16x25x5 Ultravation Progressive Media MERV-11 Media
The next generation in pleated filters,
UltravationProgressive Media performs well beyond regular pleated filters in the four most important areas of performance: particle capture, holding capacity, initial efficiency and pressure drop.
MERV 11 performance:
85% efficient on particles 3 to 10 microns
Ultravationpleated media filters meet and exceed MERV 11 (ASHRAE 52.2) performance standards using unique, UltraStrandshaped fibers. The especially shaped surface of an UltraStrandfiber captures and holds particles far better than the typical round fiber, because of its rough, irregular surface and increased surface area. To increase capture ability still further, UltraStrandfibers carry a permanent electrostatic charge that attracts particles like a magnet.
