Custom Air Filters for AC & Furnace Systems

ECOairflow manufactures filters in all industry-standard sizes as well as custom sizes to fit non-standard AC and furnace systems. Whether your HVAC unit requires a common dimension or a unique cut, ECOairflow can accommodate the requirement. Contact customer service to confirm sizing for your specific application.

ECOairflow filters produce zero ozone. All models are certified by Intertek (ETL) to the UL 2998 Zero Ozone Verification standard, which is below 0.0005 ppm (5 ppb). This exceeds ozone emission standards set by the FDA, NIOSH, CARB, EPA, and OSHA, making them safe for residential and sensitive commercial environments.

ECOairflow filters use patented Electronic Polarization Technology (EPT). A low-voltage charge (24V) polarizes the filter media, creating an electrostatic field that attracts and traps particles as small as 0.001 microns — including viruses, bacteria, wildfire smoke, radon daughter progeny, and ultrafine automotive pollution — far beyond what standard mechanical filters can achieve.

ECOairflow recommends replacing filter pads every 3 months under normal operating conditions. The pad replacement process is simple: open the filter frame, remove the old pads, and drop in new ones. The low pressure drop design also means pads accumulate material more gradually, potentially reducing the frequency of changes compared to traditional throwaway filters.

Yes. The Dynamo 2" E.A.C. and M-Series Hybrid are specifically engineered for commercial and geothermal applications. They qualify for credits under LEED, WELL Building, ILFI, NGBS, and Passivehaus standards. The M-Series Hybrid also meets ASHRAE Appendix J requirements, maintaining full MERV-rated performance whether powered or unpowered — critical for hospital and laboratory environments.

Warranty coverage varies by model. The Dynamo 1" E.A.C. offers a lifetime warranty on electronics and a 10-year warranty on all components to the original owner. The Model 1000, Model 1500, Dynamo 2", and M-Series Hybrid include a 5-year limited warranty on electronics and all components from the date of manufacture. Warranty does not cover labor or shipping costs.
