The Ultra grade spun from PRISM, delivers exceptional 97% efficiency, with a low clean pressure drop at an affordable price. Finer fibres used in the construction create a more accurate level of filtration, whilst maintaining a high dirt holding capacity. The DSPP-U with its melt-bonded exterior minimises any fibre migration, whilst its single, one piece, graded density and thermally bonded fibre construction made from 100% polypropylene introduces no binders, lubricants, or other additives in its manufacture.
