ECP Series cartridges are manufactured from a special formulation of resin-impregnated cellulose and polyester fibers.

This unique blend of materials provides a higher wet strength than regular cellulose cartridges. It also provides high flow rates and dirt holding capacity, while maintaining extremely low pressure drop.

The media is pleated around a polypropylene core for added strength and the ends are immersed in a thermo-setting vinyl plastisol. Embedding and sealing each end of the pleat block in this fashion fuses the components together forming a unified end cap and gasket.

ECP Series cartridge end caps feature a color-coding system for easy identification of micron ratings: Tan (1-micron), White (5-micron), Blue (20-micron), Yellow (50- micron).

The new ECP cartridges contain more media surface area than most competitive cartridges. The big blue 20" ECP cartridges contain 36 sqft of media.

Pentek filters
The flow through the filter appears to be slightly less than some other brands. Maybe a slight micron difference. The micron rating is not printed/embossed on the end cap like others. The filter is made in Mexico. While washing the filter, I noticed if you twist it, it is more flexible than others although I did not have any problems with it.
