Flanders PREpleat M13 is a MERV 13 extended-surface pleated air filter designed for commercial and industrial HVAC applications requiring capture of fine particulates including bacteria, virus carriers, smoke, and microscopic allergens. The 100% synthetic gradient-density media achieves its MERV 13 rating mechanically, delivering stable efficiency that does not dissipate over time. Diamond-shaped expanded metal backing and a heavy-duty moisture-resistant frame provide high dust-holding capacity with low pressure drop.
