad spectrum of airborne contaminants including dust, pollen, pet dander, mold spores, viruses, bacteria, formaldehyde, wildfire smoke (PM2.5 and PM0.1), traffic-related air pollution, and radon daughter progeny. The Dynamo 1" model captures particles as small as 0.001 microns — twice as effective as HEPA at ultra-fine particles.

No. Both the Model 1500 and Dynamo 1" EAC are configured for zero ozone emission. The Dynamo 1" EAC is UL 2998 Zero Ozone Certified by Intertek, measuring below 0.0005 ppm — well within EPA and CDC safety guidelines for occupied residences, making them safe for homes with children, pets, asthma sufferers, and respiratory sensitivities.

Both are MERV 12 residential electronic air cleaners, but the Dynamo 1" EAC offers a lower pressure drop (0.11 vs 0.13 in.w.c.), finer particle capture (0.001 vs 0.007 microns), a patented one-piece pad for easier maintenance, UL 2998 Zero Ozone Certification, and a lifetime electronics warranty to the original owner versus the Model 1500's 5-year warranty.

Yes. The Dynamo 1" EAC is tandem-capable, allowing multiple units to operate on a single 24V line for light-commercial deployments such as small offices and retail spaces. ECOairflow's broader product line also includes dedicated commercial models. LEED-compliant construction and hermetically sealed electronics make these units suitable for green building projects.
