Frequently Asked Questions
Are electrostatic furnace filters good?
Yes. ECOairflow's electrostatic furnace filters use patented Electronic Polarization Technology (EPT) to capture particles as small as 0.001 microns — including viruses, wildfire smoke, bacteria, allergens, and radon daughter progeny. They achieve MERV 11–12 ratings and are ETL-certified to UL 2998 Zero Ozone standards, making them significantly more effective than standard disposable pleated filters at ultra-fine particle capture.
How long do electrostatic filters last?
ECOairflow's permanent metal filter housings are designed to last indefinitely as a one-time capital purchase. The replaceable glass-fiber pads inside should be changed every 3 months. The Dynamo 1" EAC carries a lifetime electronics warranty to the original owner, while Model 1000 and Model 1500 include a 5-year limited warranty on electronics and all components.
What MERV rating do ECOairflow electrostatic furnace filters have?
ECOairflow offers MERV 11 (Model 1000) and MERV 12 (Model 1500 and Dynamo 1" EAC) electrostatic furnace filters, all rated per ASHRAE 52.2 standards. MERV 12 units capture particles down to 0.007–0.001 microns, providing superior protection compared to typical MERV 8 disposable filters commonly found in homes.
Do electrostatic filters produce ozone?
ECOairflow's electronic air cleaners are ETL-certified to the UL 2998 Zero Ozone Verification standard, meaning they emit zero detectable ozone. They exceed ozone emission standards set by the US FDA, NIOSH, California CARB, EPA, and OSHA, making them completely safe for use in occupied residences including homes with children, pets, and individuals with asthma.
Can electrostatic furnace filters capture viruses and bacteria?
Yes. ECOairflow's electrostatic filters use Electronic Polarization Technology to capture airborne particles as small as 0.001 microns, which includes viruses, bacteria, and respiratory pathogens. The Dynamo 1" EAC is twice as effective as HEPA filters at ultra-fine particle capture in the PM0.1 range, making it particularly effective for households with vulnerable occupants.
What sizes are available for ECOairflow electrostatic furnace filters?
ECOairflow electrostatic filters are available in all industry-standard residential furnace cabinet sizes, including common dimensions such as 16x25, 20x25, 16x20, 20x20, 14x25, and 18x25 inches. Custom sizing is also available for non-standard HVAC installations. Each model fits directly into the existing filter slot with a 1-inch profile.
How much energy can I save with an ECOairflow electrostatic filter?
ECOairflow's electrostatic furnace filters feature ultra-low pressure drops — as low as 0.11 in.w.c. at 300 FPM for the Dynamo 1" EAC — which reduces the workload on your furnace blower motor. This can result in savings of up to 15% per year on heating and cooling costs compared to conventional high-MERV disposable pleated filters, with power consumption under 2 watts.
