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 in size. The specially shaped surface of an Ultrastrand fiber captures and holds particles far better than the typical round fiber. To increase capture ability still further, Ultrastrand fibers carry a permanent electrostatic charge that attracts particles like a magnet.

Ultravation Progressive Media design increases fiber density from the upstream to 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 very high dirt holding capacity.

In the past increased efficiency in particulate capture has always meant increased air resistance. But 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!

REPLACE every 6 Months, 4 Months to challenging environments with pets that shed, active children and wal-to-wal carpeted homes or offices.
