100% Polypropylene cartridges. Multi-layered construction for true depth filtration. The multi-layer graded density captures particles throughout the entire cross section of the cartridge & reduces surface binding. The woven melt blown manufacturing technique guarantees a more accurate rating and consistent flow with low pressure drop. NSF and FDA approved materials.
