    The 91-005 replacement filter uses Ultravation Progressive Media filtration with Ultrastrand fiber technology, which meets and exceeds MERV 11 (ASHRAE 52.2) performance standards. Ultravation MERV 11 filters can capture particles as small as .3 microns. The specially shaped surface of an Ultrastrand fiber captures and holds particles far better than the typical round fiber. Ultrastrand fibers carry a permanent electrostatic charge that attracts particles like a magnet to increase capture ability further.

    Ultravation Progressive Media design increases fiber density from the upstream to the downstream side, gathering the largest particles in the first part of the filter while progressively smaller particles are captured through the filter. As a result, the media becomes filled edge to edge, providing a very high dirt-holding capacity.

    In the past, increased efficiency in particulate capture meant increased air resistance. However, the Ultravation Progressive Media design and UltraStrand-shaped fibers achieve MERV 11 performance with less pressure drop than a typical MERV 8 media filter. This increased performance with less pressure drop means you will get cleaner air in your home without sacrificing the efficiency of your HVAC system. With genuine Ultravation Progressive Media replacement filters, you truly do get more bang for your buck! 

    The Ultravation 91-005 replacement filter is also an upgrade for the Trion® Air Bear refill#: 255649-105 and 255649-005.
