iSpring FP25X25 High Capacity 20” x 2.5” Water Filter Replacement Cartridges - Fine Sediment Filter - 5 Micron - Pack of 25
About this item
- Protect Your Family and Household Appliance from Sediments: The FP25 sediment filters are specially designed to remove sediments, dust, sand, large particles, silt, dirt, and rust from water. They are usually used as the first stage of a water filtration system to prevent the filters that follow from getting clogged too soon. This filter can also be used for pool and hottub.
- Standard Size: Our filter fits standard 20” x 2.5” housings, including brand name models.
- The FP25 polypropylene sediment filter is able to achieve filtration down to 5 microns. The filters are tested by an independent third-party to meet NSF/ANSI standards. They have a capacity of 30,000 gallons of water, enough to supply a family of four with clean water for half a year (depending on your water quality). Water flow: up to 12 GPM.

- Please Note: The cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS). If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.

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.
-
Inner Spiral Pattern
Evenly separated spiral pattern increases pressure resistant, filtration area, and water flow.
