Hayward Filter cartridge made with Remay (R) a patented material that has been the standard for the industry for over 30 years.  We recomend always buying the standard sizes realize that the 425 sq ft. filter versus the 400 sq ft.  is only few extra pleats and that is not worth the extra price.  also the pleats can become too close together its just marketing trying to up the size of filter rating.
