Electrostatic Pleated Air Filters: What the Label Means
Some disposable HVAC filters are described as electrostatic pleated filters.
Pleats Increase Media Area
Pleated construction allows more filter material to fit within the frame than a flat sheet design.
Electrostatic Is a Product Feature
The term can describe filter media designed to use electrostatic properties as part of particle capture.
Exact construction differs by manufacturer.
MERV Is Still Important
An electrostatic label does not replace the MERV rating. Check both specifications when comparing products.
Confirm Dimensions
A 14x24x1 or 20x20x1 filter can have actual dimensions slightly smaller than its nominal size.
Conclusion
Compare MERV rating, actual dimensions, pleated construction, and HVAC compatibility rather than relying on “electrostatic” alone.
