iSpring Universal PP Sediment Filters

Different water filters have different purposes. Some are designed to remove chemicals from water. Others remove metallic contaminants, dissolved solids, or charged particles. Polypropylene sediment filters are usually placed as the first stage of the water filtration system to remove suspended solids, variously referred to as turbidity, sediment, or particulate.

PP sediment filters are widely used as beds of natural media like garnet, sand, and anthracite to filter out unwanted particles like dirt and iron rust.

In general, flow rates for sediment filters are higher than equally sized carbon or media filters. The tighter the filter is, the slower the flow will be. iSpring provides a wide variety of micron sizes to suit your specific need.


iSpring sediment filters are compatible with most water filtration systems' housing on the market.

Pattern

Inner Spiral Pattern

Evenly separated spiral pattern increases pressure resistant, filtration area, and water flow.

Structure

Multilayered Structure

Sparse Layer: Large particles are filtered to extend the filter life.

Compaction Layer: Made with fine fiber and filters smaller particles that passed through the sparse layer.

Precision Layer: Small dust is filtered to assure efficiency of water filtration process in the following stages.
