16x25x1 MERV 13 Furnace Filters

Our MERV 13 furnace filters are our pride and joy. MERV 13 is the highest rated filter that you can safely use in most modern furnace and air conditioner systems. Our furnace filters meet or exceed the ASHRAE 52.2 rating to be qualified as a MERV 13 filter. A MERV 13 filter must be able to filter >90% @ 3-10 microns and >90% @ 1-3 microns and more importantly <75% @ .03-3 microns. 

Furnace Filters under MERV 13 have no rating at .03-3 microns as they do not have the filtration capability to capture particles at this size. 

All of our MERV 13 filters are electrostatically charged which allows them to capture more dust than a conventional pleated furnace filter. They also do not promote the growth of mildew, bacteria and fungi.
