Spun polypropylene: A true multi-staged depth filter utilizing separate layers of micron filtration. Constructed spun polypropylene, these filters offer superior dirt holding capacity at an extremely economical price. Great filter for changing frequently, especially in well water applications, or with use in GrowoniX scrubbers.
Spun sediment is for high dirt blocking. They have more pressure drop than pleated, are less expensive, and catch dirt better than any other sediment filter.
